Updated November 4, 2026
Metro 2033 Redux running worse with DLSS enabled? Some PC players are experiencing severe FPS drops, low GPU usage with DLAA, or sudden stuttering after the next-gen update.
On certain RTX 5080 systems, enabling DLSS has reportedly reduced performance from around 300 FPS to just 50 FPS. Other players experience significant slowdowns with Neural Rendering or sudden frame-rate drops during combat, even when DLSS is disabled.
If you're experiencing these problems, start by disabling Neural Rendering and comparing DLSS Quality against 4A TSR. If performance remains unusually low, the problem may involve NVIDIA driver settings, rendering compatibility, or broader frame-time instability.
This guide covers the most useful troubleshooting steps for DLSS low FPS, DLAA performance problems, RTX 50-series GPUs, and Linux/Proton stuttering.
Quick Answer: How to Fix Metro 2033 Redux DLSS Low FPS
If DLSS makes Metro 2033 Redux run slower after the next-gen update, try these steps in order:
- Disable Neural Rendering (DLSS-NR). This feature can significantly increase GPU workload.
- Test DLSS Quality with NR disabled. Compare FPS in the same gameplay location.
- Switch to 4A TSR. If performance improves, the slowdown may be specific to the DLSS rendering path.
- Test DLAA separately. Check for unusually low GPU usage or severe FPS loss.
- Reset NVIDIA game-specific overrides. Remove custom DLSS and frame-rate settings temporarily.
- Check your NVIDIA driver. Install an appropriate update if available, then retest.
- Test Advanced PhysX and tessellation settings if stuttering continues without DLSS.
- On Linux, check NVIDIA drivers and Proton compatibility.
Important: These steps help isolate the problem. They are not guaranteed fixes for every configuration. If DLSS remains unstable, native rendering or 4A TSR may be the best temporary alternative.

Which Metro 2033 Redux Performance Problem Are You Experiencing?
Not every FPS drop has the same cause. Use this table to identify the most relevant troubleshooting section.
If you are unsure which problem applies, begin with the DLSS comparison test.
Why Does DLSS Cause Low FPS in Metro 2033 Redux?
The next-gen update introduces modern graphics features, including NVIDIA DLSS, AMD FSR, and 4A TSR.
DLSS Super Resolution normally improves performance by rendering the game at a lower internal resolution and reconstructing the image.
However, some players are experiencing the opposite behavior.
Reported symptoms include:
- FPS dropping from approximately 300 to 50 when enabling DLSS.
- DLSS Ultra Performance running worse than expected.
- DLAA causing GPU utilization to fall dramatically.
- Severe frame-time spikes during combat or exploration.
- Stuttering that continues with DLSS disabled.
- Different performance results between Windows and Linux.
These symptoms can have different causes.
DLSS Super Resolution vs DLSS 5 Neural Rendering
Understanding the difference is important before changing settings.
DLSS Super Resolution reconstructs a higher-resolution image from a lower internal rendering resolution. It is primarily intended to improve performance while maintaining image quality.
DLAA uses NVIDIA's AI-based anti-aliasing technology at native resolution. It focuses on image quality rather than the performance gains associated with upscaling.
DLSS 5 Neural Rendering (DLSS-NR) uses AI to enhance aspects of the rendered image, including lighting and material appearance. It adds GPU workload and can substantially reduce FPS.
Neural Rendering is intended for supported RTX 50-series hardware and compatible systems.
This distinction matters because a large FPS reduction with NR enabled does not necessarily mean ordinary DLSS Super Resolution is malfunctioning.
However, if DLSS causes severe FPS loss with NR already disabled, additional troubleshooting is necessary.
Fix 1: Disable DLSS Neural Rendering First
If your FPS drops dramatically after enabling DLSS, check whether Neural Rendering is active.
DLSS-NR can require considerably more GPU processing power than ordinary DLSS upscaling.
How to disable Neural Rendering
- Launch Metro 2033 Redux.
- Open the game's video or graphics settings.
- Enable DLSS if necessary to display the related options.
- Look for DLSS-NR (Neural Rendering).
- Set Neural Rendering to Off.
- Keep your DLSS upscaling mode unchanged.
- Apply the settings and return to gameplay.
Compare performance in the same location.
The DLSS-NR option may only appear when DLSS is enabled and the system supports the feature.
If you cannot find the setting, do not assume Neural Rendering is active.
What should happen after disabling NR?
If FPS improves substantially, Neural Rendering was contributing to the slowdown.
That does not automatically mean the feature is broken. Advanced rendering effects can carry a significant performance cost even when functioning correctly.
For example, an RTX 5070 Ti player reported performance dropping from approximately 220 to 90 FPS with NR enabled at 3440×1440.
If your FPS remains unusually low with Neural Rendering disabled, continue to Fix 2.
Tip: Compare performance in the same area. Different Metro locations can have substantially different lighting, particle effects, enemy activity, and rendering workloads.
Fix 2: Compare DLSS, DLAA and 4A TSR
One of the best ways to investigate the problem is to compare different rendering modes under similar conditions.
Metro 2033 Redux supports multiple upscaling technologies, so you do not have to rely on DLSS if it performs poorly.
Recommended performance comparison
Keep your resolution, graphics quality, gameplay location, and frame-rate limit consistent.
For each test, record:
- Average FPS
- Lowest observed FPS
- GPU utilization
- Frame-time spikes
- Visible stuttering
Use the same scene for each comparison. Where possible, choose equivalent image-quality settings rather than comparing unrelated presets.
What do the results mean?
DLSS runs much slower than native resolution
This may indicate a driver interaction, rendering compatibility issue, or conflicting configuration.
DLAA causes unusually low GPU usage
Check frame limits, driver overrides, and other possible rendering bottlenecks.
4A TSR runs smoothly while DLSS does not
The slowdown may be associated with the NVIDIA rendering path on your configuration.
Every rendering mode stutters
The problem may involve broader frame-time instability rather than DLSS itself.
Should you switch to 4A TSR?
If 4A TSR provides more consistent frame times and acceptable image quality, it is a reasonable alternative.
You do not need to use DLSS simply because your system has an NVIDIA GPU.
For now, prioritize stable performance over a particular upscaling technology.
Fix 3: Check NVIDIA Drivers and DLSS Overrides
Custom NVIDIA settings can sometimes affect how games handle rendering, synchronization, and upscaling.
Before changing several in-game options, inspect your graphics driver configuration.
Step 1: Check for NVIDIA driver updates
On Windows:
- Open the NVIDIA App.
- Navigate to the Drivers section.
- Check for an available compatible driver.
- Review its release notes for relevant game fixes.
- Install an appropriate update if necessary.
- Restart your PC.
- Test Metro 2033 Redux again.
A newer driver is not automatically a confirmed fix for this specific problem.
If the game previously worked correctly, record your current driver version before making changes.
Step 2: Reset custom NVIDIA overrides
Open the NVIDIA App or NVIDIA Control Panel and inspect the profile associated with Metro 2033 Redux.
Check for modifications involving:
- DLSS overrides
- Maximum frame rate
- VSync
- Power management
- Image scaling
- Other game-specific rendering settings
Temporarily restore customized settings to their defaults where possible.
Then launch the game and test DLSS again.
Avoid forcing additional DLSS profiles or presets unless you have a specific reason to test them.
Step 3: Check frame-rate limits
Frame caps can make performance comparisons misleading.
For example, if the game is capped at 120 FPS, changing the upscaler may not produce a visible increase above that limit.
Check:
- In-game frame-rate limits, if available.
- NVIDIA's maximum frame-rate setting.
- External frame limiters.
- VSync and display synchronization settings.
Use a consistent configuration while comparing rendering modes.
Do not disable VSync permanently just because another player suggested it. VSync and G-Sync configurations vary, and changing synchronization settings does not guarantee a fix for severe DLSS performance loss.
Fix 4: DLAA Causes Low GPU Usage or Unexpected FPS Loss
Another reported issue involves DLAA reducing GPU utilization dramatically.
For example, GPU usage may fall from nearly 100% to approximately 20% after switching rendering modes, accompanied by a major FPS reduction.
DLAA can naturally run slower than DLSS Quality because it does not gain performance by lowering the internal rendering resolution.
However, a severe GPU utilization collapse alongside unusually poor performance deserves additional investigation.
Step 1: Compare DLAA against DLSS Quality
Test both options in the same gameplay area.
Keep Neural Rendering disabled and avoid changing unrelated settings.
If DLSS Quality runs normally but DLAA produces severe performance loss, the problem may be associated with that rendering configuration.
Step 2: Check GPU and CPU utilization
Use a monitoring tool to observe:
- GPU usage
- GPU clock speed
- GPU power consumption
- CPU utilization
- Frame times
Low GPU usage alone does not prove that the graphics driver is broken.
CPU limitations, frame caps, synchronization behavior, or rendering problems can prevent the GPU from reaching full utilization.
Step 3: Check for conflicting settings
Restore unnecessary NVIDIA overrides to their defaults.
Make sure an unexpected frame cap is not influencing your results.
Step 4: Try another rendering mode
Switch back to DLSS Quality or 4A TSR.
If performance returns to normal, continue using the stable option while investigating the DLAA-specific slowdown.
Avoid changing multiple settings at once. Otherwise, it becomes difficult to identify which adjustment actually helped.
Fix 5: Severe Stuttering Even With DLSS Disabled
Not every Metro 2033 Redux performance problem is caused by DLSS.
Some players experience sudden frame-rate drops during combat or exploration even when switching DLSS on or off makes little difference.
For example, the game may normally run at a high frame rate but occasionally drop into single digits.
If this describes your problem, focus on frame-time stability rather than upscaling alone.
Step 1: Test tessellation settings
Tessellation increases geometric detail and can affect GPU workload.
If the game exposes tessellation controls:
- Record your current setting.
- Reduce tessellation by one level.
- Return to an area where stuttering occurs.
- Compare frame-time consistency.
Lowering tessellation may help certain configurations, but it is not a universal fix.
Step 2: Check Advanced PhysX
The next-gen update enables Advanced PhysX by default on PC.
PhysX effects can add workload during scenes involving particles and physics interactions.
If your version exposes a configurable Advanced PhysX option:
- Record its current setting.
- Temporarily disable or reduce it.
- Restart the game if required.
- Test the same gameplay location.
If performance improves consistently, the setting may be contributing to the slowdown.
Do not assume PhysX is responsible without a repeatable difference.
Step 3: Temporarily disable overlays
Try running the game without unnecessary overlays.
Examples include:
- Steam Overlay
- NVIDIA Overlay
- Discord Overlay
- Third-party recording overlays
- Additional monitoring overlays
Disable them individually when possible.
If one overlay is responsible, you can leave it disabled specifically for Metro 2033 Redux.
Step 4: Monitor frame times
Average FPS does not tell the whole story.
A game can report 150 FPS and still feel unstable if individual frames occasionally take much longer to render.
Watch for sharp spikes in a frame-time graph while playing.
Compare the results before and after changing each setting.
Step 5: Verify game files on Steam
- Open your Steam Library.
- Right-click Metro 2033 Redux.
- Select Properties.
- Open Installed Files.
- Click Verify integrity of game files.
- Wait for verification to finish.
This can repair missing or damaged game files.
However, it will not necessarily resolve a rendering bug.
Avoid deleting DLL files or modifying engine files as a first troubleshooting step. Such changes can introduce additional problems and complicate future updates.
Fix 6: Metro 2033 Redux DLSS Low FPS on Linux and Proton
Linux players may experience different DLSS behavior compared with Windows users.
Some configurations encounter severe performance loss under Proton, while others work normally.
That does not prove every problem is caused by NVIDIA's Linux driver, but driver and compatibility testing can help isolate the issue.
Step 1: Check your NVIDIA Linux driver
Confirm that your installed NVIDIA driver supports your GPU and the rendering features you are using.
Check compatibility with your Linux distribution and graphics stack before changing drivers.
Step 2: Test another Proton version
In Steam:
- Open your Library.
- Right-click Metro 2033 Redux.
- Select Properties.
- Open Compatibility.
- Enable Force the use of a specific Steam Play compatibility tool if needed.
- Select another available Proton version.
- Launch the game and compare performance.
Record the Proton version and results.
Do not assume Proton Experimental or an older release will always perform better.
Step 3: Remove unnecessary launch options
If you use custom Steam launch parameters, record them before temporarily removing nonessential overrides.
Then retest with a simpler configuration.
Step 4: Compare DLSS against 4A TSR
Keep the same gameplay location and graphics settings.
If DLSS performs poorly but 4A TSR works normally, the alternative upscaler may be the most practical temporary solution.
Step 5: Check native Linux versus Proton differences
If both a native Linux build and Windows-through-Proton configuration are available, remember that they may not expose identical graphics features.
Do not assume the native version includes every next-gen rendering option available in the Windows build.
Compare only features actually supported by each configuration.
Best Metro 2033 Redux Graphics Settings to Test First
There is no single graphics preset that fixes every DLSS-related performance problem.
However, the following settings provide a useful diagnostic starting point.
These are troubleshooting settings, not a benchmarked universal performance preset.
What if DLSS still runs worse than native resolution?
If performance remains poor after testing NR, driver overrides, and alternative rendering modes:
- Return to the configuration that runs smoothly.
- Avoid repeatedly changing unrelated settings.
- Check for game and driver updates.
- Record your GPU, driver version, resolution, and affected DLSS modes.
If only DLSS produces the severe slowdown, continuing with native rendering or 4A TSR is a reasonable workaround.
Can you return to the previous Metro Redux version?
If the next-gen update causes persistent problems, Steam and GOG provide legacy branches for compatible PC installations.
On Steam, open the game's Properties, select Game Versions & Betas or Betas (depending on the Steam interface), and look for the metro_2033_redux_legacy branch.
Switching to the legacy version is a fallback option, not a DLSS fix. The older build may not contain the next-gen graphics features.
Back up important saves and settings before changing versions, and do not assume that progress or configuration files will behave identically between builds.
Has 4A Games Fixed the Metro 2033 Redux DLSS Performance Issue?
The next-gen update introduced modern upscaling, higher-quality graphics, uncapped frame rates, and numerous bug fixes.
A subsequent PC hotfix addressed problems involving resolution detection, Steam Overlay behavior, account rewards, achievements, and localization.
However, a universal fix for the reported DLSS-related FPS collapse has not been confirmed.
This distinction matters because players are describing several different problems:
- Neural Rendering significantly reducing FPS.
- Ordinary DLSS performing unusually poorly with NR disabled.
- DLAA causing unexpectedly low GPU utilization.
- Severe stuttering continuing regardless of the upscaler.
A fix for one issue may not address the others.
You can check the latest announcements on the Metro 2033 Redux Steam news page.
For unresolved technical problems, you can also contact PLAION Player Support.
Until a specific fix is confirmed, the safest approach is to identify which rendering option triggers the slowdown and use a stable alternative.
Frequently Asked Questions
Why does DLSS reduce FPS in Metro 2033 Redux?
DLSS can perform unexpectedly poorly because of rendering compatibility problems, driver interactions, conflicting settings, or additional GPU workload from Neural Rendering. Severe FPS loss with ordinary DLSS and NR disabled should be investigated separately.
How do I disable DLSS Neural Rendering?
Open the game's graphics settings, enable DLSS if necessary, and look for DLSS-NR (Neural Rendering). Disable the option and retest without changing other settings. The option may not appear on unsupported hardware.
Is DLSS 5 Neural Rendering worth enabling on an RTX 5080?
It depends on your preferred balance between image quality and performance. Neural Rendering can significantly increase GPU workload, even on powerful hardware. If it causes unacceptable FPS loss, disabling it is a reasonable choice.
Why does DLAA cause low GPU usage?
DLAA may run slower than DLSS upscaling, but extremely low GPU utilization alongside severe FPS loss can indicate another bottleneck or rendering issue. Check frame limits, NVIDIA overrides, and GPU and CPU performance before assuming a hardware fault.
Is 4A TSR better than DLSS in Metro 2033 Redux?
Neither is universally better. Performance and image quality depend on your hardware and settings. If DLSS causes severe slowdowns, 4A TSR may provide a smoother alternative.
How do I fix Metro 2033 Redux stuttering with DLSS disabled?
Test tessellation, Advanced PhysX, overlays, frame limits, and game-file integrity. If stuttering occurs across all rendering modes, the issue may not be related to DLSS.
Does Metro 2033 Redux DLSS work on Linux and Proton?
DLSS behavior can vary depending on NVIDIA Linux drivers, Proton versions, and graphics settings. Try supported Proton configurations and compare DLSS against an alternative upscaler if performance is unusually poor.
Has the Metro 2033 Redux DLSS low-FPS bug been fixed?
A universal fix for the reported DLSS FPS regression has not been confirmed. Check official game announcements and NVIDIA driver release notes for changes relevant to your specific symptoms.
Final Thoughts
If Metro 2033 Redux runs worse after enabling DLSS, start by disabling Neural Rendering and comparing DLSS Quality against 4A TSR.
If ordinary DLSS remains much slower than native rendering with NR disabled, check NVIDIA driver overrides and frame-rate settings.
For severe stuttering that continues with DLSS off, focus on frame-time stability, Advanced PhysX, tessellation, and overlays.
The most useful troubleshooting method is to change one setting at a time. This helps identify the actual cause instead of applying several unrelated tweaks.
If the next-gen build remains unstable, using a working alternative upscaler or returning to the available legacy version may be preferable while waiting for a compatible update.
Still experiencing FPS drops? Share your GPU model, NVIDIA driver version, Windows or Linux setup, resolution, DLSS mode, and whether Neural Rendering is enabled. These details can help identify which configurations are affected.
