The evolution of graphics in video games has been nothing short of revolutionary, with ray tracing and AI-driven technologies like DLSS (Deep Learning Super Sampling) leading the charge toward unprecedented realism. NVIDIA's DLSS technology has undergone several iterations, each improving the quality of visuals while maintaining performance. With the introduction of DLSS 4, the synergy between ray tracing and this AI-powered upscaling technology has reached new heights. In this blog post, we’ll explore how DLSS 4 complements ray tracing in games and whether it makes ray tracing more accessible to gamers with mid-range GPUs.
What is Ray Tracing?
Ray tracing is a rendering technique that simulates the physical behavior of light to create more realistic lighting, shadows, reflections, and other visual effects in real-time. Unlike traditional rasterization, which approximates how light behaves, ray tracing traces the paths of individual rays of light and computes how they interact with objects and surfaces. The result is stunningly lifelike images with more natural lighting, accurate reflections, and realistic shadows.
However, ray tracing is computationally intensive. It requires significant processing power, often taxing even the most powerful graphics cards. As a result, it can lead to performance drops, especially in more graphically demanding games.
What is DLSS?
Deep Learning Super Sampling (DLSS) is a technology developed by NVIDIA to address the performance impact of ray tracing and other demanding graphics features. DLSS leverages AI and machine learning to upscale lower-resolution images to a higher resolution without compromising visual quality. Essentially, DLSS renders a game at a lower resolution and then uses a neural network to reconstruct the image at a higher resolution in real-time. This results in better performance, smoother frame rates, and the ability to run ray tracing effects without sacrificing visual fidelity.
DLSS 4: What’s New?
DLSS 4 builds upon its predecessors, offering better image quality and performance improvements. While DLSS 2 and 3 introduced significant gains in performance and image upscaling, DLSS 4 continues to refine these capabilities. One of the standout features of DLSS 4 is its enhanced AI-driven upscaling, which provides even more accurate image reconstruction, leading to sharper, cleaner visuals. The technology also introduces better motion handling and less temporal instability, which is especially beneficial for fast-moving scenes in games with ray tracing enabled.
Additionally, DLSS 4 boasts an improved capability to handle complex lighting effects like reflections, ambient occlusion, and refractions in ray-traced environments. This makes it a perfect companion for games that push the boundaries of visual fidelity with ray tracing.
How DLSS 4 Complements Ray Tracing
Balancing Performance and Quality: Ray tracing's demanding nature can lead to significant drops in frame rates, especially when using the highest settings. DLSS 4 helps mitigate this by offering impressive upscaling capabilities that allow players to enjoy ray-traced visuals without experiencing a severe performance hit. DLSS 4 improves performance while maintaining the visual integrity of ray-traced effects, making it possible to run games at higher settings and resolutions without compromising the overall experience.
Higher Resolutions with Ray Tracing: Ray tracing at higher resolutions (like 4K) can be particularly taxing on GPUs. DLSS 4 makes it feasible to enable ray tracing at 4K by rendering the game at a lower resolution (such as 1440p or even 1080p) and upscaling the output. This allows players to experience the stunning visuals of ray-traced environments without needing a high-end GPU capable of native 4K rendering.
Increased Frame Rates: One of DLSS's primary advantages is its ability to boost frame rates. With the added computational load of ray tracing, DLSS 4 ensures that performance remains smooth by intelligently enhancing lower-resolution images, keeping the game playable even in demanding scenarios. This is particularly important for gamers who prioritize high frame rates, especially in fast-paced games where smooth performance is critical.
Enhanced Visuals Without Compromise: DLSS 4's AI-enhanced upscaling allows for greater detail and sharpness, even when using ray-traced effects. While ray tracing adds realism to lighting and reflections, DLSS 4 ensures that the image doesn't suffer from softness or visual artifacts that can sometimes occur when upscaling. This ensures that the final output is not only smoother but also crisper, preserving the immersive quality of ray-traced environments.
Does DLSS 4 Make Ray Tracing More Accessible for Mid-Range GPUs?
One of the biggest barriers to widespread ray tracing adoption has been the high performance requirements of the technology. Ray tracing demands a lot of GPU horsepower, which has traditionally meant that only high-end GPUs like the NVIDIA RTX 3080, RTX 3090, or newer RTX 4000 series cards were capable of delivering playable frame rates with ray tracing at higher resolutions.
Is DLSS 4 Worth the Upgrade for Older Graphics Cards?
With the introduction of DLSS 4, mid-range GPUs stand to benefit significantly. Mid-tier cards like the RTX 4060 and RTX 4070, which may not have the raw power to run demanding ray-traced titles at native 4K, can now use DLSS 4 to upscale lower-resolution frames. This significantly improves performance while still maintaining high-quality visuals. DLSS 4, combined with ray tracing, allows these mid-range GPUs to run games at 1440p or even 4K with ray-traced effects enabled, something that would have been unthinkable without the assistance of DLSS.
For gamers with mid-range hardware, DLSS 4 makes it much more feasible to experience cutting-edge technologies like ray tracing without needing to spend thousands on a high-end GPU. In this way, DLSS 4 democratizes access to the next generation of gaming visuals, making ray tracing a more viable option for a broader audience.

Conclusion: A Perfect Match?
In short, DLSS 4 and ray tracing are indeed a perfect match. DLSS 4 acts as a powerful enabler, allowing players to enjoy the stunning visuals of ray tracing without sacrificing performance. By leveraging AI to intelligently upscale images and boost frame rates, DLSS 4 makes it possible for gamers to experience the beauty and realism of ray tracing, even on mid-range GPUs.
As the gaming industry continues to evolve and ray tracing becomes more prevalent, technologies like DLSS will play a crucial role in ensuring that gamers can enjoy cutting-edge visuals without the need for prohibitively expensive hardware. For those with mid-range systems, DLSS 4 might just be the key to unlocking the full potential of ray-traced gaming.
Whether you're playing the latest AAA titles or enjoying a visually-rich indie game, DLSS 4 and ray tracing together make for a compelling and accessible experience that’s only going to get better as time goes on.
