You purchased a brand new graphics card from AMD or Nvidia, however, after installing you find that the new GPU is not working properly or not as fast as you expected? In this article we’ll share some useful tips on how resolve this issue.
Fix new GPU is overheating quickly
Why your new GPU is overheating quickly? Well, the GPU and the CPU produce heat when they work. The fans then start to work under load and remove the heat out of your PC so that the GPU does not get too hot even under load.
However, if your PC is not properly ventilated then the heat will build up inside your PC and this will cause your GPU get too hot. If the GPU gets too hot, it throttles its performance in order to generate less heat in this way.
Another reason for high temperatures is contamination of your PC by dust or animal hair.
Power supply is too weak to handle
A common problem is that gamers equip their PC with a new, powerful graphics card, but forget the power supply unit at the same time. Because fast GPU often need more power from the power supply.
Even if you have the latest GPU in your PC, performance can be limited by a power supply that is too weak. In the most annoying case, your game or even the entire system will crash.
How to fix this issue? The simplest solution is to buy a new power supply that offers enough power for your gaming PC.
Too little VRAM
If you play in very high resolutions (WQHD, 4K) or VR games, then the VRAM is heavily used. No matter how fast your GPU can be: if the VRAM is full, then there are unsightly texture loading errors.
This applies above all to old high-end GPUs, which officially deliver more than enough performance for current titles, however the too small VRAM quickly limits.
How to fix it? The best way to solve this issue is to lower the resolution of the game and thus the memory consumption of the GPU. Some games also offer you the option to limit the graphics card based on the graphics memory.
Faulty or outdated software or drivers
Faulty or outdated software can also affect the performance of your GPU. Manufacturers such as AMD or Nvidia regularly provide new software updates to fix errors.
Even a severe crash can damage software that was working until then. A clean reinstallation often helps here.
How to fix it? You should reinstall the software you suspect. If you reinstall your GPU driver, you need at least one restart for the changes to take effect. In the best-case scenario, the problems will disappear after a software update.
Your PC hardware is too weak for your GPU
You install a new high-end GPU for your PC but still have your old low-end processor and 4 GB of RAM installed.
Other hardware can also affect the performance of your GPU. If the CPU is running at 100% utilization but the GPU is getting bored at 10% utilization, that's a good indicator. In technical terms, this is called the "bottleneck": In this case, the processor is the bottleneck because it simply cannot provide enough performance to keep up with the GPU.
What can you do about it? If your other hardware is too weak, then you have to consider in the long term whether you don't want to upgrade the other hardware such as the processor, RAM, etc. Otherwise you will not get rid of the problem easily.
A short-term solution would at least be to lower the graphics settings and thus reduce the strain on the bottleneck. But that doesn't change the fundamental problem that your graphics card cannot be fully utilized.
