Why isn't there a change in fps when adjusting the resolution in CS:GO?
Hi. I use cs at 200-450 fps with a gtx 1650 gddr6 oc i3 10105f and 16gb ddr4 3000mhz. When testing new resolutions, changes were minimal—going from 1280x1024 to 640x480 dropped about 10-15 fps. I’m now upgrading to a 1080p 144hz monitor and wondering how much fps will decrease. I expect around 20-30% loss. I’ve heard that if FPS stays similar, it might not be a bottleneck, and in most games both GPU and CPU perform well together. No one’s reported maximum issues. Any advice from someone who upgraded their monitor without changing the PC? Thanks ahead.
Happy New Year!
Your GPU will manage eSports titles smoothly, but you may notice some issues on a 1080p display. If you're not seeing much improvement, try reinstalling your GPU drivers. Use DDU to clear all GPU drivers, then manually reinstall the driver from Nvidia's support site with administrative privileges.
Higher resolution demands greater processing from the GPU. To address this, understanding your current GPU utilization at present resolution is essential. A rough estimate suggests that if GPU usage stays under 60% at 1280x1024, you should maintain consistent FPS when increasing to 1080p (provided there’s no VRAM limitation, which shouldn’t occur in a game like CS at lower settings). Keep in mind, other factors beyond pixel count also play a role.
According to math, you should expect about 250-270 frames per second at 1080p resolution. This is based purely on pixel count without considering other variables.
What is your cpu?
If you get no difference in performance when you change resolution or settings, it is an indication that you are cpu limited.
I think csgo is very cpu intensive and is also a single threaded game.
Be careful about interpreting cpu usage %.
A single thread could be 100% busy but the cpu usage would be only 25% on a quad core processor.
Also realize that cpu processing and gpu processong are not necessarily concurrent.
Run the cpu-Z bench and look at the single thread performance rating.
If, for example you were using a I7-4790K you should get a number like 469:
