What is normal CPU/GPU Usage?

[spreckair]

I am playing on an Intel I7 11700K with 32 GB RAM, RTX 3080, and HP Reverb G2.  My CPU usage is about 15% to 25% with temps at around 47C; my GPU is around 100% with temps around 51C.  Does anyone know if this usage is normal?  I am wondering if the CPU usage should be higher?  Also, my FPS is stuck around 45 FPS. 

 

I used to have an Intel I7 10700K with the same RAM and GPU, and it seemed to perform a lot better, with FPS in the 70 to 90 range.  This has me scratching my head.

 

Thank you.

Your CPU usage is normal. But depending on scene (dense scenes) your CPU could the bottleneck even if the CPU usage is at 15-25%.

 

Your  CPUs has 8 physicall cores and typically the overall CPU usage is the average of every individual core usage.

IL-2 has several threads running in different cores. There is one or two threads which are very heavy and they jump from core to core, so you will never see an individual core at 100% always. So, the information of CPU % usage has little value for IL-2.

 

The GPU % usage is more instructive since it really tells you how bottlenecked is your GPU.

The G2 is quite demanding in the terms of total number of pixels. At 100% Supersampling is 19.5 million of pixels at 90Hz. And a 3080 is not powerfull enough.

You will need to decrease  %SS, clouds details and MSAA in order to keep the GPU usage below 100%.

 

There is an app quite useful to tune your settings: fpsVR

@chiliwili69  Thank you so much for the info; I am so inexperienced with this stuff.  I will check out fpsVR.

After scouring the world-wide-web for a couple of hours, I was able to find an old post that described the settings to get a consistent 90 FPS with the HP Reverb G2.  Those settings produced poor visuals, but with minor tweaking, I am now getting 80 to 90 FPS with nice visuals once again.  And my rig is running cool.  Sigh.
