I did consult the forum on Frame Rates but no answer to my specific question. I assembled a new system just for the new FS. Ryzen 7 3700 X, Asus Geforce TUF 3060-ti O8G, Corsair Vengeance LPX 32GB RAM 3000Mhz, Mainboard Asus Roge Strix X570-F Gaming, Dell 2721 D 1440p with G-Sync Ultimate.
Initially I run the FS on a Full HD Monitor. I achieved FR of around 50. CPU Main Thread was limiting. I upgraded the processor to Ryzen 7 5800X. Frame Rates went up to 60. GPU and main Thread were flickering alternatively limiting. V-Sync was on.
Now upgraded to 1440p Monitor with G-Sync Ultimate and HDR enabled. Ultimate Details Setting in FS.
Frame Rate dropped to between 40 and 50 in Ultimate, in High 10 Frames more.
GPU is limiting.
GPU is running max at 25%. Memories with lots of Headroom. GPU Temp at 65 degrees C. CPU below 60 degrees C.
Why is the GPU the limiting factor if its underutilised?
Thanks for your help and insight.
How can the GPU be the limiting factor if its only used 25%
Task Manager GPU usage is unreliable, there have been lots of people showing usages of 8-25% where in fact the actual usage is 60%-100%.
Try GPU-Z or MSI Afterburner or HWiNFO64 to check the actual GPU usage.
So do you need to show all of: 3D, Copy, Video Encode, Video Decode, Compute_0, Legacy Overlay, Video Processing, Copy 1, Copy 2, Security, Graphics_1, Cuda, Compute_1, VR, Copy 3, Copy 4, Copy 5
… and add them together manually? Naturally what you want it to show the majority of the time is the actual activity of the CUDA cores or equivalent.
Important is which engine is used, you can check the mentioned MS Blog if you follow the links.
As example: If I record a video then the video-encoders are used which are abolutly independend of the other GPU engines like 3D renderer, 2D stuff, CUDA cores as you mention it, etc…
you mixed you the topics… what shadowplay show you ( which window it have in focus ) and the GPU load.
Again… I gave you a link to another thread/post in which a image exactly show you where you have to click that you see the real GPU load. Have you done/tried it ?
EDIT: for your the example with your postet image:
use the tool from xbox game bar. This tools will show you the usageof your cpu, gpu and all memories … it is more realsitic than the task manager … On my task manager, I only use round about 8 % of my gpu … I have a 3090 …

you changed from an HD monitor to a 1440 with HDR, this is likely the reason your frames dropped, you’ve increased the resolution that is being outputted to be displayed. Test it out on your old monitor and note the frame rate, plug back in your 1440 and note the new frame rate.
I get 70fps on my old 27inch 1080, i’m getting 27 fps on my 49 inch 4k. The higher the monitor resolution the lower your frames will be.
