Pimax 5k+ 1080ti 70% utilisation in Project cars 2

[Ritz]

Hi folks,

I’ve noticed my gpu constantly hangs around 70% utilisation and fps is not going far from it so its around 60-74fps. I had more fps on some old pitool but I’ve lost it.
If I apply catalyst utilisation jumps and so does image doubling up/splitting differently for left,right eye/ weird chroma and stutter. So as you realise I am keeping it at default.

Is there any fix to all this? I have this issue almost in all titles I play Dirt2/PC2.

Specs:
Pitool: V 2020.3.24
Headset: 255
Cpu: Ryzen 2700x
Ram: 16gb 3200Mhz Cl16
Vga: Palit 1080ti gamerock
SSD: Samsung 950evo+ 1tb m.2
VR: Pimax 5k+

Welcome to the Open[color=orange]MR[/color]!

There has been a few members revert to I think it is 255? As the GPU catalyst versions didn’t work well for them.

Seems often pitool releases have mixed results.

@Ritz Pitool .254 has the best performance, but has crashing issues amongst other things. Try .253, its the ‘fastest stable’ pitool. For me it is unusable due to stuttering, only .255 or .258 are acceptable for me, but if you don’t get stutters, .253 is the pitool to go with for right now

Thanks - got .253 - fps now hovers around around 65-78fps, utilisation is 88%-91%. Plus applied a sharpening info from another user in this forum. Now I have clearer image and more fps. It’s a Win for me sharpening info - https://community.openmr.ai/t/project-cars-2-pimax-5k-8k-setup-guide/14818

I’ve changed line in config to **prop name="SharpeningStrength" sharpeningstrength="0.500000"/** since value 1.1 was way too much for me
