PiTool 262, excellent performance: can’t crash the frame rate. Did anyone else experience this?
In Elite Dangerous (ED), I suffered late CPU starts (minimum 3-4ms up to 6-8ms looking at SteamVR Performance Graph) throughout all PiTools versions in Windows 1909/2004, leading to stuttering on anything else other than ED absolute minimum settings.
Running an i9-7900x, 32GB, 2080Ti, Pimax 8K (normal FOV, 72Hz and rendering quality 1.0), SteamVR at 100% and ED at absolute minimal settings, the VR-performance was simply unacceptable to use.
After way too much tinkering to get ANY combo or Windows10 (1909 and 2004), PiTool, SteamVR and Elite Dangerous tuned for good performance (or any for that matter), I put my Pimax 8K on the shelf. Next, I dusted off my old HTC Vive to use. No late CPU starts, a great VR-performance and I enjoyed my Vive for a few days. Piss poor FOV though!
Tinkerers by nature, right? The Pimax 8K ED poor performance kept bothering me. What did I miss? Enjoyed the Vive, but I wanted my 8K to work well before the 8KX would arrive.
Saw PiTool 262 release online.
I reinstalled Windows 10 2004 from scratch with Steam, SteamVR and Elite Dangerous. For testing purposes, I left everything at default (untouched, no alterations). Made a system-clone for re-use later.
Installed PiTool 262 and used the Pimax 8K. Again, I left everything at default (untouched, no alterations). ED gave me a stunning performance, so I tried to push to see how far I could go:
nVidia Panel Settings: let application decide
PiTool: rendering 1.0, 72Hz, normal POV
SteamVR: SS at 100% (manual override)
Elite Dangerous: except Shadows (Low), Ambient Occlusion (Off), Galaxy (Med), all other settings at max setting with HMD quality at 1.5.
I can’t get the thing to crash below 72Hz: foggy space stations, loaded RES, complex planetary bases and hazy mountainous terrain are all running smoothly without a single frame drop (CPU 3-8ms, GPU 4-12ms). Confused the hell out of me.
So, I decided to test it out. Restored the Windows 10 2004 made earlier and ran each PiTool (250’s up to and including 261beta) for testing. No joy: high CPU usage, late CPU starts, GPU underutilized, you name it. Basically unusable. I installed PiTools 262 and it’s completely smooth, not a single frame drop. CPU usage is lower than before (NO late starts at all) and the GPU is now properly utilized (60-98%).
Pimax, I don’t know what you did, but you did a great job. Seems your new, built-in GPU optimization works well! Thank you. You made my 8K a fantastic kit again.
