Did a clean install of Pitool 245 (uninstalled old version, rebooted, deleted Pimax folders under C:\Users\user\AppData\Local, LocalLow, Roaming and C:\ProgramData, and installed new version).
Not using any RGP LED control software. Have tried changing USB ports. Tried changing CPU affinity but this does not help. Not using Smart Smoothing or FFR.
There is visible stutter seen in games, Steam VR test screen, the Pimax home planet scene etc. The stutter is very annoying, distracting. Every pitool after 144 has the stutter.
The stutter is visible in all refresh rate modes eg. 90Hz, 72Hz and 64Hz (currently no 120Hz available for the 5K+ S/N 202* owners
).
