Issue Title: Stutter
Description: Stutter in pitools newer than 144 (= 180, 197, 245)

HMD Model: 5K+
First 3 Numbers Serial: 202
Pitool Version: 245 (also 197, 180)
HMD Firmware: 255
Tracking: 2x Lighthouse v1.0

System Info

  • Windows Version: 10 Home (1909 build 18363.535)
  • CPU: 8700K
  • RAM: 16GB 3800MHz
  • Motherboard: AsRock extreme 4 z370
  • GPU Model: GeForce 2080Ti
  • GPU Driver: 441.66 WHQL
  • SteamVR Version: not beta (1.9.13)
  • Oculus Version: none
    I don’t use any additional software for LED control.
    I have tried changing USB ports.
    I tried changing CPU affinity with Process Lasso.
    I don’t use Smart Smoothing and FFR.

There is visible stutter in image displayed in HMD panels.
The stutter is very annoying, distracting. Every pitool after 144 has the stutter. It is game independent, the stutter is visible even in the basic play space in steamvr, when you start steamvr and there are the circles on the floor and ceiling. It is also visible in pimax home (the starter pimax screen).
There are many posts about this in threads about pitools 180, 197.
It seems that it started after pimax changed something about the gpu utilization bug in pitool.

What is pimax doing to fix the stuttering ?
When is this going to be fixed ?

System Info

  • Windows Version: 10 Pro (1809 build 17763.914)

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 :frowning_face:).

I have two pcs that exhibit this issue so I’ll list both.

System Info 1

  • Windows Version: 10 Pro
  • CPU: Ryzen 5 1600
  • RAM: 16 GB 2666MHz
  • Motherboard: Asus prime A320I
  • GPU Model: GTX 1080 FE
  • GPU Driver: 441.66 WHQL (always used the latest NVIDIA WHQL drivers)
  • SteamVR Version: not beta (1.9.15)
  • Oculus Version: latest oculus version

System Info 2

  • Windows Version: 10 Pro
  • CPU: Ryzen 5 3600
  • RAM: 16 GB 3000MHz
  • Motherboard: MSI B350 gaming plus
  • GPU Model: RTX 2070 Super
  • GPU Driver: 441.66 WHQL (always used the latest NVIDIA WHQL drivers)
  • SteamVR Version: not beta (1.9.15)
  • Oculus Version: latest oculus version

The issue occurs on build 1 - which is a brand new pc and nvme ssd. No previous pitool installations, no RGB software (it is a mini itx build after all).

I have had the issue on my primary PC, build 2, ever since i updated beyond .132. The stutter displays itself almost as a tracking anomaly, or a vsync issue.

Follow-up to my previous report:

Date: 2020-01-22
Issue Title: Stutter
Description: Stutter in pitools newer than 144 (= 180, 197, 245)
Pitool Version: 254_alpha
HMD Firmware: 262

GPU Driver: 442.01

  1. Thank you for the new pitool. I installed both new pitool 254_alpha and firmware 262.
  2. Unfortunately for me the stutter is still there. It is a bit better than before, but it still stutters. (but it helped to some other people)
  3. I tried Pimax Home and SteamVR starter space = stutter
  4. I tried disabling lighthouse tracking, but it did not help = It stutters even with the internal 3DOF. (I thought lighthouse tracking could cause the stutter)
  5. After installing pitool 144 the stutter is gone again (keeping the new firmware 262)
