Pimax 5K Plus stutters *solved*



I got this issue suddenly after almost everyday use;
When I open Pitool home Pimax starts constantly stuttering when moving head. Usually stuttering begin immediately but sometimes in couple minutes. When I keep head steady all is fine but turning head causes lag. When trying iRacing I have same lag and FPS is around 80 (usually locks to 90).
I use Pimax without any external base station. What I have tried so far;

  • Changed usb and dp ports
  • Reinstalled all drivers
  • Reinstalled windows
  • Tried Pimax in different computer (works fine)
    Any suggestions what to try next?


Disable any background monitoring application and/or LED/RGB control software like Asus Aura both of which may be hogging the USB controller(s).

Set Windows power management profile to ultimate performance and Nvidia power profile likewise.


Can you post your system config?

Windows Ver
Gpu & driver version
Pitool version



What’s your Steam SS rendering set at? Not % but actual resolution. You can click custom if it is not set to see what Steam has selected.
Try lowering it to 2700ish horizontal and see if it still stutters.


Last time when tested SteamVR wasn’t installed.
Today I will make clean installation of Windows, I used Windows own recovery tool last time.
Let’s see if it helps.

Thank you. I disabled aura from bios and it seems problem is now fixed.


Nice. You’re welcome… :+1::wink:


@Doman.Chen the team will want to look into this issue conflict with Aura sync.


If you enable it does the issue come back?


Yes, the issue came back instantly.


Thanks I passed the info along to the team.


Should find details from other user. As this issue is not affecting all Asus Aura sync MBs.


For me all I did was uninstall the Asus Aura software do it seems to be the software polling the LED controller (?) causing issues and not having the LEDs on.
