Having issues after installing a (new) gpu in your system?

Then this is the tool for you!

Here's a list of symptoms caused by MPO (a feature added by Microsoft a few years back):

  • Stutters when tabbing out of games (multitasking)
  • Driver crashes/System hangs when using hardware accelerated browsers
  • Driver crashes/System hangs when trying to stream
  • Anything fullscreen would cause huge stutters and can lead to crashes and hangs
  • Screen flickering nonstop

List of GPU affected by MPO as reported by users:

  • NVIDIA RTX 40 Series
  • NVIDIA RTX 30 Series
  • NVIDIA RTX 20 Series
  • NVIDIA GTX 1600 Series
  • AMD RX 5000 Series
  • AMD RX 6000 Series
  • AMD RX 7000 Series
  • And maybe more!

Why did I make this tool?

Because I was also plagued by these issues and found out about MPO 2 weeks after enduring pure torture of having a decent pc not being able to do jacksh**t. So I decided to help everyone out by making the process a lot easier. I know that NVIDIA released Reg files to disable/restore MPO, but I wanted to make a user friendly experience. Also because I got time on my hand during winter x')

MPO-GPU-FIX

This small and compact tool disables MPO on windows that causes issues with GPU Drivers. Check out the WIKI for more info: https://github.com/RedDot-3ND7355/MPO-GPU-FIX/wiki
