This is a simple, small app -- ~3MB download -- to toggle/reset ULPS/MPO/TDR/HAGS/SHADER CACHE.
This rig uses an AMD 5700G I bought so I could give my son my graphics card during the height of GPU pricing insanity. Later I bought an RTX 6600 -- my needs nowadays are minimal. I always update/use the latest graphics driver. And since I got the 5700G I've suffered intermittent system freezes due to graphics driver memory issues that continued when I installed the RTX 6600. Using this tool to turn off MPO seems to have fixed it -- it's been a couple of weeks so I could make sure before recommending it.
