I had the same problem with Pokemon moon. I solved it by disabling hardware acceleration.
turning off hardware acceleration did work. Now its running on only 30% speed. Not playable like this. still need help to fix the issue
okay, so I managed to sit through the tedious opening sequence and turned on hardware rendering when I moved out of the house. I checked the detailed(?; sorry, just roughly translating from german) multiplication and geometric shaders. Works fine so far
You don’t need to turn on Accurate Multiplication for UM. Leave it off.
Another possible solution to this is possibly only needing to turn of hardware shader. It works for me, and doesn’t majorly slow down the entire game.
