I was only able to play skate 3 so far with better performance than rpcs3. I didn’t change any settings in the conf file. It is using the vulkan renderer.
I limit the fps to 30, TPD to 8 and GPU to 1200.
I’m trying a few games here and there to see but It can only improve over time.
Have had it set up on the deck for 6 months but not with emudeck. The xbla leak of Goldeneye 64 with the community fixes is great. It’s better than the releases for switch or the recent Xbox one.
