This is a really great mod. I have tried it in both Ryujinx, and Yuzu, and found that with Ryujinx there is constant micro stuttering (even though I get the advertised framerate).
Having said that, my rig isn't capable of sustaining 60FPS in either app. As a matter of fact, I am not capable of sustaining 30FPS in Yuzu at normal resolutions (I have I7 and RTX2070), but.... If I bump it up to 4X docked, I can maintain 30FPS all day long (except when coming out of a manual save). Pretty odd for sure!
For those Ryujinx users wanting to simply get 30FPS, the 30FPS mod isn't necessary. If you turn off Windows Hardware Accelerated GPU Scheduling in Windows settings (it is on by default) the game will play at 30FPS naturally.
