So I discovered that if DS4Windows executable is running then I have a performance loss on retroarch, which is pretty surprising given that DS4Windows doesn’t seem to consume any meaningful CPU time according to task manager.
I have tested snes9x current and Beetle PSX cores, and both suffer a pretty hefty loss in performance, snes9x being affected harder.
I test by toggling fastfoward on and then just taking note of how many fps I get in this mode.
I got this version of DS4Windows https://github.com/Ryochan7/DS4Windows
Here’s some screenshots:
