4DO Not Detecting Vsync... Also Jitters

Anyway to enable Vsync for 4DO? I have it on but it’s still tearing for that core. Also the screen jitters sometimes but maybe that’s only when using the high res option of 4DO (the only option). Anyway to get rid of the jittering?

That core is known to have vsync issues https://github.com/libretro/4do-libretro/issues/8

Thanks. Just out of curiousity, do you know if the standalone 4DO emulator has the same issue? I’m not positive but I don’t think it’s with every game. It’s noticeable in Way of the Warrior, though. I don’t think I saw or noticed tearing or screen jitter in Royal Pro Wrestling or Slam 'N Jam '95.
