Slow and glitchy sound and gameplay on mac M1- Ventura - version 2.3.3

Open arrfonseca opened this issue 2 years ago • 7 comments

Hello there, I'm on version 2.3.3 and experiencing slow performance and glitchy sound in all emulators. I'm playing SNES, for example, and this is present in all games. I noticed that when I change shaders the glitchy sound and slowness just go away for a fraction of a second. Any ideas on how to fix it?

I'm experiencing this similar issue trying to play "Policenaunts" on PS1. I'm using a M2 MacBook Air w/ 16GB Ram and on OpenEMU version 2.3.3 as well. Sounds and video stuttering constantly.

So, tried it again today and it worked fine. Maybe I just needed to completely restart my system then load it up to get it to work properly.

So I was having a very similar issues on my new 2023 14" mac book pro with the m2 max running openEmu 2.3.3 . I searched the forums for a bit and someone recommended changing display settings. Sure enough, it was my pro motion display refresh setting that was causing the glitching. Pro motion on the new displays is 120Hz. I dropped it down to 60Hz and bingo game ran PERFECT. I changed it back to Pro Motion and the problem came right back. The old games were never meant to refresh that quickly and I'm sure a clock signal needs to be adjust in the code when running at greater than 60Hz. So for anyone having this issue make sure the display you're running is 60hz or less.

@perronj2 same thing here with MBP M2 10c 16GB. Even with external monitor at 120Hz. Just downgrade from 120 to 60Hz or use my second monitor that is 60Hz

Confirmed: disabling ProMotion and locking refresh rate to 60Hz fixes the issue

Out of curiosity, has anyone identified some path to a better fix for this?

Is there any fix for It? I run my monitors under HDMI cables so their refresh rate tops 30hz. Still have the same issue.
