Jittery/Stuttering graphics
-
@greenhawk84 that setting comes with a performance penalty. Its been a while since I tested it but I remember certain games taking a noticable dip in performance.
-
@quicksilver not sure if I notice a performance dip but this VRR option is the cure for the jittery/tearing anomalies in certain core/game combos. I really think something changed but I am not technical enough to pinpoint that. I am surprised since our hardware is the same if we're talking Pi4, that more people aren't seeing this issue.

Hello, just wanted to comment that after a recent update, I think the issue I was seeing has resolved. I disabled Runloop_vrr and it was the same as it was enabled. Not sure if perhaps something was changed but I did notice Retroarch is updated. Can't speak for everyone if this was the same as screen tearing but I wish I could show you all what I was seeing on some games. I will monitor this and mention anything if it happens.
-
Welp, I did a routine update just now, and the issue has returned. Enabling runloop_vrr is still the fix. Man, I wish I could somehow capture it, but it really does take an eye to see it.
Mame2016 running Metamorphic Force, sprites tearing/jittering was my example.

I know this is an old post, but this is still an issue and my search of the forum didn't return any better results, so I'm necroposting this.
This issue is still occurring big time for me. I've been having issues since putting RetroPie on my Raspberry 4 and I haven't been able to find any resolutions. I have:
vrr_runloop_enable = "true"
Set in retroarch.cfg under /all. I've tried a bunch of different VSync settings, I'm seriously just about to reformat and start over but that's such a frustrating process... and I don't even know for sure it won't persist. I just updated my RetroPie recently, but I don't know what else to try. I'm not super savvy with the Pie settings, but I can follow instructions well if anyone has anything else I can try.

@TeeEl can you please share more details according to the forum post guidelines? Also specify your hardware (monitor), emulator and game. If you have a video, even better.

@TeeEl I will chime in here as this is something that's been bugging me for quite some time as well, without answer. After reading this entire post, my personal solution was turning Sync to Exact Content Framerate to on. This actually solved my "screen tearing/stuttering" in my fbneo fighting games like Street Fighter.

@Retro-Arcade-Fan I had tried that as well, with no success.
@pjft I'm using a 77" LG CX. The issue happened OUTSIDE of any game (in RetroPie there was visible tearing) as well as any game I tried... but Dragon Warrior 4 was hands down the worst that I saw. And honestly I got so sick of the issue I just reformatted my SD card and I'll be trying Lakka instead. It seems much less user friendly already, but I'll take that if I can play my games unimpeded.

@TeeEl said in Jittery/Stuttering graphics:

Most likely the stuttering happens because you're running at 4k@30hz (default on a RPI 4). Disable 4k and run at 1080@60p and things should be much smoother. See here for how to do that.

@TeeEl Sorry to hear that. My arcade cabinet has a 32" tv, but the problem started for me a few months back. But I couldn't pinpoint exactly what caused the change (I already had a similar post about it). Thankfully for this post, I was able to find an option that worked for me. I hope you do too!
