FB Neo fighting games get blurry

Retro Arcade Fan

One other quick note. On my backup for 2 years ago, the only line that's different is under [all] gpu_mem=256. Should I add that back in?

no: https://retropie.org.uk/docs/Memory-Split/#raspberry-pi-4

I would remove shader and overclock whilst diagnosing the issue. re: verbose log, note it disappears on reboot. if certainly gets generated on a stock retropie install, so this might be a sign you're running an unsupportable configuration? please fill out https://retropie.org.uk/forum/topic/3/read-this-first

@dankcushions I've turned off shaders and removed all overlocking. I'm trying to record a video so that you can see it, but it's not easy. Will upload after I get one. But I still can't get the verbose log to show up in that folder. I'm launching with verbose logging, playing the game, then exiting the game. I'm not rebooting. Folder only has that one file in it.

Pi Model or other hardware: (B, B+, 2 B, 3, X86 PC etc..) Pi 4
Power Supply used: (If using a Pi) Standard
RetroPie Version Used (eg 3.6, 3.8.1, 4.1 - do not write latest): 4.8
Built From: (Pre made SD Image on RetroPie website, Berryboot, or on top of existing OS etc.. - please provide the filename of any image used) Original image from retropie website modified by me.
USB Devices connected: 2 guns, 1 keyboard/mouse combo
Controller used: 2 dragonrise joysticks
Error messages received: none
Verbose log (if relevant): Can't seem to run
Guide used: (Mention if you followed a guide) None
File: (File with issue - with FULL path) Any FB Neo fighting game (Street Fighter, King of Fighters, Art of Fighting, etc.)
Emulator: (Name of emulator - if applicable) FinalBurn Neo V 1.0.0.03 65cb1c7

At this point, the graphics stutter is so random, I'm pretty sure it's going to be a difficult thing to analyze. I might just have to live with it. What frustrates me now is I can't pull the log you want in an effort to help me out. What am I missing here?

@Retro-Arcade-Fan so is the blurrynes constant or does it just last a second? Is it screen tearing? The pi4 is known to cause screen tearing.

@lostless It's a random blurry stutter of both the fighters and the background. Lasts for about a second. Not life altering but noticeable. Only been happening for a few months.

dankcushions

it could be the classic jitter/stutter issue with the pi4 graphics stack, fixed with kms driver. there's a long thread that i don't have time to parse right now but the instructions are within there: https://retropie.org.uk/forum/topic/25370/good-news-regarding-tearing-and-low-emulationstation-performance-on-pi-4

@dankcushions Thank you! I'll read over that post and give it a shot.

@dankcushions That's a pretty long post. I followed along and the changes on the first section look kind of severe. Not sure I'm comfortable with messing with the kernel. If that's what you're referring to? There seems to be a lot of back and forth of experimentation. Some working, some not. Even for a post a few years old. I want to respect your time, but that post just confused me.

I would like to add a separate question please. In Retroarch under FB Neo the video options are gl, glcore, sdl2, xvideo and x11. Mine is set to gl. Is that correct?

Thank you.

yes, that's the nature of the fix. ultimately this specific issue (remember i don't know if that's what you have as you haven't provided a video) will be resolved with the next bullseye version of retropie, whenever that's available. so i suggest you should stick with what you have, wait, or restart from a fresh image (since you're unable to provide a verbose log, which does imply something fundamentally wrong with your install)

yes, don't change that.

@dankcushions Alright, thank you very much for your insight. I'll keep trying to capture it on video.
