Here is the Verbose log while getting the stuttering. I am no expert so hopefully this is what you were looking for. https://pastebin.com/6rJFgXQb

The log seems incomplete. It seems you're running RetroArch 1.8.4, but the 4.6 image has been released with v1.8.5 - are you running the image from retropie.org.uk/download or another image ?

@Quackwalks You should create your own topic.

@yman Thanks. These files seem incomplete as @mitu stated.

We're looking for:

/opt/retropie/configs/all/retroarch.cfg
the log you sent, but after starting the emulator with "Launch with Verbose Logging" in the runcommand menu. So, when launching the game, press a key when the dialog shows to open the runcommand menu, and then select the option for "Launch with verbose logging". Then play the game for a while.

Thanks.

For videos, I use YouTube, I don't really have better recommendations, apologies.

[INFO] [Overrides] game-specific overrides found at /home/pi/.config/retroarch/config/Snes9x/Super Mario World (USA).cfg.

you should also show us that override

Retroarch.cfg

retroarch.cfg from where? this does not look complete/standard. you should show us the one in /opt/retropie/configs/all/retroarch.cfg and /opt/retropie/configs/snes/retroarch.cfg (as well as any core/game overrides being applied, such as the one i referred to above).

Issue on prebuilt and stock retropie image

be mindful that that we ONLY support the stock retropie image and it should be very obvious if you're running a third party image if i see the config files. please make sure you do your testing on the stock image.

@mitu I mistakenly took the wrong log. This one was from a non stock imagine. I am getting the same issues with the stock image. I will post this Log and everything else requested above as soon as I can. Thanks

@yman Could you check my post and tell me if my problem looks the same as yours. https://retropie.org.uk/forum/topic/26819/jittery-stuttering-graphics

yman

@Quackwalks this is exactly what is happening with my setup. Any luck fixing it ?

Quackwalks

@yman Check out my post. There's been debate on whether a setting called gsync really solves the problem or just appears to remedy it somehow. It's worked for me but I needed to make sure it's not enabled for n64 to have smooth game play.

Have you guys tried upgrading to the 5.4 kernel and then switching over to the vc4-kms-v3d (full KMS) driver in config.txt? I saw one mention of it here, but would be good with more data points to determine if it affects the issue at all.

@Brunnis I just tried this but my tv says it's an unsupported resolution.
