Heavy N64 lag after reinstalling

EmK530

I had accidentally made my Pi download a GL driver just by exploring the settings of raspi-config which made it lag heavily in N64 games so I went to reinstall and when I did it was still very laggy, the games menu lags and the N64 FPS goes very low and there's visible screen tearing, even games as simple as the title screen on Mario Kart 64 has lag, I've tried switching emulators. Running vcgencmd get_throttled through SSH just returns 0x0

(I have not yet tested other intensive consoles, I was too desperate to fix N64, Only other thing I tested was GBA which worked)

(Looking in top/htop in SSH shows that mupen64plus is using a peak of 40 percent CPU but I don't know how to monitor the GPU)

Version: 2.7.1 (recent version if this is wrong)
Model: 3 B+
Power Supply: Official Raspberry
(Don't really know about what info I should add so just ask me in the replies)

Accidentally ? If you used raspi-config to enable the GL driver, then use raspi-config to disable it. Post your /boot/config.txt configuration file.

Version: 2.7.1 (recent version if this is wrong)

Most likely 4.7.1, this is the latest tagged release.

@mitu EmulationStation refuses to boot anyway with the GL Driver enabled so it's disabled.

Will give more info when I get home

Noticed that scenes that would make it lag way more actually doesn't lag it that much more at all, which makes me thing it's being limited by something but I have no idea what it could be. Hopefully that helps a bit

@emk530 please post your /boot/config.txt as requested

you won't be able to give a verbose log as you're not using a retroarch emulator. however you can still get a regular log in /dev/shm/runcommand.log that will be useful

mupen64plus-gles2n64

i wouldn't recommend using this - it's not the default. mupen64plus-gliden64 is most compatible.

EmK530

@dankcushions mupen64plus-gles2n64 is fastest for me but if you have a solution I could switch what I mainly use

Coming with runcommand.log as fast as I can

EmK530

@dankcushions Can't find a way to get the runcommand.log,

pi@retropie:/dev/shm $ dir
pi@retropie:/dev/shm $

Tells me nothing

Edit:

Saying again, scenes that should make the emulator lag way more actually doesn't lag it much more at all making me think there's something limiting it or something else

@emk530 did you run the game since your last reboot/reinstall? it will always populate it.

sorry, just seen you're using pi3 - gles2n64 was historically good for me for mario kart on the pi3, just not with the mesa driver.

it's definitely normal for a pi3 to lag quite a bit on n64, though. for mario kart 64 it would be normal for it to lag a bit at the start of the race, but should be mostly smooth during gameplay. how does the lag manifest in mario kart?

mitu

@emk530 The log file is created after running the emulator. Since /dev/shm is kept in RAM, you'll have to get the file immediately after exiting the emulator and before starting another game.

@dankcushions Let me provide a video if you give me some time

Played on gliden64 as requested

@dankcushions Lag is kinda the same in every scene in the game. No idea why.

Sorry for the weird background noise, I don't know what went wrong

PROBLEM SOLVED:

I downgraded to version 4.6 and it's running just fine

tuomaspap

@emk530 I upgraded to latest 4.7 and having exactly the same issues with you but on the Pi4.
Can't find the image of 4.6 though anymore :( Is there somwhere you got it from that you could share link ?

EmK530

@tuomaspap Sorry for the delay, I never expected a reply. I was able to get it through the wayback machine. I've gone ahead and found a link on github for the pi4, hope it works!
