Having gone back to my old pre 5.4 build Retropie I found I needed to downgrade my Kernel due to glitching graphics. Since I have done this I am convinced that Retropie, especially N64 is still running slightly smoother than it did before.
I'm sorry, can someone please tell me where to change the final settings?
My retropie has tearing all the time, and when I add "dtoverlay = vc4-kms-v3d-pi4, noaudio" to config.xml, I get splash screen and screen saver hiccups.
