Is there anything else I can do to increase the emulation performance of the Raspberry Pi, running RetroPie?
I’ve overclocked it, I’ve switched to the generally better regarded emulators like PiSNES. I read somewhere that someone forced 720p instead of running in 1080p to get better performance. Would that be beneficial? If so, how would I go about doing that?
You can edit the /boot/config.txt file to have the pi running in lower resolution. I’m not sure if it’s just the CLI that run in lower res though, I have mine set to 1280×720 and I haven’t seen any performance differences worth mentioning but the CLI text is readable now. I get full speed in Snes games though with the CPU clocked to 1000 mhz, without using shaders.
As refrofredde said try go in into the config.txt and changing the resolution to a lower scale. Mine is set to VGA mode at 4:3 aspect ratio.

Cheers. Working non-stop all weekend, but I’ll give it a crack on monday
You could optimize some files. I don’t know if performance increases.

I have only tested pocketsnes and retrarch core. Delete RetroPie/emulators/RetroArch and RetroPie/emulatorcores/PocketSnes and do a source based installation.
