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?retrofreddeParticipant02/13/2014 at 09:41Post count: 34
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.kitchukParticipant02/13/2014 at 18:08Post count: 207
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.kitchukParticipant02/13/2014 at 18:08Post count: 207

Cheers. Working non-stop all weekend, but I’ll give it a crack on mondaygizmo98Participant02/17/2014 at 19:18Post count: 452
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.
