Set the display to 800x600, but no dice, it seems like it possibly won't display at that res. Everything still says 640x480 (fbset, tvservice)

So i've turned off integer scale, and that did the trick. It's not exactly perfect, the pixels are a little fuzzy. But it's acceptable for now until I figure out more stuff I can try with the Pi config.txt stuff.

Thanks for the help!!

@iggy said in Overlay scale setting messed up:

Load a game and then enter the retroarch s

Hey iggy, hust thank you so so so much, you explained everything so well and it works grate :D

Thanks :D

Emulationstation accepts the --screensize <width> <height> parameters so it might work to start it in a viewport without mocking with the overscan bands on the display. This, in combination with the RetroArch viewport settings, might enable you to run everything in a custom viewport.
Of course, you might have trouble with console script (i.e RetroPie Setup or any other scripts) and with non-Libretro emulators.

EDIT: you might need to also add --screenoffset <offsetX> <offsetY> in addition to --screensize to position the viewport.

Re. speed gains :
What about running games at low resolutions, but then using shaders to make it look acceptable? Or do the shaders always run at the emulated resolution?

I installed Xfce. Scaled fonts, icons and cursor. Looks a bit odd, but it works. Emulationstation, kodi and the desktop are all accesible from the couch :)
