Pi4 and shaders performance?

dovik

Hi all,

Pi3 is great and allow to emulate tons of game.

But it can’t be used with retro shaders at fullspeed and is sometime unplayable with retro shaders.
(try “WarioWare Inc.” or “Rythm Tengoku” on your GBA then try it again on Pi3 with retro shaders to have a definition of unplayable).

Pi4 owners: Has Pi4 better performance with retro shaders? Less lag?

Thanks

I’m currently on Recalbox and not on Batocera, but here’s what it can do with shaders. It will run only the simplest ones (fakelottes, crt-pi, zfast are the ones I found interesting). Some others will run with a GPU overclock, sometimes massive. sameboy-lcd-gbc-color-motionblur works for GBC, GB and GBA with the GPU at 850 MHz, have to remove motionblur for wonderswan because it runs at 75 Hz.

All in all, I’m satisfied with fakelottes for anything that used to run on CRT that is 2D and sameboy for my LCD handhelds. They’re far from the best looking ones, but they work. My screen is atypical but has 1.1 Mpix, so those that required an overclock probably won’t run at 1080p.
