[quote=95087]@all check if your video_fullscreen_x/y settings are 0. Otherwise your resolution will be upscaled. Hardware upscaling should be default enabled for rpi1 performance reasons.
There will be a performance drop if you use a HD resolution with shaders.
Actually, I was wondering about this. I thought that since the RPi1 and RPi2 had the same GPU that they would be able to run the same shaders. Is this not the case, and do you know why not?
So far I have not had any performance issues with my monitor set to 1080p and Retroarch’s render resolution at 720p on an RPi2.
