Could you recommend a good & cheap HDMI Touchscreen which works for RetroPie?
from 3.5inch up to 5inch would be nice (with Case).

Thanks in advance!"

@Xyb0t said in Performance boos due to lower resolution??:

@dankcushions Well, i understand that scaling might not mean a lot, but rendering i guess will take it's toll??

they're the same thing. you can't 'render' a NES game in a higher resolution than 240x224 (or whatever it is natively). a higher render resolution just means it's scaled to that by the GPU. same with psx, etc.

(with shaders it becomes different)

How can i test for myself? Is there some form of on-screen FPS counter that i can switch on?

select + x to get to the RGUI. settings > video > show fps counter.

@windale
I recently played through Robocop using lr-fbalpha (0.175 romset) and I didn't notice any speed issues (but I'm not sure if I would noticed 57.4 vs 60 on that particular game). I am interested to see if anyone knows how to change the refresh rate in Mame2003.

@mrbwa1 I know, but when you turn the resolution down, people claim it works. I'll use a display with a very low resolution so I'm fine with turning the game's resolution down. But thanks anyway :)
