Simple dumb question-

I’m trying to setup Retroarch on a Low-end PC with 800x480 resolution on full screen. My problem is how do i setup the proper AR for cores up to PSP?? Right now is set on core provided and on 4:3 the seemed a little bloated and on 16:9 a little squished. Also theres screen tearing. I’m really bad with these settings on RA. Sorry

Please help

With that low of a resolution, you’re best off setting the AR to 1:1 PAR, otherwise you’ll get really bad pixel warp/shimmering

Got it, Thank you. What can i do to reduce the screen tearing and flickering that i´m getting without impacting performance?

Pretty much just making sure vsync is on. If it is, you shouldn’t be getting any tearing.
