[quote=98549]In terms of a guide for this one, do you just select that shader, or did you specify a new viewport setting as well etc.. ?
I think you had this in your original guide, but have deleted it now to show the overlay details instead?

I guess I could just do a comparison of default settings, plus with this shader chosen? Or were there extra tweaks you wanted in there?

I deleted the original recommendations because I’m assuming that the vast majority of people are using 1080p displays, and shaders are really only good if you are on a 720 display (with the Pi).

I think for all shaders the best results are had when you use integer scale. This will ensure pixel-perfect scaling and, most importantly, that the scanlines are evenly spaced and the same shape.

There is also an option to adjust bloom strength and beam width/sensitivity, if you are interested in that.

I’m actually kind of jealous of those with a 720p display as they’re actually kind of hard to find, now. I was considering buying one for the retropie, but I think it would be cheaper to just buy a slightly more powerful computer like the mini Intels.

I’ll post steps to editing glsl shaders on the pi a little later- that would make a good video.
