There's been some talk around here earlier about how rendering performance is impacted by resolution. When we use webgl shaders they seem to be rendered after everything has been scaled up instead of before, which means the higher your desktop resolution the greater the strain on the gpu. I see this on my own computer; when a game with several shaders renders at 2x scale everything is slick but bump it up to 3x and things start to get jittery. And yep, my drivers are relatively fresh.
Shader effects often don't need to get rendered at any more than the non-scaled game resolution, or maybe 2x game resolution. So, could we please have some kind of 1x and/or 2x rendering option that gets scaled up to fullscreen after all the gpu-intensive work is done? I remember Ashley mentioned this kind of thing as a possible solution and I really hope you guys will consider it. A possible extra benefit: If everything is drawn at 1x res first then scaled up we could get a realtime toggle for point and linear sampling maybe. Yes? Sounds good, right? :)))
