I'm running a 9800pro, i've turned on Direct3d in the Fandango options, and i've got my ATI settings on custom with anti-aliasing on, but its still as jaggy as ever. Any help?
AFAIK, anti-aliasing does not work with Grim while using an ATI card. I never did manage to get it working, so I've simply assumed that it isn't possible.
If the backgrounds are 640x480 prerenders, they'll probably look worse when scaled up to a higher res. Only the real-time polygonal elements (like the characters) would see any real benefit.
upon investigation, it seems like 'Residual' (the name of the emulator) is still very early due to the fact that its a pet project of a pet project, so I doubt you'll be seeing it very soon
