Since I'm playing at 1280x1024* res I want to add some anti-aliasing. But setting it with the Nvidia inspector doesn't seem to help. Does anybody have an idea how I actually apply AA? I've already googled for AA bits but haven't found one.

*I'm playing at this res because there is no proper widescreen. Widescreen resolutions just strecht the entire frame that doesn't look appealing.

Force the anti-aliasing in the NVIDIA control panel, and select override. The game indeed cannot run in true 16/9, just click on "nglide_config" in the folder, select your native resolution, and 4:3 for the aspect ratio. Worked for me like a charm.

I've already tried that but it doesn't apply. The game still gives me edges. But right now it doesn't really matter because I've finished it a couple of weeks ago :)

Thanks anyway!
