It's not so much a problem as an annoyance; in a lot of games I see artifacts that I'd very much like to get rid of, but I'm not sure how.
Here's an example:
See the white pixels on the edges of the ship? That's supposed to be from reflected starlight. I'd like to make that smooth and blend properly instead of the pixelated mess it currently is.
Can someone point me toward the correct setting to modify? I'm already running with 8x AA which my rudimentary understanding of graphics says should have fixed that...
Note; I'm running an nVidia GTX260, and using the official drivers, and have no problem using the "force all apps to use this setting" option in the nVidia control panel.
