This is a nice plugin....BUT, it has two major issues:
1. when in lower resolutions it just looks like a fullscreen blur, when anti-aliasing doesn't do that. FSAA should only blur edges, even in low resolutions.
2. when changing resolutions it leaves a "screen capture" per-se of the last frame viewed, so if you don't have a skymap running it shows a picture of what you saw last.
Other than that it's a nice plugin, only those two things mean I can't use it
. You should've also mentioned that you need to reset the FSAA to 0 before changing resolutions, if you don't it crashes the video.
If you could fix those two problems I mentioned it would be complete, but nonetheless, good job
edit: the 1x, 2x, 3x, and 4x actually look like 2x, 4x, 6x, and 8x respectively. They look nice.
