What exactly is this? Sorry to ask the noob questions but I have a dell 1400p and was wondering if I could use it or if I should use it and what would the benefits be?
It's essentially no different than SSAA, but instead of using your native res as a starting point and having the AA algorithm blow it up and send you back the interpolated results, you pick the res you want and it is scaled back down to native.
Ever noticed how a HD video looks much better when scaled down in a small window? Same thing!
