Massive FPS increase with Resolution decrese (?)

[Anvilfolk]

Well, if you go from a resolution of 1920x1080 to 1600x900, you get 70% of the pixels you had originally. If you go down to 1280x720, you get only 44% of the pixels you had originally. The graphics card has to render all the pixels... if it has less than half of them, at least creating the image and sending it to the screen should be around twice as fast.

Of course there's all the computation that you need to do either way, but I think post processing effects are applied to every single pixel. Anti-aliasing and pixel shaders are some examples. The less pixels you have, the faster it goes.

Correct me if I'm wrong though.

I don't get why so many people complain. I don't think I've ever played a game with AA on, or pixel shaders on max. Or over 1280x720 for that matter. It's not that bad. People are complaining about not being able to have AAx8 or whatever it is, heh.
