I've been told that Resolution in game has no effect on FPS, but then I looked at Doom 3 results and I saw they went down as resolution went up so I got curious.
I dug up this graph on barfeats:
Along with this one:
And you can see the patter - resolution goes up - FPS goes down.
SO, I'm a wondering and questioning a higher authority on this subject. I just tried it in RvS but got no substancial evidence, it wasn't a very professional test - FPS actually went down it seemed.
UPDATE - - -
Does the fact that I have an LCD have anything to do with it?
Does resolution effect FPS on CRT's and not LCD's?
