I play WoW and like to run my settings high. I found that pretty much all the fog effects kill my frame rate. Eventually I spent about $200 on a EVGA GeForce 260 GTX 216. I cranked every setting in WoW to the max. I flew out of Dalaran over Crystalsong Forest and almost threw up. I could see everything. Normally the distance fog limits what I can see from high up but this time I could see the entire zone. I got a very strong feeling of vertigo from the realness of the altitude that I haven’t previously experienced in a video game.
