Hmm yeah you got issues there mate. Just upgraded my drivers to 314.22 (as I'd forgotten to) and disabled Vsync. Here's what I got, max possible settings.
Good old AMD drivers strike again. Did notice that disabling Vsync made the hair go screwy mind but then it's common on SLI given that Tress is a AMD tech.
still hot though, cards are as far apart as possible, and have 2 fans blowing air directly over them, and the case was open when the benchmark was run!
I was quite impressed with Tomb Raider. At the quality of the game and how well it ran. There were a few fps drops when the hair effects were close to the camera, but apart from that, pretty good.
Definitely one to play again at hardest level, searching better to skill up sooner. Apologies if this is a spoiler for anyone.
I'm guessing any higher and your rig will turn into a vacuum. Atleast that was my experience with reference coolers thus far along the entire 7000 series.
