Thanks for the great review. I've been waiting for Tom's to do a BF3 performance article, and this pretty much sums up my expectations. Good job.
Rocking out with an i7-950 and GTX480 at 1920x1200 and near maxed out settings. It's definitely playable, but it also isn't silky smooth. Benchmarking with fraps I recorded min frame rates as low as 31 across several runs. I think I'm fine as long as the minimum doesn't dip below 30, and overall I'm pleased with the performance results. Prior to the beta, after watching all the ridiculous in-game footage released online, I definitely wasn't expecting to be able to max out this game.
The game play and graphics are phenomenal, it's by far the most intense multi-player fps experience I've ever had. But then again, the last first person shooter I played extensively was BF2.
