Nope wont run 100fps constant, in smoke its awful. Many years ago my XP2600 and MX440 run it constant 100fps no problems, now my 9700pro and 805 3.2ghz struggles, im sure steam have added patches that rob performance, pc is running well atm just bought a new hard drive and I always close down unwanted programs and run gamebooster before playing.
Above post I meant M0 and recent R0 revisions, not E0 lol
