I am useing a matrox 3htgo digital, nvidia 9800 gtx+, amd phenom x4 9500, 2.2 ghz. Monitors, hp w2207h in center, acer x223w left and right. All 3 are 22" 1680 x 1050 native res., .05m/sec. frequence responce time [you can use a different f.r.t.] but all three must have the same one, and opperate at 60hz. also useing ir4 headtracker. I am very pleased with the matrox in gaming. Frame rate 30-50 in mission editor,all settings low except tex. med.In oil war 1, f.r. can drop to 3, or 4 at times, but averages 12 to 14 in battle, 18 , 24, average flying to the job. In oil war 2 about half way through f.r. dropes too low to play. oil war 3 bad at start ,no good to play.
