You would have to run it against every single map in rotation to account for the idiosyncrasies of each player's creations from half the fields in each country. There are maps I cannot sit in any tower within a sector of the HQ or a strat and not have my FPS stuck at 36-42. But, if I move to fields away from those areas, 59-60 all night long.
Your benchmark is really the FPS. Anything causing stress on the CPU\GPU while in the arena shows up in your FPS numbers. Unless you have a special monitor, LCD with vsync on, will be at 59-60 as your benchmark. But, that is no guarantee of being a game gauwd. You still need to factor in your Internet connection and that of each player you are shooting at.
Benchmarks in this game are meaningless to our ACM gauwds who some still play on a cheesy laptop with a mouse with WiFi and satellite modem. They have chosen to be so good at ACM that their poor personal Benchmark is no match for the fact you have just been setup to stall 100 feet in front of their guns.
