I don't think you've understood what i've been asking, or maybe i didn't understand your answer.
Let's take this example:
#define VideoMem "256"
#define CpuMHZ "3000" ---> 3.0Ghz SingleCore (let's say that the game works very fine on a 3.0 single Core)
#define PhysicalRam "2048"
And i have a quad Core at 2.8 Ghz. The ISS file is comparing only one of my core's (2.8< 3.0) or all my core's (4*2.8>>>3.0).
This is the thing i don't really get. I'd be thankfully if you could explain it the best you can.
Thanks.
