SimSpeed - what exactly is it and what are the implications
I have a mid range spec PC (maybe its classed as lower than that these days), AMD x2 6000, 4GB 6400 DRR2, nVidia 8800 GTS, Vista x64. Not particularly impressive by any means. When i play the game on low settings i have around 100 frames per second. When i put the settings to high i have around 50 frames per second. Obviously my PC is running the game at an adequate speed. The most i've ever seen my sim speed is 7 and it quickly drops to around 2 late game, i've had it as low as 0 on a 4v4. Regardless of the sim speed my frames per second stay high.
So what exactly is it, how is it calculated? Why does changing the graphics settings appear to have no effect on it?
Also, what difference does it make to me and other players what my sim speed is?
