Hello! Finally, a way has been found to slow down the game and increase the performance (~ twice) for owners of windows 7. So, if anyone does not know:
1. Download the program Speed Gear 6.0
2. Run red faction
3. Minimize the game, open SpeedGear, press target and select our process with the game.
4. Set the speed, in our case it is 1 / 1.510 (Perhaps there are more optimal values, but it seems that this is the same, there is nothing to compare with)
5. Press apply
6. Back to the game.
As a result, we get a normal speed of the gameplay, and an increased fps (I had ~ 30, with explosions and destructions ~ 15, it became 56-70, with explosions and destructions 30-42).
Red Faction: Guerrilla: Tip (Slow down the game speed and increase the speed)
Not a very bad result. Dare!
