korell: Am I right in thinking that this is the first game you are playing?
JMayer70: Don't really see the relevance of this, but no it isn't the first GOG game I've bought
You misunderstood. I didn't mean the first game you've bought from GOG, I meant the first game in the Red Faction series. GOG has both Red Faction 1 and Red Faction 2, so I was just trying to confirm which one you were playing. Now I know you are using Pure Faction I know it is the first game.
Anyway, provided you are using Pure Faction 3.0c (the latest version as far as I know), then the only bug fix I'm aware of is limiting the framerate as high framerate can cause the submarine to explode on contact with water, which I can only imagine is suggesting that a high framerate increases collision force. No idea if this would fix the drilling vehicle crashes but you can give it a try, anyway. To limit the framerate, use the console to enter the command r_maxfps. Set it to about 50. Also, you can turn off fast animations, too, as they seem to be a simplified set of animations that helped the game play better back at the time, but it isn't needed on more modern machines.
Other than this, I'm not aware of any other Pure Faction problems. I played through it fully last year, but that was before it came to GOG.
