It's a 2004 game, so I would expect at least 30-40FPS minimum.
Intel Pentum D 2.8GHz
1GB DDR2 RAM
Nvidia 7300LE 256MB
I know the rig sucks, but the strange thing is, when I'm playing the Training section of the game, I average nearly 60FPS. It often touches 75. But in the missions, for some reason, I get an average of 27-28. I use EVGA Precision.
What can be the reason? The training section has is full share of shooting and action. Even in intense scenes, FPS don't go below 50. On the other hand, in missions, even when I'm standing still, I get ~28.
Vsync is off.
Perhaps the Training session only loads textures up to a limited distance and/or has far less complex textures? I dunno, but it's possible the training session doesn't utilize the full effect(s) of the 3D-engine that the actual game does.
For troubleshooting a particular game, I always find it best to check the game's support site.
