Hello, I was going to start a new thread, but seeing that I have the same issue I'll post here.
So what happens to me is I can play through campaign for about 15 minutes. Then it locks up, can't access console, or menus, and it freezes, kinda like when the game pauses for a few seconds to load, however it doesn't come out of this freeze.
Usually I restart, and go through the area, it pauses for a few seconds to load, and I continue on. However I've hit a problem. Just after the offices (the load save file says i'm 10 minutes in) you go up a set of stairs, and there is a security guard killing head crabs. You ask him to go with you, and you go up another stairwell. This stair well has an auto turret at the top that usually kills the guard (unless you tell him to wait). After you get off the stair well you turn left and go down the hallway. Then you take another left, and there are two vortiguant. You kill em and continue on. Right where their corpse falls is right where the game freezes at. I think its another loading section but I can't be certain. I've reloaded and gone through the section a dozen times and still no luck.
I followed Dark Xeno's suggestions, making sure everything is closed in the background, defragmented hard drives etc.
I've had this trouble on my gateway desktop, and my asus G50vt-x5 laptop. Both of their specs are posted in my profile.
I tried to select rendering to be done by hardware in the video options menu for the game, and it would not allow it. When I clicked apply the game would freeze. I set it to run open GL which should work.. or should I try a different setting?
So its running software rendering at 1440x900 and that I think could be the problem. How can I get it to use hardware rendering?
