I´m Sorry to hear this as i just started playing it and the game crashes, i´m also sorry for that nuthead who said those things well like you said he can try him self too bad a persons spoils so much for so many greatful players keep up the good work
Sorry bro, I just saw this. You played 3 months after I played and it's now 6 months after I played. I have already uninstalled the game and Saves for it.
The one thing I recall that helped a lot (besides disabling A/V) was re-pressing the option key/s I needed as I went along. Like for ammo and grenades. You may not see this reply now either but for anybody else, I would defo at least try the trainer. Enough options worked for me that the game was a blast.
I would be sure to only buy the game on sale at this point just in case they've patched it yet again and it's not working now.
