Same issue here, or very similar issue at least. Game freezing after a couple of minutes of gametime, was improved to 15-20 minutes bydefragmenting and reinstalling the game, but still crashing no matter what.

Same problem here, I'm using wifi and an old gaming laptop (Cored2duo 2.6 ghz, 260M GTX, 4g ram, latest nvidia drivers, no antivirus) game was running fine in the first months of alpha, now It becomes unresponsive after 10-30 min, and I'm forced to kill the process. It's worse on the experimental than stable, but happens on both. Noticed my fps is pretty good (30-40 fps), the freezes just happen out of the blue. I've defragmented my HDD, cleaned up my comp, making sure I'm not overheating, not sure what to do to fix this issue.

I confirm this.

this screenshot looks like something from a movie where night scenes are actually lit by powerful spotlights that make everything shiny and colourful. I don't think it's a good idea to go this route. True dynamic lights for flashlights however would make it a lot better, but given the scale and nature of the game I'm not even sure it's possible.

+1 for gray's post, make the weapon's barrel drag behind your crosshair position depending on the attachment equiped, mouse sensitivity should be 1:1 for obvious comfort reasons.
