I have been getting extreme amounts of texture and shadow flickering, which includes the whole screen blacking out at times for quite a while now. It started not long after the Steam release, I booted it back up after a couple of months of not playing it and the problem is still there. It appears to get worse the longer I play which I know makes it sound like a hardware problem but I had the same issue a few months ago with my old AMD card and it is still doing it with an Nvidia. I'm sure I seen this mentioned in a thread a few months back but had a look and couldn't find it. Thank you in advance for any help.
