I had some black screen crashes that forced reboots for me too,ended up being the game demands a pagefile.If you use any textures now that are High or Extra,even if everything else is off it would result in a crash but enabling a pagefile it was pretty much flawless.
Its a bit different then it was in December,i haven't had a need for a pagefile and haven't ran one for a few years but for whatever reason this game likes one so i set up 4gb for that.
Vram usage is very odd too,those High+Extra textures suck every bit of memory out of my 970,it was eating into the pagefile lol and i have 8gb of system memory.Normal textures i could run without a pagefile without a issue.I was hitting 9100mb total memory usage,not including a maxed out 970 with High alone....
Wonder if a patch brought on a memory leak?Appears to be 2 new ones since December.
