I saw someone suggest this in another thread to help with the problem of crashes and such, I've been finding it's been a help. Not perfect, but a huge improvement. nVidia Control Panel > 3D Settings > Threaded Optimization > change from Auto to ON
Take it back, I only experienced a couple lucky fluke sessions. Back to crashing within 1 to 2 minutes of initially spawning. Time for a rollback to the previous build that was in place before the patch. No sense in trying to fix something that's hopelessly broken.
