I think for those having trouble with black screens, freezing seemingly on certain tracks is probably just finding a correlation but it is surely not about the track itself; There shouldn't even be anything in a track capable of effing up your system.
For me and others I have spoken with at work, if you are on Nvidia GPU, the whole of the 4XX.XX series of drivers have been awfully unstable. I don't know if there is any particular wizardry that CSP is pulling that might cause them to **** the bed more than usual but I know that for me, lockups and driver crashes are something happening not only occasionally with AC but also in other 3D applications / games. I had it with AMS2 this morning.
I have 2 systems at home and admin some others- all NVidia GPU, some old, some new.
Of my home systems, the newest one has had a fresh windows install this week, migrating to enterprise. Still having driver issues now and again if I use any of the later 4XX.XX. Reinstalling GPU drivers loves to **** with my audio setups as they always decide I want HDMI audio enabled again and then Windows ***** the bed regarding my other devices because Windows is persistently ****ing awful.
Anyway in general, nothing too deadly for me if it does lock up--
I usually either use second monitor, or if unable, blindly navigate to the the very handy driver restart utility included in 'Custom Resolution Utility' here:
https://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU.
Pinning the restart64.exe to start menu is handy for easy access.
That is more thorough than windows own method but if it's really locked up and navigation is difficult, Win+Ctrl+Shift+B forces Windows to restart the graphics driver then using the restart64.exe utility after I have regained control fixes any lingering issues there might be.
I will stop rambling now as I am on my phone and should get back to my (very rare for me) drinking session, not sure what prompted me to bother writing this boring mess..
..Carry on chaps.
Edit: I never realised GTPlanet was so linguistically prudish. Can we not use the naughty adult words on here?
