It must be your hardware or software problem what's your specs, do you have loads of lighting and sound / oc software installed, are you overclocked, installed Anything new recently?
The only change was WC'ing and a i9 9900k upgrade from a i7 8700k, using the term 'upgrade' loosely lol. My GPU is a EVGA 2080 ti XC Ultra, both GPU and CPU under water. The GPU is +150 on the core, +1000 on the memory with 130% power target. Using OCCT on the most intense test. After 1 hour, no errors found. CPU is at 4.8Ghz on all cores with a healthy vcore of 1.23v, respectively this has been through Cinebench, P95, Aida64 Extreme (paid version) and OCCT. All run for an hour (except Cinebench) and no errors/crashing.
CPU sits at 60C under extensive load, GPU at 45C under extensive load.
I'm going to test removing the GPU overclock as I read once or twice on Reddit that even with a stable GPU overclock, it can cause the crash.
Also, with all of the above, I can play any other game for hours on end without a hiccup.
