Its a brand new system built over Christmas.you dont have an older processor by any chance do you? i believe after the update your processor needs to support AVX2. my mate has an i7 3770 and it went to fine to buggy after the patch and that is the reason.
personally i accept things move on and new games not running on old hardware is regrettable but understandable.
however bringing in a patch which breaks old processors post release? that is out of order imo given a purchase decision was made on the hardware requirements and any refund windows will have passed.. Fortunately the backlash has been so great that i think that is gonna be patched out again however i suspect this does mean that soon older processors are gonna have games they are unable to play despite being capable from a purely performance point of view.
9800X3D, 32GB of C30 6000mhz ram, Gigabyte Eagle X870 motherboard and a 4070Ti.
I've managed to fix the problem, I had a CO of -30 and a PBO of +200. Once I had disabled PBO the system has been fine, I think maybe a -30 was fine until the game updated which started causing the crashes.
PBO is still disabled and played all weekend without a crash. I'll try with a -20 or -25 and see if that makes any difference.
