This is gonna be a long post, so strap in.

Since before the 2.0 patch I've always had crashing issues. It most commonly occurs when I reload or just after, but occasionally seems to happens randomly.

Here's the most recent report, but all of them I've checked so far have been similar:

Things I've tried based on googling, in no particular order:
======
* Bios: Updated BIOS.
* Bios: Disabled hyperthreading.
* Bios: Switched RAM from XMP to Auto.
* Windows: Updated all drivers.
* Windows: Turned off DEP completely.
* Windows: Set min and max CPU power to 99%.
* Windows: Set Cyberpunk2077.exe and REDprelauncher.exe to run as admin and switched them to Windows 8 compatability.
* Windows: Wiped DX12 cache
* Windows: Removed all read-only flags from all files in /GOG Galaxy/Games/Cyberpunk 2077
* Windows: Did "sfc /scannow" again. (no integrity violations)
* Windows: Ran 60 min OCCT extreme memory stability test, 0 errors.
* Windows: Did a 4 hour TestMem5 run using anta777 settings, 0 errors.
* Deleted directories prior to launching:
...\AppData\Local\CD Projekt Red
...\AppData\Local\GOG.com
...\AppData\Local\REDEngine
* Windows: Disabled and deleted all Nahmic products
* Windows: Added Galaxy and Cyberpunk as explicit firewall and antivirus exceptions.
* Windows: Renamed CChromaEditorLibrary64.dll
* Cyberpunk: Turned off cross-platform saves.
* Cyberpunk: Deleted then reinstalled, including registry files, everything except save games, which are all post Patch 2.0

Frankly I'm at my wits end, and utterly frustrated.
