If you have an AMD system then take a look at this post from the other DX 12 error thread, there's a post by reitilein in there around page 15 that worked for me twice, I only had to do it twice because i ended up resetting my pc, but both times ive followed his steps it has worked, Its just a bit tedious to do (15-20 mins start to finish) if you follow this start to finish you should be able to play with no problem (Ryzen 9 5950X, Radeon 6700 XT here)
The Post:
Solution that worked for me.
AMD Ryzen 9 5900x
AMD Raedon 6700XT
Win 10 until now
First I flashed my bios to the newest version. Took me about 20 Minutes if M-Flash (usb stick).
Now I deleted the 2x dx12 files (shadercache in steam games directory and c:user:nfs-unbound directory)
After That I downloaded the AMD cleanup utility tool and the ccleaner (test version).
Also the AMD GPU Driver 22.11.2 (that was a mistake, even when NFSU is now supported, it lagged like hell in the game with this driver)
---> use 22.5.1 (1 before 22.11.2)
Now I started AMD cleanup utility tool
--> Tool restarts pc in WIn 10 Safety mode. After that all amd drivers will be removed.
--> after that I installed and used cc cleaner (i had no internet connection in safe mode, but i didn´t need it)
I cleared the whole registry with all amd files (i cleared everything, but my pc is still runing...)
Now i press windows+r key and typed "msconfig".
There I choosed "start" and deselected "safe mode". Then I confirmed this.
After that I restarted the pc in normal mode and installed amd 22.5.1 driver.
