Game files missing or corrupt

@Torossi21 

It is possible you are missing some Windows System files, run Windows update and download/install any available updates. 

Reboot and run Windows Update again, repeating until no more updates are available.

Thanks.

There wasn't an update needed, but I did end up running cmd - sfc /SCANNOW. This at least got me past the missing files error.  However, the game is now crashing with the below error.

If you have advice for this that would be awesome, if not I'll search more and make a new topic if needed.

Thanks!

I'm getting the same crashes with the same code

Still going to have to play more to confirm long term, but I may have got it working. In addition to what was mentioned above (cmd for system files and verifying game files), I also ran Steam as an administrator, cleared out my download cache (steam > settings > downloads) and used the repair library function (steam > settings > storage > select drive and three dots to repair).

Unfortunately, this is still happening with the above error that we are both getting.

Going to use this thread to track things I've done. Currently dropped VRAM clock on my GPU by 60mhz, been running for 3 time trials in a row (knock on wood).

Dude, you were right to try reducing Vram clocks. The Access violation error that you are getting is usually invoked by either System Ram clock too high, or more rarely by Vram clock too high. In my experience though, too high Vram clock usually results in the game just closing to desktop with no error logged or a 'Device Removed' error & crash. System ram clock too high will allways give the 'Access Violation' error with a BSOD.

Try lowering system ram clock by 100mhz at a time & testing. If using XMP profiles (automatic Ram OC), Switch back to default ram timings (Auto) & test.

Good luck whatever the case.

FYI 1 : I've had this error only once in my entire play time so far. I believe that the issue arose due to me manually updating the nvngx.dll (DLSS) from 3.1.x.x to the latest 3.5.10. After a file verify corrected the .dll library, I have had no issues.

FYI 2 : Regarding any stutter you may have, I lowered shadows to medium. Everything else on Epic (disabled motion blur in game option), & that's it. No more stutter & locked to 60fps (emphasis on 'locked') as my 55" Sony is 4k 60hz.

System is : I9 9900k @ 5.0ghz (360 Rad LC), EVGA FTW3 2080ti Hybrid LC @ 2055mhz GPU, 8200mhz Vram, 32gb ddr4 3100mhz @XMP trident RGB, Corsair 1000watt modular PSU. Sony 55" 4k 60hz HDR for display.

*** Point to note ***

My GPU Vram clock is overclocked by offset +1200mhz. This takes it from stock 7000mhz to 8200mhz. I have yet to have a game crash (WRC) with 'my' Vram this high, pointing at very good stability with regard to Vram speed / timings sensitivity. Hence why I have advised you to review your system Ram settings.

Does it work for you now?

I have lowered the Memory by 100Mhz as well and it was stable until now.

The same error "Game files missing or corrupt".

- SFC /scannow passes without any errors, patched Windows 11 to the current release (already did that a couple of days ago)

- verify game files integrity -> no errors

The funny thing is, it happens after the stage, only seconds before the game tries to save the game (or maybe tries to access the cloud savegame),

never whilst driving.

ok, it happened while driving too...

Still hit or miss for me, but way better now.  Dropped car reflections and shaders to ultra low to help with stability and lack of stutter. Good call on the system ram too. I found the HP omen hub was overclocking my ram by default so that's back to default.
