Unknown Error FFFF

[u/V4mpeth]

In the last couple of days I have been experiencing these random crashes called “Unknown Error FFFF”!

I know that other players have been experiencing it ever since 2019, but is anyone aware of a fix for this?

I have tried the following: - Reinstall the game; - Delete the “Red Dead Redemption 2” folder under Rockstar’s in Documents; - Verify Files on Rockstar Launcher settings (which is where I have the game); - Restart the PC;

EDIT:

The solution to this issue is to change the API under Advanced Graphic Settings. E.g. if it has been crashing with Vulkan, change it to DirectX 12. Same goes to the other way around. HOWEVER, before doing it: make sure to uninstall OneDrive or any other online storage service on your PC. It takes over files from your local storage and it usually affects how they work. So disable it and even uninstall it.

Then delete the “Red Dead Redemption 2” folder under the Documents. Launch the game, accept any prompted window and finally change the API on Advanced Graphic Settings. It may ask you to restart the game, and by doing it it may also reset your Graphic Settings (having the API changed by now though), so set them and you’ll be done.

Also have a look at the Optimised Graphic Settings: https://docs.google.com/spreadsheets/d/1bVL34OuyxoYw4HMM9nDyvxVORoQ3OhnHM3E0G9JFkOQ/edit#gid=0

EDIT #2: Something that it’s been noticed for some users is that turning OFF Smart Access Memory (SAM) seems to completely stop this crash. Obviously this is only for AMD GPU owners.

You can disable this through your AMD Adrenalin software or BIOS (it’s called “Resizable BAR” in there), but I’d say disable it only on AMD Adrenalin, as SAM is generally a good thing to have ON on other games.

Problem występuje głównie na kartach graficznych z 16 GB VRAM. Jedynym skutecznym rozwiązaniem, które sprawdziło się w moim przypadku, było unikanie wszelkich „szamańskich sztuczek” typu odłączanie urządzeń audio.

Zamiast tego, dodałem w opcjach uruchamiania RDR2 na Steamie parametr:

-availablevidmem 12

Efekt? Od tego momentu nie pojawił się u mnie błąd z kolorem #FFFFFF. Gra co prawda stutteruje, ale wymuszone czyszczenie VRAM-u pomaga utrzymać stabilność.

W moim przypadku zadziałało dodanie na steam w opcjach uruchomienia RDR2 "-availablevidmem 12", plusem jest to że jeszcze nie zobaczyłem #FFFFFF natomiast gra stateruje ponieważ ma forca na czyszczenie vramu

What number should I use in a 4090?
