Various players have been reporting a “Fatal error” being encountered when trying to play any of them. However, there’s two workarounds I know of to get around it. What’s interesting is that this might be specific to the Steam Deck OLED, as it’s to do with HDR not working. So you can try this launch option first:
DXVK_HDR=0 %command%
To do this. Go into the game in your Steam Library, over to the little cog icon on the right for the Properties, and put that in the Launch Options box.
Another potential workaround is to force DirectX 12 for it:
command% -dx12
Mildly off topic, but as a steam deck user, not another penny to rockstar from me. They can suck a bag of dicks.
That’s how I’ve been treating any other dev that mistreats the Deck, Rockstar won’t be different. That’s how it should be.
