Re: PC game shows PlayStation buttons.
As far as I know, the game doesn't allow user to choose whatever button prompts to use and automatic switch to whatever button prompts it think it best suited for the racing wheels/wheel rims/wheel hubs.
The Fanatec CSL Steering Wheel P1 V2 is categorized as a PC and PlayStation-ready wheel (require a supported wheel base in case of PS consoles) on Fanatec website. Is the mapping in the game looks like the one in this image from the PDF from Fanatec site?
