Not sure what the teams use these days, as they seem to have become more secretive about it as the technology has gotten better. But I’ve seen some of the commercial products that have the enormous surround screen, moving chassis, and thing attached to the helmet to simulate force on the neck. I’d imagine the better off teams have facilities like that. The software would certainly be better than the CodeMaster game, but I can’t imagine it being that much better than iRacing (apart from being more customised to the current tracks/cars).
