I've been curious about simracing lately, mainly because simulators always fascinated me.
In online communities the consensus basically is: when going past rookie you *need* high-end controller hardware.
Rudy van Buren recently won the McLaren simracing competition, using a Logitech G290 . Before that he used a G27 . Both are entry-level hardware.
Remember that next time you think you need better gear to get any progress.
