@Alex p. - You don't happen to have Logitech wheel do you? At one point in your Hennessy Exorcist video (just before the 2min mark) it looks like your brake is slightly on, which in my experience is a sign of a dirty/failing potentionmeter in the pedals on the Logitech G series wheels. Can be fixed by either disassembling the pedal, removing the pot and opening it up and cleaning it, or by replacing/upgrading the pot itself.
