The stuttering with the music is still present for me whenever I hit another car or an object, or if I hit the brakes hard enough when driving. Plus, I'm still having to spam alt + enter when loading into a race because of it getting stuck.
I can't wait to see Motorsport 5 and 6 possibly get this same treatment in the future, because I've been playing FM5 on Mezcal. And while it runs pretty good, there are some slight graphical glitches with it.
