Just tried it, but doesn't look much better. They're are just some parts that have horrible "shaking" like the track preview, or when the race is starting or around the finsih line but then the middle of the course plays just fine (now that "Dual Core" mode is off). I don't know...at least I got the latest version now though! Thanks!
