I would highly doubt it's a HDD issue. I don't even really understand how it could be. It's almost definitely GPU/Settings/Driver related. Which one of those? Your guess is as good as mine, but I think recon might be on the right track, and I still say that it's really not that bad (in the clip you showed, anyway). I guess small little things like that just don't bother as much as it does for some.
yeah i guess so...I'm just going to have to wait for 12.5 i guess I think my 12.4 drivers might of screwed some things up
