Checking meow, will edit my post with results.
EDIT: WOOOOOOOOOO!!! This seems to have fixed it with flying colors for me. Played BF4, 64 man conquest, Siege of Shanghai. Was able to play the ENTIRE MATCH (800 tickets) without crashing or performance hits. Was mostly in the 120FPS+, had a drop to 77 when tower fell but then went back up to hover in the 130-140 FPS range. Definitely was waiting for this update, even if it's only BETA :)
