on benchmark I scored like 11k and on last beta had 0 problems, but since last maintenance, I have the same problems. i7-3770 asus gtx670 ssd ecc ecc. If u are using the logitech gaming software and it's updated to the last version it may be it.
For me the 8.5 is messing really bad with FFXIV, but the 8.46 seems better but if i remove it it's worse lol. I have keyboard headset and mouse from logitech so kinda have to use it :/ :<
