Issues since last patch playing on USB

[Fifield]

Ever since last patch playing EQ off a USB has been god awful fps. Like about 4fps.

I tried clicking off the adv lighting like someone suggested in a thread not related to USB. it seemed to help a bit but its still awful

I know the read/write speed on usb's are not the best, before the patch i wasnt getting crazy frames but at least it was playable.

Any suggestions? Logs are off.
