memory leak? (yes i know since HoT blabal)

So i played gw2 fine for ever, but now i reinstalled everything on PC and sometimes i dont know what its but gw2 runs like im using some win95 PC, after i shut down gw2 and try restart it, it will always tell me to repair.my question is repair what? i never got a error its just that it randomly runs amazingly bad and other times it runs smooth as fuck even if i let it repair and start game up again its fine i didnt restart PC i didnt do anything beside a repair.

but it can also happen if i play gw2 > runs smooth as hell > logout > play again later (pc didnt restart whatsoever) gw2 runs crap after 5 mins and needs repair again.

i mean is there some easy solution to this? i checked my ram using from gw2 when this stuff happend it was actually on 2gb under heavy load which to me sounds fine but ingame looks like my pc cant handle it.

not sure what i got (but ran fine for years already) but i believe its i7 3770k 16gb ram 970gtx disk are all SSD
gw2 running off the 64bit also.

i just dont really understand why its doing this which is what i want to understand! :angry:

I once had the same issue, running memtest turned out the memory was faulty and if was affecting GW2 in this way. Maybe related issue?
