Guild Wars 2

the game work now, but it looks like ive got rollback -lost near 30min or so of game progress -nothing special tho…

I have sound in game but it feels pretty noisy (like 96Khz mp3 -something similar).
Iam using USB audio card -Schiit Bifrost (well not exactly audio card its DAC)
Also sometimes got just noise instead of sound till game reload.
