FPS issue after maintenance

[Cauli]

Hello,

 

After today's maintenance my performance went down by a lot, I used to be able to play on max graphics settings with 40+ FPS almost everywhere (minus 24-man) but since today I barely reach 20 FPS in 6-man dungeons with the same settings and max 35 FPS on lowest settings (so low that I can't even see the DT lava countdown above my character's head). I know of one other person who has this issue in my clan, and some other clannies said their FPS actually increased. 

CPU: i7-5820k @ 3.5 GHz

GPU: NVidia GTX 970

Using 64 bit client

 

Is anyone else having this issue?

 

Kind regards, and thank you

@ProjectZedThank you! Great tip, everything appears to be back to normal. No idea why my PC suddenly decided to park my cores (it never did that before).
