I have some mystical problems with fps since yesterday. I started playing 3 days ago, my fps was between 140 and 500, all was ok. But yesterday when i logged in, it decreased to constant 62.1 with some notable freezings (same problem with my second PC. Second PC is very old, but here WoW runs with 122.1 fps now). Latency is about 40 ms.
Why this problem is mystycal?

My home PC: Inter Core i7 4790, GTX 770 , 8 GB RAM, WIndows 8.1 x64.
My second PC: Inter Core 2 Duo E6750, ATI Raden HD 3800, 2 GB RAM, WIndows 7 x32.
I reinstalled WoW at my home pc, but nothing changed. Today i will reinstall Windows. Also i need to say, that retail WoW runs with 80-160 fps (Ultra settings).
Hope you will help me .
P.S. Thank you for great realm
