Ok i'll explain the problem as quick as possible.
Ever since legion patch my game will randomly drop from 60 fps to 45 fps for a split second while in combat, a framespike. My first thought was, ok its my ui, deleted entire wtf/interface/cache to make sure it was. To my surprise this issue still occured. I tested it on beta (which is located on my HDD) and had no issues (at the time the live build and the beta build were identical.)
So I decided to copy my live WoW folder to my HDD and the problem is gone, I no longer had framespikes.
Obviously I want WoW on my ssd, its the main game I play so I decide to a clean install of WoW back to my SSD.
The issue is there, 3 pulls in to a dungeon and framespike.
At this point my mind is blown.
I ran a full diagnostic scan using ssd intel toolbox and it completed just fine, smartdetails is giving me no errors either.
It is a fresh windows 10 install, (2.5weeks old), Overwatch works fine on the SSD, not really got any other games on it I play currently.
Things I haven't tried yet: Reinstalling GPU drivers (seems pointless as if it was them surely the issue would occur while the game was located on my HDD?)
System: windows 10 64 bit (located on the ssd.)
4770k
asus z87 pro motherboard
270x R9 Msi gaming 2g
Intel 530 SSD, and a WD 1tb Caviar black.
So if anyone has any ideas to help pinpoint or resolve this issue, that be a huge help.
ps: WoW is located in my gaming folder, which is in the root of the SSD, not sure if that is at all relevent.
