It probably runs into a CPU bottleneck, also, not sure how well WoW works with mGPU. Just check your GPU load, if it ain't at 100% and you don't have a FPS limit, it's a CPU bottleneck.
I found wow somtimes get stuck in background which cause low FPS if you have background fps lock on so check that. Then last thing are you playing full screen? If not try that, sometimes my card gets stuck in 2d clock speeds using window mode.
I skimmed through that thread, it seems some Nvidia users also have the same problem, while some AMD users also don't.
There is also talk of a Microsoft update causing problems, this much is true,
Its KB3004394, find it and uninstall it.

Same fps just tried it![]()
Tried searching for it and can't find it, so did they patch it?
I also just looked at my GPU activity and it went from 0-100 then went back down to 1-9 and went back up in chunks. is that normal?
It might be worth trying your 2500K at stock speed to see if that helps.
My thinking is that budget Z77 motherboards are generally aimed at Ivy Bridge which is a much more power efficient processor than the older Sandy Bridge architecture, it's possible that your motherboard VRM's are throttling under the 4.4ghz overclock especially if you're raised the voltage quite a lot higher to reach it?

Did you say that this was only caused by newer drivers? if falling back to older drivers helps then I can only assume it's a driver issue.
It came after the omega driver update, but since then i've reverted back to previous drivers with minimal changes
I would crossfire the 290. Upgrading to a GTX 970 is just not worth it. I went from a Radeon 7950 to a 970 and the difference in the latest games is not amazing or double as some would have you believe. Older games are faster but new games struggle.
Farcry 4 barely runs between 50-60fps maxed out and even Dragon Age has to be run without AA to runs between 50-60 fps. A 7950 ran these at only about 10-15 fps less. This is on an i7 3770 running at 4.3GHz. The higher bandwidth of the Radeons definitely makes a difference when game details are maxed out. Adding another cheap 290 would be the best bang for the buck at 1080p.
And Dubz if you want a change like people where saying get a 970 its a very good card ive had amd last few and won't be again for various reasons which this post isn't the place for. plus like you said you have another machine for the 290.
Also,I have played D3 quite a bit and even with IB and Haswell Core i7 CPUs you can get framerate drops and I suspect it is no different with WoW too. Its probably another limitation,maybe on the server side?
They might have messed up the registry or something, do you have a spare hard drive you can bang a fresh copy of Windows on? just avoid the Omega drivers for now.
An dubs all the rest of your bits are fine
