Framerate drops slowly from 60 to sub 5 after an hour of play.

I have this exact same issue - it started in the past few weeks (no issues for a year since I switched to an Nvidia card). Exact same as you - my game runs fine, then it starts to stutter, and drop frames, eventually dropping to 1 FPS if I don't restart before that.

Tried absolutely everything to resolve it.

Windows 8.1
i7-4770k @4.3ghz
1x MSI GTX 770 (347.88)
8gb RAM, 1600mhz
Installed on SanDisk Extreme 128gb

Isn't an issue with the GPU - since other games run perfectly fine for infinite lengths of time. Tried running everything at Stock speeds too and the issue remains.

Yeah I definitely feel you, I have tried even more to resolve this to no avail:
- Reinstalled Nvidia Drivers
- Reinstalled the client on my WD 1TB 7200 RPM and also on my new Samsung 850 EVO 500GB
- Turning off the Steam overlay
- Running in Administrator Mode
- Turning all graphics down to the lowest settings (minus the LOD options that were mentioned to cause problems)

I did a bit more monitoring and I can confirm that my temperatures are completely normal. My 1st 980 sits at around 72-74 and me 2nd at around 61-63 throughout all of my gameplay. My CPU sits at around 60 as well and doesn't seem to budge.

If anyone has any other suggestions please let us know! I am really enjoying this game but this has easily been the hugest dampener in my experience. It will greatly hurt my potential for raiding if I'm going to have to restart my client every hour.

I have been having FPS issues too. My system specs are a 4690K, 16GB RAM and a GTX660.

Starting the game and tabbing to other programs while its loading (windowed full-screen mode) drops FPS to around 10-25. After that, rebooting the game and not tabbing while it loads does NOT fix the issue. The issue persist also after returning windows from sleep mode.

It seems that only and ONLY after a full reboot for the system, starting the game and letting it be active while loading process finishes, I get a steady 60 FPS in almost all areas.
