Massive FPS Drop w/ Corresponding Drop in CPU Utilization

Support Technical Support

Been having this issue on and off for a month or two now, not sure what is going on. It happens infrequently enough that I just consider it a nuisance but I figured I would see if anyone here has any idea what is going on. Basically, I am seeing huge FPS drops from time to time w/ corresponding CPU utilization drops as seen in task manager. The issues seem to happen pretty frequently in Ardenweald, less so anywhere else in the game, though I spend a lot of time in Ardenweald so that may be confirmation bias. FPS is usually 60-100 (100 being my set FPS cap) w/ CPU utilization for wow.exe sitting ~ 23%. When this FPS happens as you will see in the image below the FPS will drop to 4-6 while CPU utilization on wow.exe will drop to 1-4%.

First, DX Diag:

Second, a screenshot of it happening:

Things I have tried that do not resolve the issue:

Reinstalling the game.
Updating addons.
Changing GPU driver versions.
Updating chipset drivers.
Changing graphical settings (DX11/12, currently one DX11 due to the Ardenweald flicker bug… another issue…), RTX on/off, etc.
Running the game on as close to a clean install as I can get by manually shutting down all other running programs.
Running w/ and w/o overclocks on hardware.
Thermal throttling does not seem to be an issue, the 3900XT is on a 360mm AIO, rarely crests 65c, GPU is even more frosty.

Things that fix the issue (temporarily) alt-tabbing out of the game, or literally just panning the camera.

It’s not a huge dealbreaker for me, like I said, it is fixed easily enough when it happens, but it certainly is odd. It almost seems like the exe’s thread priority just disappears and the PC stops allocating it CPU resources until I interact w/ the game at which point it wakes up.

I don’t see any performance oddities in any other titles I play, and no other sort of system instability, just seems to be an issue w/ WoW, other games play flawlessly.

Anyways, thoughts? Anyone else seeing a similar drop in performance at random times?

Edit: Another thing I just noticed while reproducing this issue. My wallpaper is animated and when the FPS drop happens in WoW it also affects the refresh rate of the animated wallpaper, so it seems like the issue, while being caused by WoW (or only happening while WoW is open) affects CPU performance of all applications currently open, or at least those that use animations/rendering.

I recommend checking over the errors section at the end of the report. Since there are blue screen codes popping up, it’s unlikely you’ll see official support on this, but I wanted to steer you in the right direction.

I’m not sure if the blue screen code is related to memory or IRQs, as they both have similar error codes. You can look them up here: https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/bug-check-0xd1--driver-irql-not-less-or-equal

Additionally, there are a lot of errors from the nVidia broadcasting executable, which I don’t know much about, but a quick internet search suggests that it grabs data in the background.

Thanks for the quick response Elocin. I got as far as finding the dump file, downloading a windbg tool to read it and finding out that the failure was caused by entryprotect, which I guess is a module that is part of Citrix which I have to use for WFH. I know windows updated the other day, I think the night before the BSOD referenced in the DXDiag, I must have completely missed the BSOD since I turn my PC on in the mornings and walk to the kitchen to make coffee. I don’t know if this has anything to do w/ the WoW instability, it could, but I also feel like it could be a red herring. As to Nvidia Broadcast, I’ll try uninstalling it for a couple days and see if that resolves the issue, thanks for pointing me in a direction!

I think someone else also posted about a sudden issue with their WFH software since the Windows update. Might be time for a rollback if the other stuff doesn’t work?
