WoW Classic FPS stable, game is not

Hello there.

I would like to ask for help because I am quite helpless regarding the issue that I am facing in WoW Classic.

I have 60 fps all the time, doesnt drop below that. Game is buttery smooth. But then, out of nowhere, at any randomly given time, game begins to be really choppy and FPS feels as if it was 15-20 instead of 60. Funny thing is, that even when this is happening, FPS is still 60.0 and does not drop!

The only fix to this issue is alt-tabbing back to game, or pressing the windows key and manually clicking into the WoW window. Game is buttery smooth again. But understand, this fps frustrating problem can happen 10-15 times per hour, sometimes even more often. Alt tabbing that much is just pure frustration. This problem does not happen in any other game.

What I tried to do to fix this:

  • I tried to change to dx12 in wow classic options
  • I tried to disable foreground and background FPS limiters and I also tried enabling them with 60 fps cap
  • I tried right clicking on Wow.exe and disabled the fullscreen optimization thing
  • I tried deleting the WTF and Cache folders in WoW
  • I tried disabling all the addons
  • I tried putting real-time importance to WoW in task manager
  • I tried lowering the resolution

Nothing helped.

I remember I didnt have this issue before. When classic launched, I played on laptop and on laptop screen, this wasnt happening. Then I bought an external AOC 24" 75hz 1ms monitor, connected it to laptop via HDMI cable, game was still going great.

Then I didnt play for maybe like three weeks and needed the HDMI slot for PS4 (as the monitor has only 1x HDMI, DisplayPort and D-SUB port) and still wanted to connect my monitor to laptop as well. So I bought an D-SUB->HDMI adapter and connected the D-SUB cable to monitor, which I connected afterwards into the adapter, and out of the adapter, HDMI cable connects to the laptop.

I started having this issue around the time I connected the laptop with monitor like this. But then again, it does not have to be related to it at all, because no other game does this to me.

I am playing wow on Fullscreen windowed.

I am attaching the DxDiag thingy and desperately ask for help. Thank you very much in advance.

I don’t know if we have the exact same problem but since Phase 2 I have occasional lag spikes that last 1-5 seconds, it’s really frustrating. No FPS drop.

Thankfully I managed to fix this issue, I will post the solution here, it might help somebody in the future:

I reinstalled NVIDIA drivers to the latest ones + I went to NVIDIA Control Panel and forced VSync ON and Tripple Buffering ON for WoW. It is absolutely smooth now and the issue is gone.

Before I had Vsync and Tripple Buffering set on OFF in NVIDIA Control Panel.
