How to fix persistent FPS drops in World of Warcraft after the latest NVIDIA update
The most likely cause of your FPS drops is that Max Foreground FPS was set to 0 after the NVIDIA update. To fix persistent FPS drops in Dragonflight, navigate to your Options by pressing the Escape key. Then, go to Graphics and ensure that you don’t have Max Foreground FPS Toggle enabled. If this is enabled, disable this by ticking the box.
Another possible solution to your problem might be hiding in the Multi-Sample Alpha Test. Again, go to Options by pressing the Escape button and under Graphics and Anti-Aliasing, you’ll find Multi-Sample Alpha Test. Disable it by clicking on the box.
I figured out that my issue was that last step > Graphics and Anti-Aliasing >Multi-Sample Alpha Test. Since I turned this off before I logged into game for raid last night, I only experienced a bit of the typical lag we see, not the horrible slide show, not to mention I did not experience that freeze like I have been.
