Really bizarre issue. When I use Fullscreen or Exclusive Fullscreen, my game turns into a stuttery mess.

My first thought was that this is because the pixel count is higher. The thing is, when I manually set the project setting to 2560x1440 Windowed, it runs perfectly fine. Only when I change the setting to Fullscreen or Exclusive Fullscreen does it start stuttering out of control.

No idea what's going on here, I've been playing around in the visual profiler driving myself crazy before I realized this was the only consistent thing causing issues.

ANY ideas are appreciated at this point, thanks in advance!

i've never had this issue with two monitors, but my monitors are not 2560x1440

#

it's possible this is an issue with the engine?
