weird bug with streaming video that I narrowed down to Beamng

Hello, I have a weird bug that prevents me from watching online videos (Youtube, Vimeo etc) ONLY while playing Beamng. It's hard to describe but what's happening is the video will play and then jump back 30 frames and then skip forward to where it should be and it'll do this 3-5 times per second making any online video unwatchable. it ONLY happens when playing beamng. I have tried to record it but as soon as I start my screen recorder the bug disappears. I don't know what could be causing it but it seems like it just started happening after this last update. I have watched videos in the past with Beamng open on another screen without issue (as recently as 3 days ago) but now I can't. I have the most up to date graphics drivers for my graphics card and even tried backdating them to an earlier version with no success. I tried updating flash, reinstalling my browser and trying a different browser with no success.

The only constant element has been Beamng so I am quite sure it's the cause.


Specs:
EVGA SLI-3 Motherboard
Core i7 950 @ 3.06 Ghz
24 GB DDR3 1600 Mhz
EVGA Nvidia GTX 590 Classified

Any help would be appreciated.

 

The GTX 590 is a dual GPU card. My guess is it's related to SLI. If you can, try and recreate the problem again with the 2nd GPU disabled (if that's even possible?).

 

I have SLI disabled in order to activate all 3 of my displays and the bug appears on both GPUs independently.

Edit: It's definitely Beamng (or some interaction with it) because if I minimize the game while streaming a video the bug stops until i bring the game back into focus.

 

wonder if it's something to do with Windows Aero delegating lower priority to windows that aren't in focus. You can see the same thing happen if you put BeamNG into windowed mode and bring something (like your browser) into focus on top of it. You can see Beam running in the background at a significantly reduced FPS while your browser functions normally.

 

Yeah, not super sure. Just want it to stop happening
