I've noticed this since I got a new motherboard, memory and CPU a few weeks ago - same graphics card as I've had for years. So, I have to imagine it has something to do with my rig/drivers, although all drivers (that I can think of) are up to date.

I've noticed it in Co-op and HVV. (haven't really been playing other modes)

When I say it happens often, this means it happens about twice (several seconds apart) in almost every match.

I've tried numerous changes:

- various refresh rates - 60-144 Hz

- overclock video card, don't overclock card

- various resolutions - 1920x1080, 2560x1440

- HDR on and off

- rolled back NVIDIA driver to prior release

In-game graphics automatically set to ultra - card definitely had no problem with this in the past

DX12 is off. 

Video sync is off.

full-screen

Microsoft in-game is off.

Origin in-game is on.

CPU is not overclocked.

Max CPU temp: 71 C - well within range

Max GPU temp: 83 C - well within range

DXDIAG attached.

LG 27GL83A-B Monitor is set at 144Hz and G-sync is on.

Any ideas?
