The shadows flash when I turn the camera.
It's difficult to explain, but part of the decor turns black a few milliseconds quite often.
No problem on the normal game, I have an nvidia 1080 with updated drivers / windows 10 / 2560108060hz with vsync.
And the problem remains in Low/High/Ultra detail with TAA or not, with TXAA or not, and FXfidelity or not.
Regards.
