I am also experiencing this.
I'm just interested.
Hi.
Full screen won't work.
Used to be that this happened all the time, and I just ALT+ENTER to get everything OK, but now it just switches back to windowed.
Setup:
- BenQ BL3200PT 1440p monitor, 60hz
- Onkyo TX-NR646 for surround sound
- i5 4690K
- 16gb ram
- win 10
- dx12
- nvidia driver 388.31
Attempted fixes, whenever I say it's windowed, assume I've tried to start or continue my game *then* ALT+ENTER to get fullscreen, too:
- Changed to Fullscreen (which it already was) in game. Switches to Windowed straight away, despite saying it's fullscreen.
- Added "-fullscreen" to startup options. Flips back to windowed.
- Forced fullscreen rendering on GPU in NVIDIA Ctrl Pnl. Either doesn't start or starts windowed.
- Forced fullscreen rendering on Monitor in NVIDIA Ctrl Pnl. Either doesn't start or starts windowed.
- Checked RenderProfile in the GamerProfile.xml and it has "Fullscreen="1" " ... Starts windowed.
- Launched with no overlays, steam off, GEFORCE Experience off, and UPlay not running. Windowed.
The Onkyo is required for sound, and thus presents as a second monitor, however this hasn't been an issue for 2 years (or however long it's been).
Will raise a ticket with you, but I'm not exactly sure how, also I wanted other people to be able to see this in case they're getting the same issue.
Will try a driver update on GEFORCE Experience.
