If I try to press the fullscreen button in Crysis it just crashes. When I start the game again it is still windowed. Is there anything I can do to fix it?
I use:
Windows 10
Nvidia Geforce MX150
i5-7200U

I actually fixed the problem myself. For some reason you can't go full screen in the main menu. But fullscreen works if you go in fullscreen when you've started the game.

I have to run it in a full window screen. I get occasional crashes, blackouts or weird glitches periodically if running in fullscreen at 1920x1080.

My System:

AMD FX8350 (Stock)
16GB (2x8GB) Kingston HyperX Blu DDR3 Ram
MSI 990FXA-GD80 Mobo
Sapphire R9 380X Nitro 4GB
ASUS Strix 7.1 Soundcard (Powered)
Windows 10 Pro 64bit
