Destiny 2 will not go into full screen mode on my PC. When selecting full-screen mode from the video menu an applying the changes, the screen refreshes as if changing modes but remains in windowed mode. Tested at all resolutions. Ive already deleted cvars and restarted computer. Win 10 Home Clean install Lenovo Y700-15isk 16GB RAM GeForce GTX 960M 4 GB GDDR5. 1TB SSD
