I keep for time to time getting a black screen when I go on foot from the ship or the SRV. I try the Tab key but nothing work. I have to disconnect and reconnect to fix that. But the thing is that when you disembark on freezing planet you better get reconnect fast because your guy is stuck on the surface and waiting for you. It's make the on foot (witch is not already great) not funny at all. Update and file check done and nothing have changed.
