My system specs are on my gametracker, which can be viewed here. Played last night. And noticed it did it, albeit briefly, on muttrah std.
I'll keep noting the maps it does this to me on. I'll see about making a bug report on PR forums when I have time.
I do also run a full SSD rig, in raid. Needless to say I have great load times on pretty much all games. Never noticed this issue before (Fake deadscreen) until recently after the server got reset.
Even when I had PR on a HDD it didn't fake a deadscreen like this. This is definitely new to me.
I do know about the map loading buildings, Kashan comes to mind because you can literally watch the buildings appear at the beginning of the round at end screen. This issue might be related, but it's not the root.
