I get this only in BowlMA. Usually seems to be when leaving a ship gun or GV, but can't duplicate. Exiting the MA and returning corrects the error -- for a while.
Updating vid driver didn't seem to help.
Currently on that map, and am getting that error a lot, to the point that I had to turn off system messages. I have a GTX 1070 8GB card bought in February, with Nvidia driver from that time period, Version 21.21.13.7866 (version as recommended for Alpha 2.6.3 of Star Citizen).
So I've attached my Dxdiag, but how do I "send it to Scuzzy" for comment? I PMed him, referencing this thread.
