try updating your graphics drivers to an OLDER version like older than September of last year, there is a bug with the Nvidia 200x drivers they made recently causing a lot of problems.

That did it!!! I mean I can’t be 100% sure yet, but I installed driver version 190.38 (from July 2009) and was able to cruise the universe for hours without any errors.
Thank you SO MUCH for that hint!!
