I recently purchased a Western Digital Mybook usb 3.0 external HDD. I noticed when I ran X Plane 11 that I was getting a lot of lag and jitter. When I looked at the frame rates they were bouncing all over. I turned graphics settings down and enabled Vsync, but that did not help. X plane was running fine on my C drive so I moved it back so now everything runs fine as before.
I also fly DCS and have not had a problem running it off the external drive. Both games are steam versions.
Is it possible to run X Plane off an external drive ? Games now take so much space that I run out of storage too quickly. X plane I think is uniquely demanding in term of resources so the problem may be game specific.
Has anyone had success running X plane from an external drive ? I would like to be able to do so if possible.
One thing I should mention. When I ran a file integrity check when I moved X plane to the external drive there were some files that needed to be fixed, however, Steam did not fix the files when I ran the integrity check again.
