Yes that's literal, not a comment on the game. This didn't happen in my forays in the alpha but after 30 min following the tutorial - going up and down buildings searching for the elusive green waypoints, I found I had motion sickness. Now I play lots of games and this has only happened before in Half-Life many years ago.
I think the reason is the really bad frames per second I'm getting. I have a i7-9700 with 32 GB of memory and a GeForce GTX 1660 Ti. DU is on my hard disk rather than my SSD. I've tried multiple resolutions but it doesn't seem to improve the jerkiness. I am running Microsoft Flight Simulator in 4K without a problem, although that is on my SSD.
Anyone have any suggestions to improving my frames per second?
