Well thats basically as far as I get after deactivating "fast terrain"
When I had it enabled, the mouse cursor was jumping around in the top right forever.
As you can see, 7minutes in it never bothered to leave the base, I tried that twice, once with "open cam" and once with "third person cam".
The vm I used is handling ulb and loletal without any problems, so Im not really motivated to change anything. :/
