Old thread, but I’ve been searching this one recently.
My old setup ran FS19 great with VorpX. Never any issues. Upgraded from a 1060 to a 3070, fresh install of windows, and suddenly I get these same stuttering issues.
I tried almost everything to get it to work, and finally stumbled upon something interesting.
The only settings in the VorpX menu that made any difference to the stuttering for me was the inverted X and Y settings. They were both ON, which works for the game, but causes stuttering for me. Turning them both OFF makes the game silky smooth, but with the obvious issues of having my head movements all reversed… which is trippy.
Not sure how to fix it now…
