Hi, I know what you mean the rubberband feeling, this comes from the 45fps effect afaik , means if your framerate drops below the 45 the “frame interpolation” doesnt kick in, you turn around look into the sky were the polygons are less and bang it kicks in again, you can try to counter it by turn off vsync and all the other stuff lowering the fps. I do not own Mirros E. but I have this in other games too. A good indicator would be, how runs the game without Vorpx, if you have stable over 100fps
in your settings then its a good chance it will run fluid in g3d. Also theres an option in the Vorpx ingame menu were you can play around with the frame sync? never tried it.
