NVIDIA control panel (or your own grapic card driver) -> 3D setting -> limit your FPS target (If you have 144hz monitor, 144hz) and your .DLL file too
However, I (I think We) can't solve that knobs not work on Valkyrie mode. I just use my keyboard to knob control
: SpiceTools config -> VOL-L left, right, VOR-R left, right each O,P,[,] (<- you can use what your favorite button :D)
to select sometings
btw you can use your knobs in the game play. just select/move can use only O,P,[,] for me
