popcorpThat command has been broken since Love and War update I think
Geknaiircl_jiggle_bone_framerate_cutoff 0
That, indeed, is the command that used to stop jigglebones from working, but is broken atm. Fps_max doesn't do anything, only limits your fps. Only advise I can give you is either r_drawviewmodel 0, a low viewmodel_fov (not sure if it works), not using botkillers, or just leave the cutoff at 1 and play with jigglebones. Maybe we could message Valve about this? Dunno what success would that have or whether someone's done it yet.
