Hud I've downloaded (Optivex hud) doesn't allow me to zoom in/move the character about in the loadout selection screen, normally using left click/right click and middle mouse button lets me move the character around e.g soldier.
It works as normal with other huds, what file do I need to fiddle with since it's probably been disabled by the hud maker somewhere.

No, although turning it on does give more input lag.

I’m having some trouble with running in windowed borderless. I feel input lag or a low refresh rate is the only way to describe it, are they’re any settings to change or optimise to fix it?

Ah I did, fixed it! Thank you so much

I've got the right viewmodel settings; tracers are enabled; tf_weapon_scattergun has the right bullet tracer and I have no vtf crosshairs yet only on the scattergun, only one tracer round fires instead the normal ten pellets. Only thing that could effect it would be nomuzzleflash but removing that changes nothing. Help?
