kentGek I've had 0 luck getting rid of the delay with achievement. But the toggle of the other two are instant. You would just need to edit/re-create a VTF of the HUD crosshair in question. Which is pretty easy once you figure out the correct settings to save the VTF. I'm personally going to play around with the two vtfs and try and make them the cl_crosshair_file "" default style crosshairs with an outline on them. Bc everyone knows the default crosshairs are the best.
I would love this, I adore the default crosshairs but half the time I can't manage to see them (also I'm pretty sure I'm insane but I swear the default sniper crosshair seems off)
