I was editing a short for YouTube when I came across a weird delay in the gun sound compared to the muzzle flash. In other words we see the flash from the gun then it takes 6 frames (100 milliseconds) before we hear any gun shot at all.
Although this is an extremely minor issue compared to Sub-tick, I still think it should be pointed out.
P.S I was shooting a P2000 , the issue was the same with the USP-S, I have not tested every gun
