I came to this page searching for a fix, i see the dev's still look for an awnser.
My situation, as the bug happened twice:
Server: 77th Jsoc
Where: Tower in HQ
Situation: I was standing next to a couple of big machine guns with tracer rounds, when they started fireing the bug kicked in.
Server: 77th Jsoc
Where: Crouched down near HQ on landing strip
Situation: Multiple heavy machine gunners sitting next to me. we kicked the **** out of HQ.
upon entering HQ and standing on the building, heavy fire again happened..as wel as a big tank rolling in.. Bug kicked in.
I have the idea that it is a combination of sound and video, which may be overloading or be too overwhelming for the computer to handle.
in both situations heavy, and i mean heavy gunfire were applied with tracer rounds... screen shocks couple times, then goes into the 3fps state.
also i was, both of the times inside of a compound/building, i do not think this has to do with the issue, i think sound vs video(lots of stuff going on simultaniously) may be a cause looking at my occurrences.
