I am experiencing a strange bug. I'm running the game at 35-40( Dev-branch ) fps but when I fire my weapon, full-auto in first person view the game starts to lag and my fps drops to 10-15 even 5 if I countinue firing, however this issue does not appear on third person view, I'm not experiencing any fps drops what so ever. I've tried almost every weapon and I get the same result every time then I switch back to stable just make sure it wasnt a Dev-branch issue but I get the same result again. Does anyone having this issue ? I think muzzle flashes causes this issue but Im not sure.
