When I was using my old computer it was about 30-45fps then I would experience very bad hit lag and swallowing of bullets as well as frequent transients when driving a vehicle, i.e. the client and server were out of sync as well as half a second delay when using PIP scopes. Now that I've upgraded my computer to 80-120+ FPS the phenomenon has diminished to varying degrees, and the very bad hit lag has almost disappeared as well as the desynchronization when driving the vehicle off-road. These are my conclusions from playing on the same server. Maybe you guys need to take a good look at the code
