well first of all, you may have noticed that no player is moving, if there is one, because you are not connected to the server, evident by the notorious “players ? ping ?” bug, and even if it shows ping in this case, if you look closely, it is not changing or updating, so you have definitely timed out. secondly, disable vsync. if that didnt help, its most likely your GPU software. in the worst case scenario, if we will just ignore the “players ? ping ?” situation, you are experiencing a SEVERE memory leak. i have had this EXACT scenario before - it starts slowing down (not even lagging!) in “waves” after some 5 to 30 minutes of gameplay, as it worsens more and more, until it completely BSOD’s my computer with 0xC0000409 STATUS_STACK_BUFFER_OVERRUN error code. if you had this symptom of your framerate worsening the more you play, or where your camera gets stuck outside of your car and you are unable to do anything - that is a memory leak AND a buffer overrun and IT WILL become worse - if you have watched some nintendo corruptions videos, this is something like that, except it is happening with YOUR game. this was one of my very first posts:
now, this begs the question, do you BY ANY CHANCE have that laughably deprecated UI vehicle mirrors mod? that would be an enormous coincidence AND a miracle as this mod is still OUT THERE on beamMP servers… causing memory leaks.
if you would be so kind as to provide the non-paged pool or kernel mode reserved memory size from your task manager, that would help diagnose the issue and leave a reference for the future. follow my instructions from this older post:
