New Hack/Exploit (Lag/FPS Loss Hack) (Packet Loss)


(spookify) #1

After around 3-4 hours of awesome pubbing last night on the same server (I think) a new map was starting and 2 new players joined that I have always suspected of some sort odd behavior. And sure enough as soon as the map started I noticed that it felt like my frame rate was cut in half. The game was not crisp and it was a struggle to play.

I have also noticed this exact same thing happen in a non-casted DB Nation Cup a few months ago when I played with F8.

The links above are exactly what I experienced. Frame or Packet Loss making the game unsmooth…

I would urge players to keep an eye out for this and also SD and Nexon to be aware of it.

Are you sure that you did not just cause a performance problem during the loading screen via alt-tabbing out of the game?

I am able to cause one via alt-tabbing during the loading screen which then adds 50-100% CPU and draw time which significantly reduces the FPS amount (due to the game having a CPU bottleneck) and therefore smoothness and responsiveness.
This bug won’t go away until you restart the game, though. How long did your problems last?

Nope, I didnt Alt Tab or anything and the game was rocking with very good performance for the few hours before. The combination of Good play and suspect players makes me think there was something a foot.

Again just posting it here for people to keep an eye out for and also make others aware people might be doing this.

The Problem lasted for the entire length that these 2 players were in the pub server.

Not meaning to derail the subject but for me the alt-tab ‘bottleneck’ only lasts for a few moments, then it goes back to normal. No need to restart in my case.

Same, I alt+tab quite a lot and I get an fps drop for about 5 seconds at most then it’s back to normal.

Well, my “bug” is different from that. It is permanent and very much reproducible on my computer. But it can only occur during the loading screen.

You are describing the normal, temporary FPS decrease from tabbing back to the game. The one I am talking about is permanent and requires a game restart to fix. Even going back to main menu does not resolve the issue.

But, since this is clearly not the cause of spookify’s problems, we should not further discuss this here. Instead, we should do that over at my bug report on Nexon’s forums (contains screenshots).

Does that mean, you played long enough to see them leave and the problem gone again afterwards?
