Valve throws over 3400 CPUs and AI at the CS: GO cheating problem and it is working

Back in February last year, we reported that Valve is training AI to combat cheating in Counter-Strike: Global Offensive (CS: GO). The deep learning system was already implemented in its first iteration at that time and since then, it seems like the system has grown quite a lot. Valve obviously has a lot invested in the game and the fight against cheaters is important valuable work.

I, for one, do think the number of cheaters has been lowered as you don’t see posts about cheaters popping up every day anymore, but how is Valve doing it? At the Game Developers Conference (GDC), John McDonald, a Valve programmer, spoke about how Valve is using the deep learning system, known as VACnet (too close to Skynet in my opinion!) to fight against cheaters. This is according to a report by PC Gamer who attended the event.

According to Mr McDonald, Valve decided to tackle aimbots first as they are easier to spot and as VACnet learns, the better it becomes. Currently, the cheating problem is getting better, as Mr McDonald notes:

Deep learning is this sea-change technology for evolutionary behaviour. We think that it is really helping us get developers off of the treadmill without impacting our customers in any way. Our customers are seeing fewer cheaters today than they have been, and the conversation around cheating has died down tremendously compared to where it was before we started this work."

Valve is throwing a lot of power behind VACnet. At the moment, 1700 CPUs is working 24/7 to take the fight to CS: GO cheaters (there are roughly 600,000 5vs5 CS: GO matches being played each day), but as you can see from the image below, there is a lot of room as the game grows.

Speaking about convictions when reported by players compared to VACnet in Overwatch, it looks like the system is working very well, as Mr McDonald explains:

"When a human submits a case to Overwatch, the likelihood that they get a conviction is only 15-30 percent, and that varies on a bunch of factors, like the time of the year, is the game on sale, is it spring break. There's a bunch of things but the point is human convictions are very low. VACnet convictions are very high, when VACnet submits a case it convicts 80 to 95 percent of the time.

It is absolutely fantastic to hear that Valve is not only tackling the cheating problem but doing so well and the system is sure to get even better with time. I just hope it doesn’t grow into a whole Skynet situation because nobody has time for that.

What do you think about VACnet and have you seen a decrease in cheaters over the last year? Let us know in the comment section below.
