Hi TL.

Whenever I play Coop with my friend I get absolutely huge lag spikes. We failed more than half the chambers repeatedly because of my lag issue. We finished the coop today and even the credits lagged massively and I was on the verge of being disconnected.

It's not my internet. If I close portal 2 I can immediately play SC2 or watch youtube or even play TF2 at < 40 ping. This lag is very annoying. I'm talking about beginning to walk somewhere then being teleported back to where I was then skyrocketing forward and off a platform.

Any ideas guys?

Oh it's not my computer either, at least it shouldn't be.

Intel Core i7 2600k @ 4Ghz
nVidia GTX 570 OCd
4GB Kingston Hyper X

As you can see well and above Portal 2 requirements.

oh in the computer settings you´ve to enable erm... i just know it on german, Eingabe-Geräte... maybe input-hardware, or just input-media or something like this, steam always opens a link window when running portal 2 that guides you to the meant settings, otherwise its a air-circulator with too much dust inside...
the 1st point was my problem.
i use a macbook
systemsettings>input-help"?>mouse - trackpad? google it

Could check to see if it is overheating. I had a similar problem in single player and cooling it down solved the problem. If you are teleporting backward however, it would seem to be some kind of connection issue.
Would you kindly?

There are a lot of things you can check if you enable developer console which could potentially diagnose your problems. Since portal 2 is made using the source engine all you need to do is look up articles on how to optimize connection for source engine games. Basically there are like 5 or 6 different settings you can play with that I can't remember off the top of my head that can help with spiking. Just search around a little bit and I am sure you will find a million articles that can at least help you find more info about what the issue is.
