HELP: Random stutter in every onlinegame (GT72S-980M)

I got my GT72s last week and I cant play any online game cause of random microstutter...

did clean install (win10-64bit) on new SSD newest Bios/EC, newest driver from MSI support site.

Offline games like Dragon Age Origins run perfectly fine.
But when I play LOL or SW.Battlefront I get random stutter every 20-60sec, unregularly.
I am going crazy guys.

Its always a tiny "jump", "stutter".
In Battlefront I sometimes run into an invisible wall on a free field, then my character "jumps" ahead.
I tried so much: deactivated Nahimic, KillerLAN processes, turned down details, deactivated privacy policy.
Ran in highperformance mode, green mode etc...
My WLAN-quality is always good (>90%), fps always ~75fps, 75hz.

pls help me. Otherwise I will give this wonderful notebook back.
It has to do with WLAN/network options as offline games run fine all the time.
maybe something going on in background?

My other notebook with GT650m runs LOL perfectly fine, so its not my inet-connection!

pls help

 

If you have the stock wireless/lan card have you tried just installing the drivers without any Killer software? You can grab just the drivers off the Killer website

 

Have you tried the LAN port on the NB? Have you also tried installing Killer driver only without the software suite?

Definitely install the latest killer drivers. They help a ton now, and used to be very unreliable over a year ago. I had issues with lag spikes with Overwatch that went away with the newest killer drivers.


Don't install the ones on the MSI site, go for the killer site.

 

or get an intel NIC it is cheap

 

Don't waste money if it can be resolved with a driver update though. Killer WLAN itself is very good.
