View Full Version : Asus G55VW - Random Lag Spikes for Games (Dota 2, LoL) Skyrocket to 2000+ ms

12-10-2012, 02:24 PM
I just recently got a Asus G55VW not too long ago (a month old) from http://www.ncix.ca/products/?sku=70924. The problem, however, is that even though I can run games like Dota 2 on maximum settings at low ping below 50, I will always at some point randomly lag spike up to 2000+ ms and this ping eventually then drops back to normal. My default network card that came with laptop is Atheros AR9485WB-EG Wireless Network, but I decided to switch to a Wifi USB Adapter (Belkin N300 Micro Wireless F7D2102).

NOTE: I have already had McFee Anti-Virus uninstalled from my computer at the start.

Here are the specs:

System Model: G55VW
Processor: Intel(R) Core(TM) i7-3610QM CPU @ 2.30GHz (8 CPUs), ~2.3GHz
Installed Memory (RAM): 12.0 GB
System type: 64-bit OS
Graphics Card: Nvidia GTX 660M 2.0GB

I am really unsure what the issue is, since I have tried switching to different USB Adapters, resetting my router, etc, but the problem still exists. Any help is appreciated!

Hmm...seems like we got the same problem...I'm a Dragon Nest SEA Online player...experiencing same spike...any online game will randomly freeze like 1 sec...in any random moment...at 1st I thought it was gpu driver or OS problem...tried many version of driver still same...tried both windows 7 & 8...still same...kinda weird, my old laptop with weaker GPU doesnt have this problem.

I'd recommend troubleshooting with DPC Latency Checker. There may be drivers on your systems causing the lag.

@shfl - did you uninstall your Atheros wireless adapter and driver from Device Manager prior to installing the Belkin? Be sure to test the Belkin driver with DPC Latency Checker.

Yeah, its really unfortunate to encounter this problem which I have no clue what's going on, though I am sure it lies on my networking side and not the computer itself.

@dstrakele - The default networking card Atheros is still on my laptop, as I simply installed the Belkin driver as a secondary wireless connection. Would having 2 wireless connections conflict with each other even though I would mainly be connecting to one, while the other is off?

There could be a conflict between the two wireless drivers. Uninstalling one while monitoring with DPC Latency Checker will help determine if that is the case.

Alright thanks, I will check it out!

Hi again,

So I just downloaded the DPC Latency Checker and to my surprise it gives me the message that "Some device drivers on this machine behave bad and will probably cause drop-outs in real-time audio and/or video streams. To isolate the misbehaving driver use Device Manager and disable/re-enable various devices, one at a time. Try network and W-LAN adapters, modems, internal sound devices, USB host controllers, etc."

The graph shows NUMEROUS red and yellow spikes going to 1000-2000us. Is there any indication of what drivers I should turn off to fix this problem? Thanks!
