Hello everyone,

I've gotten a new pc not to long ago, and a new wireless network card with it. Ever since i've been using this my online games get super high latency when i browse the internet while playing. Obviously the easy solution would be to not browse the internet while playing, but i enjoy watching youtube video's etc and looking things up online while in game, and currently it can't play well while doing so.

I can't seem to find why this is happening. I've got a download speed of about 350mbit/s with a ping between 3 and 6 when doing anything else to other servers. It just seems to be games, specificly blizzard games that is affected when i'm browing the internet. Speedtests still show a good ping for instance.

I haven't tried downloading things while playing to see if that effects it, if that matters please let me know and i'll try it out.

I've ran a pathping to the european warcraft server(while browsing the internet) however the lag comes in frequant spikes, and it seems the pathping didn't pick it up. These are the results:

Was that trace running when you were having the problem while playing the game and browsing? If not, please repeat.

 

Are you getting frame lag or latency lag? Most Blizzard game will give you a frame rate as well as a latency meter(CTR+ALT+F). If you are dropping frames, the first thing I would try is to play the game in windowed full screen mode and check that any Nvidia streaming or overlay software is disabled. If it's a latency issue, then you may have luck using QoS on your router to give the game priority over web traffic. See here for what ports HoTS uses. For instructions, what model router do you have?

Thank you for your reply.

 

the trace was running in conditions where i would be having the problem, but i wasn't running the game at the same time, I did another one where i was running wow while doing the test, while having issues, the results are pretty simular. Slightly higher ms, but nothing like what i actualy get in game.

 

I have a tracker for my fps and latency. Fps isn't the issue. Always a steady 60 (with v sync on) the latency is usualy 3-6ms, but when browsing the internet it spikes up and down very frequantly. The tracker doesn't adjust that often so i can't realy tell what the numbers are, it's giving an average of around 500ms, and it feels like it spikes between 10ms and over 1000ms.

 

I tried using QoS after your suggestion. I'm using a nighthawk r7000 (and a asus PCE-AC68 as my network card), instructions were available online. Sadly it didn't seem to change anything, thank you for the suggestion though. This new pathping i did was also done with QoS  on for warcraft (and again, done towards the warcraft server).

It's hard to say. There is a increase in latency at hop 4(80.249.208.83) which is the last hop on Amsterdam public network before hitting Blizzards servers.  However, most of the latency is occuring inside Blizzards servers. Also, it's getting to the server in 22ms, which is a lot less then 1000ms, so something doesn't add up. 

 

Can you describe the problem more? Does it happen with other games? Other blizzard games? Does it ever happen when you are playing and NOT doing anything else? Does the problem happen if someone else is streaming a movie on another PC on your network while your playing?

 

One easy thing you can try is to change the priority of what ever browser you use on your 2nd monitor. See here for instructions. You would have to change the priority each time you bring up a new browser window but you could use option 2 to save a shortcut with the included extension to set the priority automatically.

Looks like the issue has been resolved trikein, thank you very much for your help.

 

I tried giving the game priority, but that didn't help. I had the same issues in some other games, but mostly blizzard games. It didn't happen when doing anything else, downloading in steam, downloading torrents didn't effect it, having other people on the network didn't seem to affect it either.

 

I was looking through my installed programs and noticed my old network card driver was still installed, there was also some useless software that came with the disc from my motherboard. Some cloud storage software etc. I deleted all of what i didn't want and now it's working like a charm! :D

 

I don't know wich of those programs gave the issue, so i'm sorry if you were curious what was causing it. My best guess would be a conflict between old and new drivers. 

 

Either way, Thank you very much for your help Trikein. Even though the direct solution didn't come from you your questions and suggestions made me think of a lot of new things to try to solve it.

 

Thanks a ton,

 

Kind regards,
