Reducing latency

[BobGnarly]

That's WoW for ya...where a simple registry change, or running a completely unrelated program can vastly improve performance for random people lol

heh, yeah. How they went this long without figuring out that Nagle on a latency sensitive application (like a video game) is not a good idea is a bit of a head-scratcher.

This worked really well for me. My ping with 1 client is typically 70-100 ms. As I added more it would always creep us, usually to about 250 ms with 5 clients. Now I'm able to run 5 with pretty normal latency, maybe slightly higher but still < 150 ms. Ftw!

Btw, for you Vista users the hotfix above is in SP1.

I just gave this a shot using only the TcpAckFrequency and it seems to have taken my ping from in the 250s to in the 190s for a single instance of WoW (Charter cable is terrible btw). I couldn't find the folder for TCPNoDelay so I didn't bother with it.

It's the same registry key (folder). You have to create a DWORD value if it's not already present.

I dont even bother to play if my latency is over 70ms, ususaly its 50 or so. I am in San Jose, Ca and the Servers are in San Deigo for EQ I think, 6 Meg dsl. I have two 1 gig connections to the router on my main.

I used this don't know if its any good or not though but it did seem to help

I live on the east coast, play on a west coast server. It's a great day when I'm at 200-250; usually I play at 300 or more. Honestly it isn't a big deal. Maybe one day I'll play from a low latency area and notice some huge difference, but I have zero problems playing at 300. It has to be over 400 before I notice, and over ~700 to really become unplayable.

Back pre-TBC, the top DPS in our Naxx guild played at over 1K ms from Taiwan. Spell cancel-queuing ftw!
