Windows 7 Lag issuesFollow

Found this repair and so far it's working for me. I'm not sure if SE has made any other updates, but i've been using this for couple months now and I haven't bee D/C once, aside from Server Crash etc.

Run: regedit
Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile
There will be an entry for network performance throttling, default value is 10; set it to FFFFFFFF hex (willl look like 0xFFFFFFFF to the right of the entry)

Since Windows 7 is defaul to 10 packet transfer max and FFXIV experiences higher transfer rates at times it causes lag and d/c. I noticed higher kbps transfer now on my Network Meter so it seems to work. Let me know if this helps you out.

EDIT: If you are not familiar with the Registry and don't feel comfortable at doing this, DON'T. You can really mess things up. Make a Restore Point and Backup your computer before attempting at the least.

I wish I was familiar with this stuff cause I been getting some dumb lag and crashes lately

When it comes to sitting around not doing anything for long periods of time, only being active for short windows, and marginal changes and sidegrades I'd say FFXI players were the perfect choice for politicians.

I might have to try this, I r0 a lot and then come back without d/cing. It's annoying.

Has anyone else mucked about with this? Curious to your results. I researching this I found a few articles.

One addresses NetworkThrottlingIndex and SystemResponsiveness.

I think I may have a go with this on my secondary machine.

If I experience very positive or negative results I will post an addendum to this.

Dunno if it's coincidence but a before and after and I lost .8mbs on speedtest download with 0 change to upload. HOWEVER after doing this pingtest showed way less fluctuation and 0 packet loss. I went from B to A on Pingtest.

Granted it's more or less peak net time so that could be the reason for the slower download speeds. My ISP is crap. I haven't had a chance to see if I notice any difference in game. I wasn't really crashing too often anyway. Maybe 1x per month other than the prior party/LS check followed by crash issue and some lag crashed when running through certain sections of town.

From minimal testing it seems certain things like multiple youtube downloads while uploading pics to facebook is a bit snapier


The link you provided I think has to do with local networking, and it's for Vista. Considering MS is bug testing cutomers in that link I would assume those items were fixed for Windows 7 (which is what this thread is about) and making any changes mentioned in your link could be dangerous to non-techies with a different OS. I on't read a few postings htough so I could be wrong.

*EDIT* NM I decided just to read through the whole thing as it's a short thread without resolution, while it is referring to Vista the below has the same effect on 7 which is what the OP is suggesting.

Without any audio application I have network throughput of 96% translating to 110 MiB/second traffic to and from my linux samba server. I use 2500 (larger sizes was actually slower) bytes ethernet frame size for my gigabit network.

Setting NetworkThrottlingIndex to higher values results in traffic beeing throttled to 50% of gigabit speed.

I found that setting NetworkThrottlingIndex to 0xffffffff will actually turn off throttling altogether. This allows me to reach full 96% gigabit utilization at the same time as using multimedia applications.

It seems that the upper cap on throttling is turned down to low, you might want to turn it to 75% of full speed for example, and I'm guessing that this gets even worse for 1500 packet size, theoretically only beeing able to reach 30% of gigabit speed
