Windows 7: Good ping but extreme lagging in Battlefield 2

Good ping but extreme lagging in Battlefield 2

Hello everyone,
I have just installed "Windows Seven Pro" ( via MSDN ) and i am experimenting some stranges lags.

While i am playing to Battlefield 2, i have some kind of lags like mouse lagging very visible on fast movement. It's like teleportation in some way ...

Nevertheless, i have a good ping ( < 50 ms ) and also a good config ( q6600 and a gtx275 ).

I have installed the game on an other partition with Windows XP, and all is correct with it.

So i think there are potentials reasons :
* Windows 7 manages the network differently than Vista. So a tweak could correct the problem.
* My network controller may not be 100% compatible Seven. It's a basic Realtek RTL8168 provided by the Gigabyte P35-DS4. A patch could also correct the problem, but i haven't enough hope to see it one day ...

This problem has been seen only in BF2, but it may be reproduced on other games i think.

I have also tried to update punkbuster, reinstall the game, tweak the network card ( disable autotunning ), tweak windows pagefile, but it has not worked ...

My graphic and network drivers are updated. This problem only appear online, no problem related on offline mode.

Well, all ideas are welcomed ^^

Best regards,

Is it a USB wireless adaptor your using? My desktop lag like hell with one but my laptop runs perfectly smooth.

If you have a LAN cable then try that otherwise make sure all drivers for everything are updated and check the processes running in the background. Make sure nothing is sucking bandwidth.

It doesn't sound like a connection issue. but more of a driver issue.

Hit the ~ key (` + Shift) and type in renderer.drawFps 1
That will show your current fps.

It may also be a compatibility issue try running under compatibility mode.

P.S. Check out This site. It contains a list of battlefield two commands that may help you out.

@QuackPot : It's a Ethernet integrated chipset (cf my first post). All drivers are up to date and nothing is sucking bandwidth. I have tested BF2 with Vista and XP on the same machine and on the same conditions and all is fine with them. That's why i think it's a network issue ( bad compatibility with NIC or Motherboard ? )

@mckillwashere : I will take a look to this website. Nevetheless, the graphic card doesn't seems to be the problem. The game work perfectly on offline mode.

May you have some network tunning command to recommand me ? I think this should help.

I wasn't able to solve it, had to sell the game. I hope you'll find what you're looking for there.

@Mikaka : I haven't any framedrop in my game. I can't explain very well the problem but it look like packets drops.

Well for example :
I am making an 90 mouse movement to the right.
My player is making the 90 movement to the right. Well ok, that's nice.
But, immediatly after, my position is reinitialized to 70 (or something).

In my opinion, i think the process could be slipted in two part.

The first one is the 90 in my computer. My computer calculates the movement ... and i see immediatly the result ...

The last one arrive immediatly after and consist in a process of synchronisation between the server and my computer :
Date are sent to the server, server acknowledge data, send results to others clients and synchronize my computer with received datas.

Here is the problem, it's seems all data are not correctly sent or received. Maybe a bad rate tweak, i don't know how to correct it ...

Another solution try making sure BF2 is in the firewall exceptions, or disabling the firewall then try playing online.

Another option I found just reading other forums, it may pertain to this one as well. (even though its for counter strike.)
This is it.

@mckillwashere : I have disabled my firewall to test. But the problem remains ...

It's possible that the problem is general but it may be difficult to see for an occasionnal Battlefield gamer. Nevertheless, it is very annoying on high actions scenes ( with fast movements ). On slow actions ( snipping for example ) the problem is nearly invisible.

Maybe windows seven is not able to sent too many packets at once. Why not ? It make me think about the TCP Congestion Windows ( tweakable by netsh interfaces autotuning ).

One precious remark:
The TCP autotuning is setted to "highly restricted" on Windows Vista and it's "enabled" by default on Windows Seven... Nevertheless setting it on "disabled" doesn't resolve my problem ( unfortunatly i thought that was THE solution ... but not )
