any way i found some other things that might prevent lag nut need to re find how
Info from this site [here]
Ways to Decrease Lag
When in a multiplayer game, go to Menu > Options > Sounds. For best latency, you should unckeck all four boxes because that will put less of a stress on your computer for resources. Of coures that will make the game quite boring, but there's a trade-off for everything! Below is a picture of what the window should look like when configuring for Best Latency by disabling sound
Another method is to go to Menu > Options > Video. Uncheck Enable Color Cycling and change the radio button to Disable unit portraits as shown on the picture below. This, for the same reason as the Sound configuring, will also help decrease lag
Another very important thing that helps reduce lag during Multiplayer games on Battle.net is when the gaming is counting down. People are not suppose to be "talking" during that time, for that as when all the computers sync themselves together. "talking" during that time will cause a slowdown. The purpose of the 5 second countdown is to reduce lag. Please don't "talk" while the time is counting down during your next game
Also, in most Battle.net game nowadays, people are always changing the game to Extra high latency! Believe it or not, if you've ever read the note on top, changing it to extra high latency will make for smooth performance, but setting a lower latency reduces the time between when you click and when the unit responds. Keeping the a Battle.net game on Low Latency should help to improve the lag
