Diablo II + Vista = Lag

Hello I have a problem! I have windows vista on my pc and I started playing
d2 again and I get terrible delays when on battle.net. Single Player works
fine.

Basically I get random lag spikes when doing almost anything. Picking up
items, teleporting, clicking on portals just about anything you can imagine.

What I have done so far...

-Used all compadibility modes and other settings under the .exe properties
of the game.
-Updated Drivers.
-Ran in Window Mode.
-Used both video modes and even glide wrapper.
-Installed XP on Microsoft Virtual PC 2007 (Still getting the lag)

There is a ton more stuff I did I just cannot think of it all right now.

I have good FPS in game and my PING is good as well. SO WTF LOL

The game will work fine for maye 5-30 seconds then get a spike or maybe it
will spike all the time its random.

My Specs
Asus Notebook g2s
2gigs ram
geforce 8600m
intel core-duo 2.2ghz
OS Vista Home Premium 32bit

I would just install xp and wipe vista but I think it will be hard to get
drivers for my notebook.

Please help!
