3.0.2 nurfed my computer?

Hey guys, I'm new here. I've only been boxing for a few days now, but I do apologise if this is in the wrong spot or something and I've honestly tried to find an answer on the wiki/other threads.

Okay, now that I've said that.. I have a few problems and any help/suggestions are appreciated =].

1)
Prior to the pre-wotlk patch my computer (Asus G1 laptop) was able to run 3 wows comfortably but now it feels like my computer has literally got a nurf.
I can run a single wow at 80fps but as soon as I open up a 2nd wow (tried it both through keyclone and manually) my fps goes down to 8. I'm curious if this is a hardware problem? Or is it all the new content in 3.0.2? or something else completely......

2)

[s]Whenever I change my ingame video settings in WoW (while running keyclone) it will exit the keyclone window of WoW and it opens up another WoW window (this one is not connected through keyclone... so i cannot control my clones).

Also all the video setting I change keep resetting to the maximum setting whenever I load up WoW. Which makes things annoying because I want them to be at minimum for when I'm boxing.

EDIT: After already trying the "run as admin" solution a thousand times yesterday, I decided to give one last crack at it today... So running wow.exe as admin actually worked this time, and I cannot exaplin why it didn't before.

regardless, problem No.2 has been solved. =]

Any help/advice/suggestions are greatly appreciated, I have been trying to fix all this on my own for the last 3 days...

Cheers,

How did you have the shadows enabled on prior ... I noticed on my main PC that when everything was set to max I could no longer hold 30 FPS due to the shadows...

umm, prior to the patch...

I'm not 100% sure on what each exact setting was, all I remember is that I had everything on the highest possible...

I don't think I can test if I get my normal framerate back up if i change the shadows, because all the settings never save... So I can't actually change any settings...

make sure your video card drivers are up to date

sometimes with new patches it makes your video card act up

I had to turn shadow quality on low , even when I'm running just one instance of WoW, that video setting for some reason melts my computers performance. I'm running a usual 100+FPS in my main window (When I play my main account, non-multiboxing), as soon as I turn it on high, my FPS plummets to like 10 or under. Make sure that it's set to low on all your instances.

BTW, my computer runs Crysis fine with most setting ons medium to high, so I would have thought that shadow quality in WoW would be cake, perhaps that setting is bugged or something and is causing a massive performance dump, as I've read that a lot of other people experience decreasing FPS with it on high.
