[Wine] World of Warcraft - Ubuntu ... Low Framerate

[Valek]

Hi, I'm a newbie here, so please don't threat me too bad.  :D 

I wanted to ask you .. Yesterday I installed Linux Ubuntu 8.04 (Hardy) on my PC, it's the first Linux OS I use on it and I'm pretty confused, but I'm trying to make it work anyway.

I installed WoW, using this FAQ https://help.ubuntu.com/community/WorldofWarcraft. I followed it, step to step, except for the installation of Wine, which I installed manually by downloading a 1.1.6 version for Ubuntu 8.04.

I had problems with my NVIDIA GeForce Go 6200 so I installed a NVIDIA driver, NVIDIA-Linux-x86-177.80-pkg1, which is meant to be good for the NVIDIA 6 Series.

After all the FAQ steps and the driver installation I ran WoW, and everything went well, except for one thing. Low FPS, not too low, certainly not unenjoyable, but I got a lot of friends with an Hardware identical to the one I have who run WoW on Linux, and their is graphically wonderful, with High FPS. 

I would like to know if I made a mistake while configuring the game, or something like that.

My Hardware (I have a laptop):
Intel Centrino 1700 mhz
512 MB RAM
NVIDIA GeForce Go 6200 w/ TurboCache Technology

I added in the config.wtf file the following lines:
SET ffxDeath "0"
SET ffxGlow "0"
SET M2UseShaders "0"
SET Sound_SoundOutputSystem "1"
SET Sound_SoundBufferSize "150"

... By the way, I didn't add the line SET gxApi "opengl" 'cause it gave me only a lot of problems; I wasn't able to reach anymore the bottom of the screen, and the FPS was a little more slow.

If I set the lowest settings for background, textures, etc, I can play with a decent FPS, but the price is high ... Is there anybody who can help me ?  [Crying or Very sad] [/url]
