I'm having issues with my installation of World of Warcraft and I could really use some help. The game is installed and playable after much try and error. The issues I'm having now are: ridiculously low frame rate (2-5fps on average with spikes up to 10-15fps), getting disconnected from the server fairly often when hopping a boat or taking a portal somewhere. I have made the regedit changes already and that did nothing for my fps. I have also added to or changed entries in wtf/config.wtf, this also did nothing for my fps.
I originally had WOW installed on the same machine while using Windows XP and I never had a problem with my fps or my connection. The only thing that has changed since then is I've lost Windows and am currently using Ubuntu 8.04. I don't know if it's a compatibility issue with my video card and Ubuntu or if it's an issue with Wine. I'm running the versions shown below because I had read somewhere that they were the ones to use as opposed to the most recent versions.
Thanks for any help you can offer.
