I tried that, I stuck with 4:3 aspect ratio, I tried things like 640x480 and 480x360 but when I start wow it changes back to 800x600. I even tried setting config.wtf to read only, of course then the setting does not get changed in the file but wow is sitll 800x600...

Keep in mind that I'm using my macbook pro, running osX leopard.

My plan B is installing windows XP, and see what performance I can get from that. But I would rather stay on osX
