Well, today I learn another few lesson:
1. ATI kinda suck
2. Core 2 Duo is blazing fast
3. Don't try to cook and programming at the same time or you might burn your house ( apartment in my case).
Anyhow, I fixed some stuff. I can say now our core engine is 99% complete. Even though there are still a bit far to finish client but I can see the light.
So Cheers everyone, and if you know any good programmer, please introduce them to Tatsu.
