[Wine] Baldur's Gate slow after upgrading Linux Kernel

[Corvus]

I'm running wine 1.1.2 on Gentoo Linux.

When playing at least Baldur's Gate I and Baldur's Gate II with Linux 2.6.21 kernel it does run smoothly but changing the kernel to any newer version does the game to run slowly.

I have been checking the config of both kernels, and I have tried to get the same in them. I have a GF 6600 GT and nvidia 173.14.09, but I don't think it's the driver because I have redone the xorg.conf file some times.

I don't know where to look at the moment, so I wanted to know if anyone has the same problems or if anyone has an idea to try with.
