[Wine] Low Framerate in Oblivion

[valente500]

I've been getting max 10 FPS in Oblivion, even with extremely low graphics settings. Any ideas why? I didn't have any problems with running Oblivion on Windows, and even for Wine this seems quite low. I think it might be my graphics card drivers possibly. 

OS: Ubuntu 9.10 Karmic
GPU: nVidia 8600M GT
CPU: Intel Core 2 Duo @ 2 GHz
GPU Driver: Version 195 (I got it by going System -> Administration -> Hardware Drivers, and then Enabling it).
Wine Version: 1.2

I also read somewhere that ubuntu-restricted-extras might be affecting it?

Any help would be greatly appreciated.
