Wii sports perfs

Hi !

I've compiled Dolphin for my Kubuntu Karmic 64bit with OpenCL following this method (it's a mix of two wiki pages, hope this is correct) :

* Step 1 : Getting Nvidia Open CL enabled drivers :

- First I've deleted old drivers

Code:

sudo aptitude --purge remove nvidia*

- Then I get the new drivers

Code:

mkdir /tmp/driver
cd /tmp/driver
wget http://developer.download.nvidia.com/compute/cuda/2_3/opencl/drivers/nvdrivers_2.3_linux_64_190.29.run

- Drivers Installation

Code:

sudo service kdm stop
sudo sh ./nvdrivers_2.3_linux_64_190.29.run
sudo service kdm start

* Step 2 : Building Dolphin

Code:

cd /usr/local/
sudo aptitude install subversion scons g++ wx2.8-headers libwxbase2.8-0 libwxbase2.8-dbg libwxbase2.8-dev libwxgtk2.8-0 libwxgtk2.8-dbg libwxgtk2.8-dev libsdl1.2-dev nvidia-cg-toolkit libxxf86vm1-dbg libxxf86vm-dev libxext6-dbg libxext-dev libglew1.5-dev libcairo2-dbg libcairo2-dev libao2 libao-dev libbluetooth-dev libreadline5-dev
sudo svn checkout http://dolphin-emu.googlecode.com/svn/trunk/ dolphin-emu-read-only
cd dolphin-emu-read-only
scons opencl=true flavor=release

Dolphin works well, I've tried it with the only game I have : Wii Sports. My hardware is a Pentium E5300 Dual Core, 2GB RAM, and Nvidia GeForce 8400 GS GPU with 512MB GDDR2.

I have about 25fps when playing tennis. The game is playable, but slower than on Wii.

With this hardware, can I speed up the game ? Is there a bottleneck with my GPU or my CPU ?

Is there some tuning I can do ?

Thanks in advance for your advices.
