Last night I was trying to install the driver in my home desktop as well as my notebook. I hit problem in both cases, both I managed to resolve the problem on the notebook, while the desktop is still stucked.
Therefore, let me report the performance on my Sony Vaio U3 first, here's the configuration:-
1. Crusode 933MHz CPU
2. 512M memory
3. 20G hard drive
Since it didn't come with USB 2.0 port, I used a PCMCIA USB 2.0 card and it works without problem.
I was using Y800, and the highest frame rate I managed to get is 12-13 fps, I believe that the bottleneck should be the hard drive and the CPU.
