There aren't many things you can do to make the game faster except buy a new computer.

Ignore the minimum,
* Windows XP / Vista 32bit/64bit
* CPU: Intel Core 2 Duo @ 3.2ghz or better
* GPU: 8600gt or better
* 1gb RAM (2gb if on Vista)
Is pretty much required if you want decent playability.
Note to any Linux users:
I made a LINUX ONLY driver that was available on page 22. Here is the link:
http://www.sendspace.com/file/ey7sos
It was the most available code at the time(just over a week ago) and I will try to post a new compiled version often so Zeydlitz doesn't have to waste his time on that and just work on improvements. Just copy the .so file from my download to the PCSX2 plugins directory.
There are other things that Linux users should do however.
32bit users (for ubuntu):
Type:
sudo apt-get install libglew1.5
and
sudo apt-get install nvidia-cg-toolkit
64bit Linux users (particularly ubuntu but this should apply to all Linux distros):
You will need these other 32bit .so files for 64 bit are here:
http://packages.ubuntu.com/intrepid/i386...5/download
Two .so files here should be copied to /usr/lib32
**NOTE: If you are not using ubuntu please use your own distros 32bit .so files to avoid any problems.
Then,
http://developer.nvidia.com/object/cg_to...#downloads
Be sure to download the "[Download] Linux X86 (gzipped tar) " and then extract. In "<nvidia toolkit extracted folder>/usr/lib" there are two .so that should be copied to /usr/lib32.
@Windows XP/Vista users
Various people made a windows driver, search through the threads.
Here's the link to one that Val352 made:

His note however was that he did not test it.
