I've got psychonauts for the PS2 and want to buy it for PC.
I just want to know, will it work ok with windows vista?
It might. It's Windows, so it's a gamble. It's Vista, so it's fraught. I got a PS2 and play Psychonauts there, despite the poor graphics and controls, because years of fighting Windows soured me on it.
Still, here are some tips.
You can try the demo first, before spending your money.

Run Psychonauts under WinXP SP2 settings in Vista.
Patch Psychonauts to the highest version, also available from

If running a dual-core processor be prepared for choppy or overfast play. Lower the affinity for one of the processors in that case.
Update video and sound cards with the latest drivers.
Update to the latest version of DirectX.
Reboot Vista at least weekly. Reboot an extra time or two after updates, upgrades, installs, etc.
Run Scandisk a few times, then defragment the hard drive. Ignore the defragmenter's recommendations. Windows will happily focus on using the only fragmented part of an otherwise clean drive. Do a surface scan overnight. Do all this every 6 months or so in any case, or when there are problems.
One person got Psychonauts acceptably stable after problems by running Norton Disk Doctor unattended.
Please let us know how it goes, and if the controls and graphics are really that much better.
