I'm at work - can someone give it a whirl and see if this would is of any use with Blitz proggys?

Very helpful, thanks for the post.

Anyone get these to work? NVPerfKit does nothing and the GL debugger thing just crashes.

Check that you have required stuff:

-Nvidia GPU (>GF3, >=GF7 recommended)
-83.50 or later drivers (instrumentation enabled)
-DX 9.0c
-Windows XP

sorry but i don't have any graphics card, at all in any of my crappy computers

You have a braille monitor?

How do I enable instrumentation? When I try to install the drivers, they tell me I have to uninstall my current drivers...don't really want to.

The link posted has DL links for user guides etc..

He probably has a graphics card in his other non-crappy computer. ;-)

(There's plenty of situations where you don't need graphics. A headless computer works just fine as a file server, or for remote desktop stuff.
