Ben Singer at U. Rochester told me that the ATI Radeon card has 10-bits
and that there is a custom driver that will actually let you access all
10 of them
.
You might email him for more info: <bens@...>.

If the drivers are available now would someone please post here to the
psychtoolbox forum either the drivers or info on where to download them ?

Due to some recent requests and 6 month long foot-dragging by ATI,
this looks to be a good point in time for me to post the Radeon PCI
10 bit gamma driver. The web page for it is :

http://www.cvs.rochester.edu/~bens/Radeon10BitGamma

As of 9/20/01, ATI still says they will have the driver on their web
site soon, but I'll take the risk and put up my copy for now. If they
do post it, I'll post a link to it from my site. The driver is
unofficial and unsupported, feel free to contact me about it but
please do not contact ATI. More details on my site. Thanks.
