"Janus":
I need to get a new card to make some graphics effects and need a few
specifics dealing with seperate alpha blend, number of rendertargets,
supported texture formats etc, but no where on the manufactures websites can
I find so specific information.
I contacted nvidia about a specific card, which they actually make, but was
refered to the manufacturer.. odly enough. perhaps a mistake, but surely
there must be a way other than having to ask them every time one needs to
check up on this in advance.
How do I find out if cahdr x supports feature y in directx?.. without having
the card
Many features are already required for the card to be called "shader model 3"
(or better), for example, numSimultaneousRTs >= 4.
Some rules about things like BLEND-caps and Floatpoint-formats for
Nvidia-cards can be found in their "GPU optimization guide".
There's a d3dcaps-database somewhere on the net, but I don't have a
link to it.
And finally there's a table about card-caps in the DX SDK.
If all this doesn't help, what caps are you specifically
interested in?
Gruss
