I want to set default graphics settings in my application according to the video card memory on the target system.
I have googled this already and found some functions which work on either NV or ATI grahpics cards via extensions. However, these do not seem to always work correctly and I was thinking they might be deprecated.
So I would like to ask here:
1) Is there a reliable way of checking video card memory on any card, regardless of manufacturer?
2) Is there a way to check the video card memory that is (un)used at the moment?

Thank you in advance.
