hi all. ok now ive checked the card for all the display modes that it supports with their respective formats. now after i get the list. do i have to check each display mode for HAL and Multisample support or can i just check the highest supported display mode and assume that its true for the lower ones? or something like that? thanks Al

I assume you''re using DirectX 8? In that case, there is a 1-to-1 mapping between "devices" and "adapters". In older versions of DirectX, you could have multiple HEL devices, one for each adapater installed. But now each adapater (i.e. physical piece of hardware) implements one (and only one) device. Basically, for DirectX 8, "adapter" and "device" are pretty much interchangeable.

That may not have been explained all that well, but basically it boils to the fact that for any given device, all modes / capabilities that it reports are supported by the underlying hardware.

If I had my way, I''d have all of you shot!

I''m still laughing over the topic of this thread.

With all the work on D3D enumeration I''ve ever done, I''ve never had a quick question..hehehe

At LEAST Dx8 is a bit easier to enumerate than previous versions...ugh.
