Isn't DX10 software?

[StevenNevets]

If DX10 is software on video cards couldn't a modern-day video card be modded to support DX10?

just thinking.

Nope, current-gen graphics cards are just not designed to take advantage of DX10's software features.

what were they doing for DX10 screenshots months ago?

Perhaps rendered with a reference, er, engineering sample, of an 8800GTX? :laugh:

More than likely they were DX9 screenshots.

oh... so DX9 fooled me and others into thinking they were DX10 screenies?

why bother then

DX9c

DX10 is the future . . . it ultimately has 'lower overhead'.

Ok, if that was true. I'd suppose it'd be possible to emulate DX10 on DX9 cards. But the performance would be absolutely horrid because it's just something they weren't built to do.

there are no full dx10 games for at least a couple of years

all the current games -crysis, etc. - are DX9c games with some DX10 enhancements for vista and dx10 cards

everything you can do - curently - in DX10 can be done in DX9. the only advantages you're gonna get is higher resolutions, more textures and a little faster geometry . . .

[apoppin]

DX9c is the current version

 

[BFG10K]

When it arrives it'll bring some technical advantages over DX9.

No, 'C' is the latest revision that supports SM 3.0.

The screen shots were probably either with prerelease silicon or with the reference software renderer (yes, directx can be rendered entirely with software).

You could conceiveably make directx10 drivers for directx9 cards but it would suck so bad you would never want to do such a ridiculous thing. All the hardware features of directx10 would have be done with software using the pixel shaders or something and that would be super slow. The only reason a video card is as fast as it is is due to application specific circuitry. Use general purpose circuitry to emulate that hardware and you're looking at a 100x slow down.

There's no need to emulate DX10 on DX9 systems. What we need is for the devs to write native DX9 fragment programs that result in similar visuals as those produced by DX10. It may harder and require the use of some tricks/shorcuts, but to say that DX10-like visuals absolutely can not be done in DX9 would be a lie. The current limitation on graphics remains the hardware, not the API. Given a fast enough DX9 video card, I see no reason why we cant have Crysis run on it with the same visuals as those in the screenshots.
