DirectX 9.0L

With inquirer stuff I usually do.

I woulsn't be surprised to see a version of Direct X with Shader 4.0 on XP but there are quite a few DX10 features I can't see migrating OS.
 
That would be cool. Reminds me of when I got a 3rd party driver for my pci voodoo 3 3000 that let me emulate T&L stuff (albeit very slowly...) back in the late '90s.

Unfortunately I think the idea is that 9.0L would let you use SM4.0 in XP as well as vista if you have SM4.0 capable hardware...
 
One of Vista's main (well, pretty much only) selling point is DX10, so I can't see this allowing you full compatibility with DX10 games on XP.

As you could quite rightly expect, Windows XP and DirectX 9 are still going to be around for some time yet. Officially Windows XP will cease to be supported at the end of 2006, but that doesn't mean it'll just vanish off home users machines (it may well vanish very quickly off corporate networks though). Application compatibility is a big factor in a new OS such that DirectX 9 applications built for Windows XP will still work under Windows Vista, and there will even be an updated version of DirectX 9 to take advantage of the new driver model in Vista ("DirectX 9.L").

not impossible just highly improbable :D

the latest 3rd party voodoo drivers running doom3 is a testiment to that ;)

Actually I think it's less improbable and more staggeringly inefficient. As far as I understand the new hardware will allow for things that just aren't practical for today's equipment. That's not because it can't be forced to process it, it's because it would use an extremely inefficient method of doing the processing. It's actually like ATI being able to do HDR and AA at the same time. It can do this because the archetecture doesn't get raped when running both at the same time. An nvidia GPU don't have a method of sharing the workload evenly, you'd either get stopping and starting or, as we experiance, just one or the other.

The Voodoo case is a good example though. The cards weren't exactly pound for pound THAT much less powerful than the competition, but they weren't designed for the direction the games industry went. The result was trying to do things the hard way.....which, as the Doom 3 case clearly showed, was too inefficient to viable.

I'll try and think of a metaphor.
 
Isnt that just SP1 for XP wont be supported at the end of 2006? They cant just wave goodbye to XP for good now and not update it anymore.
 
how silly are you lot? look at call of duty 2, it can drop all the way back to direct x 7 mode. i really doubt that crysis will have as many sales as they plan to have if they release it for dx10 only. and same goes for all other games. if thye dx 10 only then chances of them selling will be very slim.
