CXBX And Videocard's

[VenomX]

Yeah i seen all this new stuff about the emu.
just wondering with game's like splinter cell
that use have vertex shaders wont ati card's have a hard time running it. because i thought vertex shaders's and pixel shaders are only on invidia cards and games like splinter cell use heavy vertex shaders just a question

Any of ATi's cards with a model number 8500 or higher have some level of vertex shader and pixel shader support (also SiS's recent cards have partial support for them.. and I believe Matrox's last card has support too...). The format is different than nVidia's, and I'm unaware as to whether or not XBox's version of DirectX has a high level shader language similar to the one present in DX9 (I think?).. if so then it'll probably be possible to emulate them in DX9, and then the driver's shader compiler will take care of the rest. If shader programs are written in ASM on XBox games then that's another story; it'll be hard to support them with any decent speed on non-nVidia cards.

see thanks like i said im not a emu freak so im glad im getting a 5900


But i still think it wont be as great as some people make it out to be. there going to be something about that xbox thats going to change the whole way it has to be emulated i think it going by great cant wait to see it. but i think we are 2 years from a almost perfect xbox and with pc bottle necks i think in 2 year we will have xbox for pc and by that time x2 should be coming. thank for the reply exo

peace

From how things are going, it's going to be ALOT sooner than that.

Well, caustik is using a Radeon 7000 series to develop CXBX on... It might be tough emulating some of the more complex features and graphics that his card does not support.

i'm glad that i'm using Nvidia , now, how bout the CD issue? :P

[VenomX]

i still dont think it going to be as soon as you think
becuase he does not have perfect emulation yet
so we still are not for sure what actully going to be emulated software and what going to run off the hardware i know it runs like a pc but i think in order for it to run good the game might have to be iso
plus the bottle necks of todays pc's he just has not run into any bottle necks yet that all it still to early to say it going to be pefect in less then 2 years
i think no one can be that perfect in makeing a %100 pefect emulation of a emulator look at n64 its still not perfect nor is nintendo and game boy they are always making updates i cant wait to see it in action but i think we are still far away from it it just my thought thats all i know im not right but im also not wrong .

This kinda emulator is just totally different than emulators for any other console ever emulated, you can't compare it to anything.

Would be nice if someone could donate him a GF4 Ti.. ^_^

I believe that pretty soon you'll be able to get a GF4 Ti 4200 for about $50. Right now you can for about $80 if you shop well (eBay's good for this)

As I said in a thread before, I'd be willing to donate my Radeon 9500 Pro with a hacked BIOS(for overclocking) once I get my 9800 Pro.

yeah but to understand the full process of emulation a xbox he needs a geforce card not ati
becuase as you knwo it runs off a gefoce card

[ector]

Exophase, interestingly, xbox vertex (and maybe pixel, not sure) shaders as being passed to directx, are the exact same intermediate binary format as on PC so most shaders should be possible to run "natively" on any gfxcard on PC

But the Xbox is practically using DirectX for its video library. . . I don't think it matters, any card that supports DX 9 will do just fine.

THANK you ector

[zerocopy]

how bout i give caustik my ti4200 and you give me the 9500 pro

SWEET! That's very nice to hear. That means Radeon 9500+ should do quite well with XBox games too?

That was for kingofc, this is for caustik. I don't suppose you have two, do you?

Hi,

The XDK compiles the shaders straight into NVIDIA microcode, instead of the GPU independent DIRECTX byte code that is normally generated.

This is not that bad, as...

We can reverse engineer the microcode to the source shader, and recompile to DirectX bytecode.

It's not as simple as "The XBOX is directx so we can use the shaders..." but it's close enough.

Cheers...

Actualy I think Caustik is "borrowing" a Radeon 9500 Pro now......

I knew it sounded too good to be true, but thanks Can the XDK compiled shader code really be decompiled into the DirectX shader language without any possible loss? Does the XDK allow for inline assembly in its shader programs? That could throw things off a little..

Well the xbox itself has a GeeForce 3 card and if i'm guessing right it's a fully supported directx8 card and the xbox is built around direcx8 standards?
So my point is that any card that is newer than the GeeForce3 can manage to emulate the xboxs hardware.
The pixel and vertex shaders is a common standard, i mean like the gf3 has(guessing) version 1.2 or something like this (vertex and pixel shaders versions).
A newer card like GeeForce FX has pixel and vertex shader version 2.0 ++ or something, and Ati cards above 8500 have shaders 1.2+ and 9500 and up series has 2.0 shaders if i'm not wrong!

So in theory Splinter Cell should run just as good on your ATI cards as it will on the Nvidia basis cards.

I also read Caustik was making his emulator on a Radeon 7000 :P if he is there would be no problems runnig the emulator with your ati cards, cuz they all use the same drivers (catalyst).
