nv40 won't support dx9.1

[russo121]

I've looked this at the inquierer.net - http://www.theinquirer.net/?article=13907



"...yesterday’s information that NV40 won't support DX 9.1 is completely true. And the R420 will work with 9.0c only, as there will be no DX 9.1..."

Soo...... dx9.1 will be for nv50 and r500?:confused:

[-=DVS=-]

Well is that good or bad news i can't tell..... doesn't realy matter :p

One more time, very slowly:

THERE
IS
NO
DX9.1
!!!

:rolleyes:

NV50/R500 will be... DX9.1. Or maybe DX10. Depends on Longhorn.

Better question is do both NV40 and R420 support DX9c ( PS3.0 VS3.0 ) fully ;)

If this is true I guess so. Since DX10 wont be out until Longhorn is released (which, for what I know should be 2006/2007) I guess this leaves headroom for DX9 to expand into 9.1 on the NV50 and R500 which might be 2005. Then the NV60 and R600 in 2006 or 2007 which will be DX10 along with Windows Longhorn. Wait, maybe im jumping ahead of things. Oh well it's still fun to predict what will happen :P

Anyone knows exactly what ps3.0 is?

I read long ago that ps/vs 3.0 consits
basicaly in interactuation of ps & vs (now
ps & vs should be one program sharing data
and flow) :confused:

No, no, no, no, NO!!!!

There will be NO dx9.1, there will be an update to dx9 called dx9.0c and then the next dx update will be with Longhorn and they will call it something else entirely. (directNext is what I've been hearing, but who knows.)

THERE IS NO DX9.1!!!! Say it with me, "THERE IS NO DX9.1!!!"

It's an easy concept, just accept it. :)

[russo121]

Is there a big enhancement in ps3 compared to ps2? If it doesn't, imo these new cards only brings more fps.... iq will be the same...
I'll be very very happy if these new cards brings things like cinematic rendering in real time (i don't think so).... :o

Make that the "BS Rumors Section", and I haven't heard ANYONE say "THERE IS NO DX9.1!!!" yet! :bleh:

[Skuzzy]

PS3.0 is in the current DX9 spec. No reason to release another version of DX9, unless for bug fixes.

harl,..what do you want to know? I can list the opcode differences between PS2.0 and PS3.0. Would that be of any benefit?

[Martrox]

Damn....DW....next thing you'll be telling us is there's no Santa Claus or Easter Bunny!;)

Dad: "Son, I want to explain to you something called sex."

Son: "Dad, you already told me that there is no Easter Bunny. Then, you told me there was no Santa Claus. If you're going to tell me that grown ups don't ****, I've got nothing left to live for."

:D :D

I'd like to hear your opinion on how developers will react to PS 3.0 hardware.

I'll second that. Your insights are always very welcome here Skuzzy. What do you think about Dany Lepage's comments found at B3D (http://www.beyond3d.com/forum/viewtopic.php?t=9982)?

[Skuzzy]

PS3.0 does bring a lot more flexibility to the table over what we currently have. Dany alluded to it bringing more performance. That will not be the case, in general.

Branching has the potential of simplifying shaders, by allowing programmers to write one shader to replace three, for example. But in doing so, the shaders will get a little bigger.

Overall, it will make it easier for programmers to get the job done, but I would expect little to none in terms of performance gains.

PS3.0 makes several changes. Here is a brief of the changes.
========================
Add a face register. Add a position register. Color registers (v#) are now fully floating point and the texture coordinate registers (t#) have been consolidated. Input declarations take the usage names, and multiple usages are permitted for components of a given register.

Dynamic Flow Control
The device supports dynamic flow control (if, break, and break_comp). The depth of nesting ranges from 0 to 24.

Number of Temporary Registers
The number of temporary registers supported is 32.

Static Flow Control Nesting Depth
The call/callnz/call_pred can be nested to a maximum depth of 4. Independently, loop/rep instructions can be nested to a maximum depth of 4.

Arbitrary Swizzle
Arbitrary swizzle is supported.

Gradient Instructions
Gradient instructions are supported. (dsx, dsy, and texldd).

Predication
Instruction predication is supported.

Dependent Read Limit
There are no dependent read limits.

Texture Instruction Limit
There is no limit on texture instructions.

Instruction Count
Each pixel shader is allowed anywhere from 512 up to the number of slots in the MaxPixelShader30InstructionSlots member of D3DCAPS9 (not more than 32768). The number of instructions run can be much higher because of the looping support. The MaxPShaderInstructionsExecuted cap in D3DCAPS9 should be at least 2^16.
==========================

There is a lot of potential to do more with shaders. With the gradient instructions, it will be easier to do 'fuzzy' shadows, for instance.

The big key will be the GPU's and all we can do is hope that NVidia/ATI realize shaders are going to be a big part of the future and design the hardware to make them efficient.

Next version of DirectX 9 will be DirectX 9c

Gwah?! If I recall ATI has been saying this for a really long time

[AthlonXP1800]

Yeah here will be no DirectX 9.1, here will be DirectX 9.0c!

Many of you probably didnt know Longhorn build 4052 has DirectX 9.0c so far nobody able to rip out DirectX 9.0c, it probably cos of special Longhorn version as you will need 2000/XP DirectX 9.0c version. :)

BUT NOOOOOO!!!!! The NV3X will be 100x faster when DX9.1 comes out. "lol" :D:angel2: :angel: hehehe

I guess that kills the big performance boost in DX9 there guys. ;)
