Doom3: Will it have a separate SM3 codepath ?

[KimB]

Well, he made that quote before the NV30 hardware was actually available. Obviously he had an emulator, though, and so knew its capabilities. He just didn't know that nVidia would be unable to get a decent compiler for it out the window, or, perhaps, that the NV30-34 would have so few FP units.

 

[Ostsol]

What was JC's quote? "Doom 3 is designed around the features and capabilities of GeForce2 style products, my next engine will be designed around nv30/nv40".

Dave.. Common.. I cannot believe Camrack would design anything around the NV30.... After seeing what an NV30/NV35 does with the new Farcry 1.2 patch I would say anyone still staying those are good cards are few and far between anymore.. Unless they are just in denial.

He's not talking about the video card; he's talking about the feature-set.

 

[AlNom]

So which is it? NV30 or NV40 set of features?
or does he mean, NV30 as the lowest feature set and NV40 as the target for max quality?

 

[jvd]

I think he meant nv30x featuers .

If he starts programing it now we wont see the game till at least 2008/2009 which means the nv3x type chips should be the intergrated lvl.

Like how we now have more powerfull than geforce 1 cards built into things like the nforce 2.

Fixed.

now you got it wrong :?

daves post didn't need fixing

Sometimes they do...

or the R8500 (I've never seen one of those around actually)


2008....when we'll have 4GB memory on video cards eh?

Na . I think pcs will have 4 or 6 gbs for main ram and vpus will have 1 or 2 gigs .

But I mean. quake 3 came out what 1999 or 2000? Now its 2004 and it looks like doom 3 will come out ? So another 4 years to that and it will be 2008 .

 

[AlNom]

I think it was 1999... right at the time of UT?

texture artists and modelers sure do have a lot more work to do if they want to fill up 2GB of video memory and then some (main memory)

or maybe the original concept of Halo will be possible (exploring the entire ring without much in the way of level loading )

Yes, and that was the line over a year ago. Since then he's made noises that NV40's featureset will be the baseline for the next generation - partly because he's probably not had the time to seriously begin the reasearch on his next engine with the delays to D3.

 

[Cryect]

Heh just you watch his next engine will be designed and used for an Armadillo Aerospace space ship. I wonder how powerful his next engine for a space ship will be if he helps design another one.

 

[AlNom]

what features exactly does the nv40 have with respect to opengl?

FPblending

 

[KimB]

Well, the hardware supposedly has no pre-set instruction limits, so essentially any GLSL program should run.

 

[AlNom]

ah...... I see....

 

[KimB]

Well, keep in mind that I don't know of anybody that's tested this yet. So we'll have to see.

 

[anaqer]

So we'll have to see.

"See" I understand, but "wait"? You just got an NV40, right?

 

[Cryect]

Heh, plus you have the issue with a shader that even approached the limits of 2^16 that you would wonder if the video card locked up.

 

[AndrewM]

Dont forget that carmack was using the FX12 units which are available in the same fragment program in the NV30 opengl extension.

 

[KimB]

"See" I understand, but "wait"? You just got an NV40, right?

Yes. But I've never actually used GLSL, so I haven't yet taken the time to get a test program up and running. I suppose you could either wait for me to get around to it, or somebody else

 

[KimB]

Heh, plus you have the issue with a shader that even approached the limits of 2^16 that you would wonder if the video card locked up.

Well, if you wrote the program so that it only ran on a few pixels, it wouldn't take that long.

 

[Colourless]

If it only ran on a few pixels, what is the point.
