Egg on ATI's face?

at NV40 launch the Crytech guy refered to everything as "PS2.0 and PS3.0" was necessary..
Which leads us to belive that the "SM3.0 mod" is nothing but content update with SM3.0 support..
not SM3.0 exclusive.. you just dont want to run it on "todays" PS2.0 hardware..
Altho running it in PS2.0 on R420 is prolly very possible at similar rates and visuals as NV40 in PS3.0..

So its more a content update to use the overall speed improvments on the new generation.. seeminly..

Devs do most likly use both ATI and Nvidia hardware in development, if they fail to make their games run well on one of them, they will sell less games..
That is why Valve was annoyed at the problems with NV3x, they want everyone to be able to run their game well, and that means extra work for them if the hardware isnt doing that with standard implementations..
 
The questions is: is there any difference between the PS2.0 and PS3.0 paths?

As for who's working on what, yes, I know, but you'll have to wait for the answer.

huh you've been able to run Far Cry with SM3.0?
sorry if I'm being daft, haven't slept for 30-40 hours or so
 
A guess would be that visually they will be the same on NV40 and R420...
Unless there is something they found to cost alot of peformance in PS2.0 but could be done with only a small impact in SM3.0..
what that would be, someone who knows alot about it could prolly give a educated guess on that..

Softer shadowedges maybe?
all trees seem to have realtime volumetric shadows here..
 
I thought it wasn't possible for the moment cos:
- 6800(U) is still recognized as an NV3*
- DX9c still not here (not sure this one is important as SM3.0 is already in DX9)
- Drivers are a bit shabby.

The cards arent out on the market yet, the "SM3.0 mod" isnt either..
but the 1.1 patch did say "added support for PS3.0"..
which wont be exposed without DX9.0c from what Ive heard..
 
Long shaders can be achieved via multipass, branched shaders can be unravelled. Does the SM3.0 patch for Far Cry even include either long shader or branching though?
 
I thought some fonction weren't possible in SM 2.0... I'm wrong it seems.

It would be great if one of the dev on B3D board could do some tester comparing the same effect using SM 2.0 and SM 3.0, to see where it goes.
 
According to the guy from Crytek at the 8600 launch..he said and I will try to quote as much as I can
These new enhancmements can be performed on SM2.0 and Sm3.0 given the power of the hardware

To take that quote in its literal terms. He was saying as long as you have hardware that is powerful enough, you will be able to see these new enhancments wether your are using SM2.0 or Sm3.0. I can see no other way to interpret that, unless someone can enlighten me..

I also take it to understand that current hardware (R3XX/N3X) Is not powerfull enough thus why it was not released earlier.

Might be that somethings might cost alot more peformance to do in PS2.0 then in PS3.0, dunno if there is anything that can be done with only PS3.0 tho...
But in that case, you can almost say "cant be done in PS2.0" even tho it theoreticly can but would cost to much peformance..
 
Maybe its just me, but I think supporting a feature such as SM 3.0 in current games seems a bit premature.. Seems to be a feature that we should be expecting perhaps on next years games (on the cutting edge games that is). I think it's pretty cool to see Crytek adding support for SM 3.0 though. I don't think ATI is going to lose too much sleep over not having SM 3.0 yet though (it really isn't relevant yet IMO). I"m sure the marketing section of Nvidia is really going to be beating the SM 3.0 support drum though! :LOL:

P.S. bbot: you do sound kinda trollish in your post... :?

I'd be willing to bet that R3xx is powerful enough, but NV3x isn't. And given that Far Cry is a WIMTBP game, that's the reason we haven't seen it released earlier.
 
I dunno, even a 9800XT is under hard pressure in Farcry on everthing high..
Add to that weight the fact that it should now render the shadow of every tree as a volumetric realtime shadow (with soft edges even i think) where as earlier those shadows were baked into texture..

Nvidia should promote SM 3.0; it probably cost them quite a few transistors (relative to a non SM 3.0 design) ... transistors they might have used for additional performance ... performance which X800pro and X800XT have already been credited with.
