RSX - Best guess at what 300 million trannies are for

Just curious, how hard would it be for MS to push the next DX version towards the exact specification (or is that already set in stone?) of the Xbox360 GPU. Then let their marketing guys go to town with that: "we have the next Dx version GPU, they have last Dx generation GPU... etc."

If they are in the mindset of "being at war" with Sony, wouldn't that be something of a legit (but underhanded) strategy?

 

lol way to compare two completely different games.

 

hahahaha yeah. worst comparison ever, and for a million different reasons.

 

That was a strange comment i must agree.
Of course the CGI looked out of this world... it's CGI!!!

 

As i said, it finally hit me how much more realistic HDR makes things look.

Out of all the X360 games i saw, the ones i think are using HDR were GOW and PGR3 and they were the best looking by far. Obviously not only because of HDR, it must be said.

HDR makes everything non-HDR stuff look totally flat.

I was looking at the new Shadow of the Colossus videos last night and i kept thinking how much better it would look if only it had HDR.

 

I would be very suprised if the R500 does not support FP-blending too - FP-blending is a standard feature for future desktop chips from Ati (and current NVIDIA chips).

 

Thing is I don't think you know the difference between HDR and other forms of lighting like PRT and SH.

 

Your point? We're talking about what we saw so far.

 

Well you're saying GOW and PGR3 uses HDR which isn't really accurate because you don't know what they're really using.

 

Sorry, i just made an assumption.
Point is, whatever they use, they look much more realistic than games using old vanilla 32-bit rendering, like current gen games.

 

Using Spherical Harmonics will give you very nice looking images similar to GI. Same with PRT.

 

Well that's good.
It will be interesting to see how different lighting systems will look in the new games.

David Kirk (nVIDIA) said:

1)RSX can use XDR-RAM(256MB) as VRAM too.

2)7 SPEs and RSX can work togehter as total GPU. SPE as vertex shader
,post processing a rendering reslut from RSX etc...


Sorry, my english is poor. I expect Mr. one will translate this article.

 

Where is ONE when you need him? HEELLLLLLLP

 

PRT = What people call Spherical Harmonics.
The most common method used for Precomputed Radiance Transfer is to render light maps using Spherical Harmonics (SHLM).
The problem with this tech is the better the SHLM are and the bigger the memory footprint is. Without talking about the lighting "incoherences" (For a lack of a better word) that happen here and there.

Rare's Xbox Conker L&R uses PRT for the main character, it looks very good.

BTW, about the HDR/MDR, what's the precision of the R500 framebuffer, 64bits or 128bits?

 

The first point was already know; Sony offered the figures themselves for the read/write bandwidth between RSX and the XDR-DRAM. The second point isn't too surprising if one thinks about displacement mapping and vertex textures.

 

they don't talk about AA, they don't talk about AA... bad sign

 

yep. noticed that.
