Sure it could use a pagefile. It's already running a virtual memory system, it's just not backed by a pagefile. Once you have virtualized memory, adding a pagefile is straight forward. Will Sony add it? I doubt it. It would mean that as a developer you could care a little less about memory...

I'd love to see it.

It's difficult/expensive to implement a horizontal add, which is required for the 1 cycle (throughput) dp instruction. Usually, we'd just transpose our vectors/matrices and do 4 dp's in '4' cycles, which is essentially the same. The XeCPU would have the advantage if you need to do less than 4...

Not in reality, because 4xAA will take up more edram, so you have to draw more tiles. Folks, I don't know how many times I have to say this - 720p + 2xAA DOES NOT FIT INTO 10mb of edram. Period. End of story. The scene has to be tiled , ie - executed multiple times. This is required, as the...

All that edram bandwidth is only helpful if you're actually going to use it. It will only be an advantage on lots of alpha belnded polygons and short shaders. If the shader is of any decent length, you won't ever use that much bandwidth. Recall that the X360 GPU's edram is also a...

You kidding? Carmack's engines are always more optimized and have the new tech sooner. (ie, Doom3 is on Xbox and has the nice shading, whereas UT on Xbox looks like ass). UE3 runs slooooow...even on a top end modern system.

Yeah and that's the problem. All UE3 games have a similar look/feel.

The PS3 has been in development for 4 years, at least.

Take note MS - this is what a launch should be like! No Frodo, No Ring of Light, No hip-hop/rock with teenie boppers around, no PDZ type nonesense. Other notes... NVidia GPU: I think it's pretty easy to tell that it was totally bolted on last minute. I think Sony wanted to do their own GPU...

The only thing I'm not sure of is the MSAA compression. Haven't looked into it. The rest is correct. You don't need access to the post-transform vertex cache if you reissue the entire scene. The game has to redraw, but there's a some hardware support to help out. I'm 100% on this, I'm sure...

Well, I'm tellin' ya - 32bit min for rendering surfaces, HyperZ is on edram, there's no compression afaict, and developers will have to tile their scenes to make hidef rendering possible with AA.. and no you don't go from 256gb to 22gb. You split your scene vertically/horizontally.. render half...

Can't get rid of stencil or alpha. 32 bit render target is the minimum. Not so sure about compression. HyperZ is in addition to a 32bit z/stencil-buffer. Hidef + AA + HDR is possible even without enough edram ram.

720p is a requirement. When you work out the numbers, you'll find that you can't do 2xAA @ 720p with 10mb edram. Doh! Well, that's not totally true.. you can, and they sorta expect you to, but it's a PITA.

Yup. Same thing at GDC. All the Microsoft reps were saying how the next-gen xbox is so awesome, will revolutionaize the gaming industry, and what not. They had massive "short guy" syndrome, trying to get your attention with the "look at me!" attitude. Allard was even bashing Sony during his...

Nope. UE3 is a DOG.
