Xenos and its special features: Educated expectations needed READ: post #126!

I am no expert but more powerfull really depends on what we are talking about. From everything I have read here xenos is monster at VS and leaves the RSX behind. Looking at sony's edge tools it seems to back that up with sony using up to 2/7 of the cell or 2 spu to cull triangles to help it catch xenos. If I am wrong I would love to be correct on that.

Have you read the following by ShootTheMonkey?

For all you might say about the dynamic allocation of vertex pipes, you end up limited by a lot more external things than anything internal to the GPU. Also, no matter what, on major passes, you're going to end up spending more effort on pixels anyway, and RSX has a moderate advantage over Xenos in that area. All the same, getting a billion triangles per second to the GPU in the first place is basically impossible. It doesn't matter how much power the GPU has to work with them because it can't get to that point. In general, the challenge in getting 100-150 million tris per second moved through the pipe is hard enough whether you're on PS3 or 360, and it's not the GPU itself that's the problem.
 
Interesting Point. In Theory, the Xenos is more poweful than the RSX. But in practise? In another (locked) thread, dantruon posted the following:

What do you think of it?

i must clarified something here, when i said that the RSX whipped the Xenos ass i did not imply by itself the RSX is better than Xenos in a practical situation, what i really meant to say was that the RSX +CEll in practice is a better combination than the Xenos +Xenon combination, and i think there is no denying the fact that RSX by itself is like a clawless cat but when it combined with Cell, it is a fearless tiger.

sorry about the awful analogy.

from what i gathered so far on many forums including this one i come to the conclusion that the Xenos beat the RSX hands down in theory but in practice the RSX whipped the Xenos's ass painfully.

Rofl.

What your saying doesn't make any sense.

First you make up some crazed GPU theory, and now your just drawing straws because you got to much negative rep.

When you said that the RSX whipped the Xenos ass, you did imply that the RSX>Xenos in a practical situation, there is no way in hell you meant something else, you mentioned specific PS3\X360 parts.

Basically, what your trying to say now, that in practice you think the PS3 is more powerful than the X360.

Its also fun, that you say "in a practical situation", because frankly, in practice, RIGHT now, the X360 is at least as good as the PS3 graphically (Gears anyone?)
Now, im not saying the X360 is better, but saying in practice, would imply the results we see right now in games...

Now, i believe that in theory, the PS3 is more powerful, and that eventually we will see results of this (aspecially in physics, not so much in graphics), right now, in practice, there isn't really anything that would imply one is better than the other.

I also believe, that Xenos combined with the Cell, would be a better design choice, altho it would mean the console would be even harder to work with
 
The Xenos, is imo, not only on par with the RSX, its much more sophisticated than the RSX.

I do belive, RSX will have a BIG problem doing 4x AA @60fps, because its to low on bandwidth. (Forza 2, the first game that uses tiling on the X360, will do just this)

This is kind of ironic in light of the new demo. No free 4x AA for now I guess.

Well, that basically relates to the same thing that rounin quoted. It's free at the GPU in theory, with only the minor cost of having to re-process a small percentage of the triangles. The problem with the "free AA" statement is that it leaves software out of the equation. If the CPU has to shuffle data (which is something that is never a raw power issue), it can't be free anyway. If you've got the time to spare, it'll probably *look* free of course, but that's a case-by-case basis -- nothing you can say as being a general rule.

what i really meant to say was that the RSX +CEll in practice is a better combination than the Xenos +Xenon combination, and i think there is no denying the fact that RSX by itself is like a clawless cat but when it combined with Cell, it is a fearless tiger.
What makes me wonder is that you mentioned having gotten that impression from several boards including B3D. And I'm not sure what threads you were looking at where anybody said that the RSX+Cell combination "whips Xenos ass" let alone whipping it painfully. That too, whatever the combo of RSX+Cell does, you can theoretically do a lot of the same on Xenon, but it remains to be seen what sort of benefit that will really have on the 360 since you aren't quite as limited. I don't see backface culling in software on Xenon being that big a deal. Software skinning could be, not just because you move less data, but because you have a little more freedom to do more interesting things when you do it in software. Interesting things on the GPU don't come cheap.
 
The Forza 2 demo looks to not have any AA in actual gameplay. There is a lot of aliasing around. When the race is over the framerate seems to drop by about 30-50% (guessing) and there is some AA.

One thing I've noticed is that there is no AF. And, if you wander off the road, I've seen some horribly unfiltered mip map levels right in my face, right off the bumper. Even my non-techie friends noticed this and said it looked really bad.

Are you sure? Xboxyde had a video for forza and it was pretty apparent that there was AF...
 
Also Forza 2 has AAx2 during gameplay (most of the time at least). There are very distracting jaggies on cars though, but I believe this is due to shader aliasing and multisampling doesn't remove that.

There's AF in forza 2, both gameplay and replay. In gameplay, the MSAA is dynamic, scaling between 0x, 2x and 4x to preserve the 60fps.

In replay, the framerate drops to 30fps and it gains motion blur and 4x MSAA.
 
che stated as of 2 weeks ago it was a flat 2xAA in game 4x in replay... perhaps they are still cheating occasionally though with the AA
Che has lied so many times about the graphics that he really shouldn't be considered a useful source of information.
 
Well, when you wander off the road, it looks like they decided that even bilinear mip map filtering was unnecessary! I mean, the filtering is so icky that the worst tricks in PC history pale in comparison. :)

You can tell there is AA after the race, because the mountains in the background have a nice anti aliased edge. During play, that same edge is definitely aliased. Perhaps the TV is causing aliasing (a 50" 720p plasma)? It doesn't look quite like 2X AA to me.

FYI, I'm not trying to say the game looks bad. It looks great for the most part, IMO. I do wish they'd had the constant 4X AA and better filtering. 360 was purported to be able to handle 4X AA at 95% performance, remember?

been mistaken occasionally, most likely
Internet: Is that in-game graphics?
Che: Yes, I just paused and panned the camera around.

Translation: No, it's photo-mode.
Interpretation: Lie.

Always-on 4xAA, bub.
"Building it from the inside out, gameplay first, graphics later", bub, to damage-control the disgust of the press when presented with the graphics, while in reality they have been working exclusively on the fuckin' photo-mode and the gameplay graphics did not improve one iota.

Wow, and there goes every ounce of your credibility out the window. DISGUST? Have you played Forza?? Ya, it has some jaggies but the game still looks really nice. Talk about spreading a load of bullshit :oops: If you're going to make completely untrue statements like that, you need to take a look in the mirror.

graphics did not improve one iota.

#1. The final game has not even been released. So, what the hell are you basing this statement on?

#2. And the differences in replay-mode and ingame are very small, if you play the demo for yourself you'll see this. It has a little extra AA, some motion blur, and some depth of field. That's it. It makes for a subtly nicer looking scene, but certainly not a large difference by any stretch.

My limited time with the demo I'd say the graphics aren't the best I've seen, but it is 60fps which is important for a racing game and it is simulating a ton so when taken into consideration, I'd say the graphics hold their own.

Regarding the texture filtering when off road, I honestly did not see a problem with the grass/dirt texture at all and thought it looked great. The 3d grass blends in well at high speed and looks ten times better than a simple screenshot would imply. The car models look good enough but the lighting is a mixed bag. At times it looks perfect, at other times (within the same race) it looks horrible. The trackside graphics looked much better in motion than the screens would lead one to believe.

Overall, I'd say for anyone that was/is interested in the race simulator genre, the game is great. Certainly worth a free download to check out for yourself. ;)

have you played the GTHD demo? if so, would you be able to compare them and suggest which one is overall better?
