Forums - Microsoft - So could the X1's secret sauce be "Voxel" Cone Ray Tracing?

So, any predictions for next week's secret sauce anyone?


Don't what or if xb1 has a secret sauce. Sony's secret sauce is hype with a side over promise and a bit of under delivering.

PS2 = Toy Story graphics 

PS3 = Most advanced system (on paper)

Hands down Naughty Dog had the best looking games this gen, everything else was on par with the 360. Good developers, except no substitute.

Why do people post as if they are forced to browse to the MS section and read these threads? I feel sorry for you guys, being forced to read threads and post in threads you don't care about :(

Also, Xbone will be the KFC of the console world. 11 secret sauces.


They can't allow there fantasies to be challenged. Reminds me of U.S. politics, it's all about pre-conceived notions as aposed to results.

people moaning at OP fear the One has some extra tricks up its sleeve and is insanely futureproof and probably are just mad at that? cant see a reason this moaning happening otherwise


Kind of sad really, they arn't happy with there console of choice. So they must come to the opponents side and whine about them talking about possibilities.

There is only one hardware chip in a retail product that supports it DirectX11_1 and Tier 2 - PTR.  One that just coincidentally shares similar unit counts to the GPU in Xbox One.  That is the Bonaire-based AMD GPU.

Why are bringing up shit time and again? And what the hell has "unit count" to do with hardware features?

In every slide Sony has shown about the gpu they mark it as having DirectX11.2 compatible features (they even label it as DirectX11.2+)

A DX11_0 HD6000 with a driver update from AMD will be DX11.2 compatible.   They don't support the DX11_1 feature level. 

To put this simply.  DirextX 11.2 is not the same as the DirectX 11_1 feature level.  The Tahiti and Pitcairn cards are DirectX 11_0 feature level. 

XD, you are so clueless its not even funny. The update applies to all GCN GPU's NOT on AMD's older architecures that include the radeon HD6000 and under. 

BTW Tahiti and Pitcairn both support DX 11.1 feature sets.

Thanks for the interesting read on voxel cone tracing, too bad it's spoiled by rotten sauce arguments.

Here are some videos of the current state of voxel cone tracing:

its the same couple people who make the same threads again and again, Then a different group, comes in and says why its technically not possible. Then a 3rd group comes in and goes off about the second group for harassing the first group.

atleast its not Misterx's latest rumor that since the Xbox uses more watts, it must be more powerful.



I am Torgo, I take care of the place while the master is away.

"Hes the clown that makes the dark side fun.. Torgo!"

Ha.. i won my bet, but i wasnt around to gloat because im on a better forum!  See ya guys on Viz

Going to drop a bombshell.

Not all HD7000 series GPUs are the same.

Some AMD HD7000 series GPUs only support the DirectX 11_0 feature level, yet they are or will be DirectX 11.2 compatible with a driver update. Only the Xbox One's GPU is DirectX 11_1 feature level compatible. The "Tahiti"/"Pitcairn" line of AMD GPUs are first generation GCN, which is what the PS4's GPU is based on. The Xbox One's GPU is based on the "Bonaire" GPUs.

Why does this matter, it's only DirectX right?

No.

DirectX 11_0 level GPUs only support Tier 1 - Tiled Resources. DirectX 11_1 level GPUs support Tier 2 - Tiled Resources.

Yes, the PS4 will have similar capabilities as the Xbox One, even the Voxel Cone Ray Tracing. The difference is that the Xbox One's GPU feature full hardware (Tier 2) where as the PS4's is software based (Tier 1).

As mentioned in the original post, Voxel Cone Ray Tracing uses Tiled Resources. Both the Xbox One and PS4 are capable of supporting Voxel Cone Ray Tracing, but the Xbox One's implementation is hardware based. Meaning faster.

That is the secret sauce.

LOLOL are you clueless ?

You realize that tiled resources and PRT's are the same thing right ? That also means that the PS4 will support tiled rendering via the opengl extension AMD_sparse_texture.

How do you know that the xbone is based on the bonaire ? if anything its more similar to cape verde in performance

And that last part that is bolded is wack lol, I think you don't know what your talking about.

Yes, I do know they are the same thing. 

The differences it that Tier 1 support is software based, Tier 2 is hardware based.  The resource mappings are done in code on Tier 1, they're done by the GPU in Tier 2.

This is me sitting while I laugh at you.

There are no Tier's of PRT's. Deal with it. AMD has added hardware implementations on ALL GCN GPU. It doesn't just apply to bonaire but to every AMD radeon hd 7000 series that doesn't use a 40nm process node. Your trying to hard to be like ethomaz lol.

Edit: It's over I caught you red handed for being a fake in the knowledge of the hardware world.

BTW Tier doesn't stand for level's of hierarchy but rather it stand for a set of features that's part of DX 11.2.

Edit: It sounds like you don't understand jack about coding. Your a fraud as said before.

Here's a question for you all who believe there is some secret sauce that makes the One as powerful or MORE powerful than the PS4: Why did MS give BOTH the CPU and GPU a boost as a direct response to PS4's specs?


It's just an optimization, if the hardware can stably do it, why not? Also, why would MS's "direct respnse" be something that doesn't come close to evening up the paper specs? 

Because it's the best they can do with the limited time they have...

It's clearly a response. They don't want the gap to be as big as it is.

It's too late that edge article detailed the whole situation and others can't accept it.

..some fibberish..

Seriously, you shouldn't discuss technical stuff when you have no idea of what the jargon means. Just for your information: DX11.2 is a superset of DX11.1. In other words: Everything DX11.1 does, DX11.2 cab do just as well (actually some thing can be done better). If Sony writes on its slides that the gpu is equivalent to a DX11.2 device, then it can (in principle) do what the XBox One DX11.2 device does. This is all we need to know at this stage. And no, ray tracing is not something any of the consoles is capable of doing (well, maybe 2-3 fps are possible).

Like I said before, ignore him, he appears to be a stain in the ones with knowledge about hardware.
