RSXGL: OpenGL 3.1 Support For The PlayStation 3

[const]

... but he's really just invented a non-round wheel

in my native language there is saying that i will try to translate and i hope keep its meaning "even the God is speechless when the numbers are talking". so, "non-round" or not, the numbers in this case make enough of a statement about the work:

* without RSXGL: http://dl.dropbox.com/u/22642664/expedite_psl1ght.log

* with RSXGL: http://dl.dropbox.com/u/22642664/expedite_rsxgl.log

and before that the situation with PS3 in that area was pathetic. so, i don't get the criticism - it would be appropriate only in case someone did better job for the graphics support in PS3.

The point Betts made is that he started out with a legacy free API. Some new features of OpenGL 3.x were supported by older graphics hardware and were therefore released as OpenGL 2.x extensions as well. Betts says that he hasn't implemented full support for all OpenGL 3.1 features (which as you say isn't possible) but he also hasn't implemented most OpenGL 2.x functionality that isn't in GL3 and is probably not available in the RSX anyway (mostly FFP support).

So he's not implementing GL3.1 at all then. You can't leave half it out and call it GL3.1. How would any application know what to use? you'd have to write app specifically for it. Why not just mesa to implement GL2.1 + extensions, seems like it would match the hw and be a lot more useful, the nvfs driver already exists and could be reused for many parts.

Like people can do what they like in their own time, but he's really just invented a non-round wheel.

Nvidia itself puts OpenGL 3.x support since 8800 series (DX 10 level support) and this freak claimed that he can do the same with a 7800 GTX.

No, I don't buy this.

this freak

Alexander Betts is not a "freak", but apparently quite talented developer and he did excellent job - actually performance bump without and with his work is really freaking enormous:

* without RSXGL: http://dl.dropbox.com/u/22642664/expedite_psl1ght.log

* with RSXGL: http://dl.dropbox.com/u/22642664/expedite_rsxgl.log

you maybe not buying it and if it's OpenGL 2.x or OpenGL 3.x doesn't really matter to me considering the performance improvement his work brought as per above numbers. also, no one knows what are the specifications of the "RSX" chip inside PS3 - it's just rumored that it's close to "7800 GTX", but no one except Sony and nVidia really know. in any case, what did Alexander Betts works and gives great performance - what better prove than that. last, but not least - it could be CellBE provides additional computational power to the "RSX" chip for what's necessary additionally to OpenGL 2.x in order to have OpenGL 3.x. so, do you "DebianLinuxero" happen to know those things for sure and based on that make statements?

so, thank you Alexander, keep going and don't be discouraged by incompetent Linux script-kiddies, calling you "freak".

That developer lie or is freaking

There was this disapointment tha PS3 "next slim" is not hardware improvement...

But now we have solution for it Homebrew to boot

GJ!

Phoronix: RSXGL: OpenGL 3.1 Support For The PlayStation 3

According to a developer that began working on a PlayStation 3 graphics driver, which he's calling RSXGL, he reportedly got OpenGL 3.1 working from this Sony gaming console...
