From his blog: RSXGL Working and Usable

Hi everyone!

When the PS3 homebrew scene started, a lot of people were complaining that it wasn’t possible to write 3D games for the PS3 because of its lack of OpenGL library.

Almost a year ago, Alex Betts thought he would tackle this problem and he started working on RSXGL... an implementation of the OpenGL 3.1 specification written from scratch targeting the PS3′s RSX.

Anyone in their right mind would say that it’s impossible, that it’s too much work, but Alex spent the last year working on it, alone, until it became usable. You can read some news about it here.

For some reason though, no one used it to build their own apps. Maybe the status of the project was scaring them, it was said to be incomplete, there was no GLSL support, etc...

I am writing today to tell you that RSXGL is perfectly usable! It supports online GLSL compilation, as well as any feature you might want. As proof, I have written a new hardware accelerated engine for the EFL using RSXGL and it worked great!

Alex and I spent a lot of time testing and fixing all the issues that were in RSXGL that were made visible by the EFL’s GL engine and I am happy to say that it’s working now. Expedite is able to run most of its tests at 50 to 60 fps on 1080p resolution (instead of the average of 5 to 10 fps it had on 720p before).

You can see performance tests right here (Running some tests from expedite) :

Please give RSXGL a try. Also, you can get the latest EFL version from my repository, which includes the gl engine for PS3. Now, any EFL application will be automatically hardware accelerated thanks to RSXGL. I hope we can see some new games (or old GL games being ported) soon!

Enjoy!

yeah i agree i think the ps4 should be released by mid 2012 myself.what would be nice is if you can get a plug in upgrade/adapter for ps3 to make it more powerful.. but i'm not sure if its possible.. i remember seeing something about it being patented by sony here 3 or 4 months ago.. would be good as i have a few 60gig consoles to sell.. LOL

i agree totally also mate but last time i said ps3 was outdated etc i got flamed at.. LOL

Well elser1, you don't need to be an expert to know that it is obsolete. The fact is by the time the PS3 was released it was already outdone, it wasn't a full 7800 GTX, it was a crippled version. Supposedly the original PS3 design had no GPU, it used two Cells instead, I don't know if that was just a rumour or a fact. The RSX is outpowered by several generations... the 7000 generation itself which it's a part of, 8000, 9000, GTX 200, GTX 400, GTX 500 and soon GTX 600. Before the PS4 is released there will likely be a GTX 700 series.

For what it's worth the 8000 and 9000 series are the exact same technology and the GTX 400 and 500 series are almost identical in architecture. But the fact of the matter is that it was too weak right off the bat which is ridiculous for something that is supposedly designed to last many years.

At this point the RSX is so old and alien compared to modern GPUs that it's not comparable at all, it comes nowhere near even scratching the surface of how powerful modern ones are. Just look at how hard the engineering team of RAGE has to work and struggle to make RAGE pretty much the only game out there on the PS3 which has both nice graphics and runs at 60 frames a second. It's incredible stress on the developers being limited so much.

Anyway, that's why I believe it's not possible for Sony to delay the PS4 until 2016 as they keep saying they'll do. At latest it will have to be 2013, which in my opinion is already years late.

i'm no expert but my friends say the ps3 is obsolete and outdated. i see there pc game graphics and i see why they say that. the 7800 nvidia was good in its day but even my old pc has better graphics card than that... but i still like my ps3 and thanks for this info..
