Re: Good news for the driver stack

If I understood correctly what he'll be doing (porting the OpenGL stack to run on the ARM core instead of the VPU), isn't that going to slow things down?

You can't really do anything about it. Only Valve has the source code, so only they can port it to the Pi.

Re: OpenGL and OpenBox

It's not a window manager problem. The Pi doesn't support OpenGL, so you'll have to modify your application to use OpenGL ES instead.

It states "No hardware accleration detected." but I thought there is some hwa on the Pi ... There is, but it's not what your game supports. Your game uses OpenGL while the Pi has hardware acceleration for OpenGL ES. OpenGL is initialized with GLX (on systems with an X server like desktop Linux) whi...

As I said, Quake 3 was released in 1999. Quake 1 was in 1996 and Quake 2 in 1997, that's why I said earlier that you were probably mistaken and thinking about an older Quake game.

Re: Quake 3 Arena at 60 FPS

Now you're just trolling. The only beta version of Quake 3 was the one called q3test and was only released online, never as a paid boxed product. And it came out in 1999, only a few months before the release version.

Re: Quake 3 Arena at 60 FPS

I still think you're confusing Quake 3 with an older game. Quake 3 came out at the end of 1999. It's minimum system requirements according to the box I have in front of me were a Pentium MMX at 233 Mhz and 64 MB of RAM. At the time it came I had a Celeron running at 500 Mhz with 128 MB of RAM and a ...

Re: Quake 3 Arena at 60 FPS

You weren't running Quake 3 at 1080p with 4x MSAA (the default settings on the Pi) back then and you certainly weren't getting 60 FPS with those specs. I doubt the game would even run on that machine, perhaps you are thinking of an older game like Quake World?

Re: Raspberry vs. Xbox 1 or other 600mhz pc

If by processor you mean CPU, the Xbox should be more powerful than the Pi, at least 2 or 3 times more given it has an out-of-order CPU with SIMD, more cache and a better memory controller. The Pi has a more modern GPU and more RAM though, so it's not that easy to compare them.

Re: DOS Emulator / Limiting the CPU?

Having the source code of the driver won't change anything to the situation. I don't really see how DOSBox can make any meaningful use of the GPU, aside from applying some filters to the final image once it's been generated on the CPU.

In any case, I think that tapping the GPU is the key to reasonable dosbox performance, and from what I understood, progress in that has been held up because Broadcom did not initially release their source code, which they just have, for the GPU. That's not correct. You don't need the driver's sourc...
