Multithreaded resource loading

[Andru]

To bad that this approach requires a context switch

I switch context only one time - for creating second context. After that all threads working without switching and waiting

Here the MacOS X version of demo compiled under MacOS X 10.6.3

Downloaded! I'll get back to you once I have time to run it after work. I'm running 10.6.4 (Snow Leopard) so it should be compatible I'm sure.

I tried your demo and it works. I assume that the music stopping when switching to different windows is intentional?

My PC is:
OS: Windows 7 Ultimate
CPU: Athlon II X2 240
GPU: Sapphire Radeon HD4850 512MB

Yes, and it must continue playing after returning the focus to demo.

It continues playing.

I also tried it on another PC, at my work.
OS: Windows XP Professional SP3
CPU: Intel Pentium Dual E2200
GPU: Intel 82945G (i945G) integrated

It worked on that PC too. If it works on the Intel card with shoddy OpenGL drivers, it should work anywhere.

Well I gat back from work and gave it a run. For the most part it runs just fine, graphics display and the sound clip plays too without any popup errors. However the one bug I found was that most of the faces were showing a block of glitchy and random static instead of their respective sprite. Here is a couple of screenies to show basically what it was doing.

Go ahead and send me an update or tweaked version if you like. I can be your 'real test run' on the current iMacs if you like.

My system specs are:

CPU: Intel Core i7 (Quad Core)
GPU: ATI Radeon HD 4850
Screen Res: 2560 x 1440 (27" screen)
RAM: 4GB DDR3
OS: Mac OS X 10.6.4

You need to switch the context. Otherwise your rendering commands will be send to the wrong threads if you want to handle drawing onscreen.

Why you so sure? OpenGL has a rule - "one thread - one context", so situation "will be send to the wrong threads" never will happen, and my demo works as you can see(only Windows version has a problem and it will be fixed the same way as MacOS X demo)

Can you test this new demo for Windows, please?
