Nice demo.
I also noticed the texture thingy, but I'm not sure the "right" solution is to flip the image using paint. I rather say you should flip the texture coord.

The Radeon 8500 has the ATI_fragment_shader demo, and even if you can do lots of effects with it, it's quite far to fragment shaders. I'm not sure parallax would be possible with ATI_fs.

Apart from that I love the loading screen. Very neat !

@vincoof:
thank you :D
i've just flipped tex coords and now works perfectly :)
the loading screen is the symbol of Ouroboros, the cycle of life ^__^'

On my Geforce Fx 5700 256 i have ~60 fps... how's your framerate?

Aw... I didn't know it was Ouroboros. Thanks !

With a GeForceFX 5200 Ultra I get the following :
ASM shader : 54 fps
Cg shader : 65 fps

Note that your app syncs to vertical refresh by default. That's why you get constant 60Hz. You should disable vsync in the driver in order to get more relevant framerates.

And BTW please try to increase your monitor refresh rate. 60 Hz is pretty low ! Don't hesitate to lower the screen resolution if needed, your eyes will thank you :P

This is the error i get:
Log Entry: ERROR: Not enough texture units!
my fault?

ATI extensions *not* supported?? *lol*
I think you need to be more specific about
exactly what extension(s) lacks support.

the logger code is a bit *old* :P
