Hi everybody, I run the techdemo, first I select DirectX to render, and after that I select OpenGL. The color in the scene are very different each time. Do anybody have the situation like me?

Could you explain 'very different'? Best would be to post a screenshot.

Colors are similar with me ( your problem may come from your drivers settings, for example with my NVidia Drivers, i can set luminance, chroma... for direct3D)

About differences between DirectX and OpenGl,
Button's font are different :

When i use OpenGL with GUI Button, I can HARDLY read what's written on buttons, but the gui::IGUIFont objects a perfectly readable.

Here is a screenshot ; The word "Quitter" is written on the GUI button, but it's hardly readable :

On the screenshot, all default settings are used for the font.

That problem does not appear when using Direct3D

I heard of some people which had the same problem. On my hardware, this problem doesnt occur. But I'll try to find the bug.

I can also report that the OGL default font looks bad on my 2 machines:

win98, onboard vid
win2k, voodoo3

I've tested under Linux, (same code as the one on which I've done the screenshot) :

There are no problems, button's font is perfectly readable.
