0.6 is slow

maybe not slow but version 0.5 was super smooth in fullscreen mode with Direct3D 8, 9 or OpenGL.
Now in version 0.6 the framerate isn't synchronized with the screen refresh rate anymore and the graphics flicker and tear.

Ah, thats bad.. I'll add a vsync option in the next version.

I have same problem (graphics flicker). In previous version 0.5, Irrlicht had presentation interval ONE for DirectX (no problems here), but in version 0.6 presentation interval is IMMEDIATE. I think it's better to use presentation interval DEFAULT in next release.

I was under the impression that VSync saved you memory on the vid card by rendering less frames rather than speed, although I could have heard wrong.

Not really. Memory allocation <-> back buffers. More back buffers you have, more speed you can get and more memory is needed.

Presentation interval IMMEDIATE should be never used without back buffers.
