Im starting to be disappointed that i recently bought nvidia, and your ignorance and saying that nvidia drivers are perfect and thats only kwin issue is such an absurdish statement.
KWin doesn't use OpenGL 3.0. Mesa doesn't support OpenGL 3.0 yet. There are plans to move KWin compositing to OpenGL 3.0 for KDE 4.7, but that's in the future. Nvidia's drivers share most of their code base with the Windows driver. OpenGL 3 and 4 work fine with Nvidia's linux drivers.
