strange FBO Multisampling behavior

Maybe someone had a similar problem?

(I’m using the java opengl bindings jogl, so the syntax may differ a bit from the c++ implementation)

I’m gettin 16 Samples when quering:
glGetIntegerv(GL.GL_MAX_SAMPLES_EXT, aMaxSamples, 0);

works fine.

My problem is multisampling works only when using 16 samples. Unfortunatly Im loosing a lot of performance using 16 samples. So I tried 2,4,8 for aMaxSamples but always the same result: no multisampling… :frowning:

Im using nvidia 8800 GTX.

Anyone can help?
