View Full Version : "Hidden" pixel formats with nv30 emulation

03-20-2003, 10:14 AM

When running NV Pixel Format with nv30 emulation on it reports 102 pdfs. Every format is marked to support opengl.

If I query the driver using the WGL_ARB_pixel_format extension with no attributes it also reports 102 pfds.

But, if I specify the WGL_SUPPORT_OPENGL_ARB attribute for example, the number of pdfs drops to 27. Similar if I want a 128(96) bit color buffer with pbuffer support it returns 0! Anyone that recognizes this? Is the emulation bypassed when specifying attributes to wglChoosePixelFormatARB?

I have a gf2 with 43.00 drivers.
