Does this happen due to frame buffer? Strange. Its possible, I of course dont compile these frame buffer things in as I run X . > CONFIG_FB_VESA=y > Soooo, I renamed agpgart and played around a bit.

Yes, I too am getting similar readings at 24bpp at 1024*768. Defninitely without doubt the 2.4 series of kernels is faster for the nvidia drivers than the 2.6. I notice that when you enable preemption the 3d performance goes down. ACPI of course slows down everything horribly, ACPI in linux (even in the 2.6) is just not on yet. For example try ripping a DVD to XVID/DIVX using mencoder and note the FPS you get, now try enabling/disabling ACPI and see the drastic improvement in frames processed per second.
