why do all pixelformats which are returned by DescribePixelFormat have 64 bits accumulation buffer?
GeForce 2 GTS
NOTE: I mention the ones whose

Well i know that the accel buffer is not supported in hardware on any consumer card but i do know that the accum buffer requires a 64bit depth because it needs all of that precision to work. There was a post a while back about this, Matt from nvidia was talking about that.

I don't see how the presence of an accumulation buffer is harmful? (And yes, we can lazily allocate it, so unless you use it, it costs you nothing.)
