accum + GeForce 5900 FX + linux

Hey Guys!!!

I’m just checking out the accumlation buffer with a 5900 FX ultra…it is sooo slow!!! As far as I thought is that floating point buffers on FX are hardware support. Could it be a driver issue?

Thanks!

Hi,
The accumulation buffer is very slow on all software implementations. The ‘floating point buffers’ are for the fragment programs.
Does anyone know how to perform antialiasing through multiple passes into a pbuffer, in the same way as it’s working with the accumulation buffer, just much faster?

From what I understood, the 9500+ and FX series of cards had hardware accumulation buffer support, though it was limitted to certain operations.

just wait for Detonator 50 for Linux.
Under Windowsin 51.xx& 52.xx it’s exist and fully hardware implemented.

Yes I have the same understanding in that. I get such a frame rate drop even I am rendering only one sample in to the accumulation buffer.

Cool but how long would that take? - Days, weeks, months, …? :slight_smile:

>>Days, weeks, months, …? :slight_smile:
weeks… Looks like it will be in time of presentation of NV38/36.

Now you can check your algorithm under Win32 with existing det50.
