ACCUMULATION BUFFER & GEFORCE 2 GTS
Author
I have recently bought the creative geforce 2 gts and i have downloaded the lastest drivers.
Its really fast but when i use accumulation buffer its very slow between the render function. I know my code its correctly and the render function its fast but the pixel transfer it stoo slow.
I want to know if the geforce 2 have this problem or if all graphics cards have this problem.
Tnx in advance.

I don''t think that the GeForce has a hardware accumulation buffer - in fact you''d be hard pressed to find a consumer card that does have one.
Most drivers probably revert to software mode when you try to use it...

well, it might have one, since it has fsaa. i dont know what supersampling method it use, but if it renders a 800*600 resolution, to the acu'' buffer as a 1600*1200 image, sample it down back to 800*600, to the frame buffer, and gets an anti-alised image, it probably has a hardware acu'' buffer.
but maybe not.
but maybe not.
You can''t.
The Geforce uses supersampling to do anti aliasing. That''s all in the drivers and doesn''t use anything like an accumulation buffer.

But i dont do antialiasing but some efects like motion blur.
If i cant do it with accumulation buffer how can i do it?????
Tnx
