As far as I can tell, pI isn’t running on software rendering. Hardware acceleration is turned on. In regards to the accumulation buffer, the OpenGL info window has this: “Accumulation Buffer RGBA: 0-0-0-0.”

[Elvis Deane] “Is the button for High Quality motion blur just unclickable? You can try to open the project in pIllusionRender, and see if you can select HQ moblur in there.”

Yes, the HQ option is unclickable. I did try pIRender, but the HQ option is also unclickable.

[Alan Lorence] “What do you have the motion blur “extra frames” setting to something reasonable like “3”. If you have it set too high, the “artifact” problem will be worse.”

Initially, I did have the frame amount set to 10 and then I lowered it back to its default setting of 3 to improve the quality. Although the artifacting is minimized it is still noticeable, even when I have the frame setting as low as 1.

[Alan Lorence] “What video card do you have?”

ATI Radeon 9800 XT w/ 256MB VRAM.

[Alan Lorence] “Windows or Mac?”

I have the Windows XP OS (unfortunately).

[Alan Lorence] “HQ motion blur uses the OpenGL accumulation buffer which is not supported by all video cards. It may be that you need to update your video drivers (if Windows) or that your hardware just does not support it.”

I went ahead and updated my card with the latest drivers (Catalyst 5.12 for Windows XP from the ATI website) and I still get the same results as before. It would appear that my particular video card simply doesn’t support that OpenGL feature you mentioned, though I have been thinking about overhauling my machine for a while now. Can any of you recommend a decent video card that’s capable of exploiting all of the graphical features of PI?
