Hi Brad,
for GPU rendering, Final Cut needs to create a few full-sized textures
for you (at least one for input and one for output). A float texture
is four times as big as an 8-bit texture, so with large frame sizes
and older graphics cards, it's possible for you to not have enough
VRAM to create the textures with float processing.
Compounding the problem is the fact that if you have two monitors
attached to your graphics card, we will cut the amount of available
VRAM in half, in order to work around some GL driver issues. You
don't say what your sequence format is, or if you have two monitors
attached to the card, but my guess is that you are working with a 2K
sequence and have two monitors attached.

I'm getting an error message with my plug-ins from Final Cut saying
that the effect failed to render, because the hardware cannot render
at the requested size and depth. My sequence settings video
processing is set to "Render all YUV material in high-precision
YUV". My plug-in is supporting R4FL, as well as, all the other
rendering formats. I'm rendering in hardware only in the plug-in.
If I switch back to, "Render in 8-bit YUV" the message goes away.
Why is this message happening? I'm using a MacPro with an ATI
Radeon HD 2600. I'm performing the rendering in Core Image. Why is
Final Cut giving me this error message? The graphics card should be
able to support higher than 8 bit rendering, right? I'm using the
latest version of FCP, 6.05.
