Yes, we saw this message with 2 monitors connected to a 256MB graphics
card (on a project which had begun on a 512MB card) (DVCPro HD
1080i50 project). Bought a new card and the message went away.

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.
