Re: [Gegl-developer] Motion blur strange behavior

And so, some tests:

1. OpenCL version of motion-blur:  1.0 s  (GeForce GT 430,   year 2012)
2. CPU version of motion-blur:     >10 s  (Pentium 4 3.0GHz, year 2003)
3. GIMP's old version motion blur: ~2 s (faster, much faster gegl's)

10x times faster. But my CPU significantly slower and older than GPU.

In this case I hope GIMP will keep his fast (even if 8bit-per-color)
filters, sometimes speed is the main thing in image processing. Or
may be GEGL will have faster operations for 8-bit data?

But that's the point of using the GPU! We can have good and awesome
floating-point precision and speed :)

Since your reply landed to my inbox before the original mail, how was
CPU version measured?
