Public bug reported:
Binary package hint: blender
Rendering on 64-bit ubuntu is much faster than on 32-bit xp (up to
40%). However, raytracing in ubuntu is really slow, so slow it can be
considered as a bug, because windows can render at multiple speed
compared to ubuntu when that option is enabled.
Testing:
- Render a scene without ray tracing and compare the rendering times with xp
and ubuntu and notice how much faster the latter is.
- Re-render but now ray tracing enabled. Make sure that most large objects on
your scene are reflective and transparent.
Both operating systems are now rendering slower than without ray tracing
but ubuntu almost stucks.
** Affects: blender (Ubuntu)
Importance: Undecided

Ray tracing too slow (not joking)
