Is there something wrong with this new/old update? I'm trying to render a scene created with the previous patch ( which happens to be a newer one, but we reverted back to 277255 short after I made the scene), and it rendered in 3h30 at 1600x900. Now I made some tweakings, and after 10h, I only have 6% rendered. The tweaking is not much, changed a little some materials, but didn't make any changes that would suggest such terrible render time. Oh, and I'm rendering to disk, btw! Have anyone encountered this?

Try loading a sample scene from the CD that you've rendered before just to see if rendering time has changed drastically.

Never rendered a scene from the CD. I've tried rendering the same scene to screen, and it took a reasonable amount of time. Maybe this was THE update that had a buggy rendering to disk, since I remember there was such a problem with one of the updates.
