render problem

not sure where to put this but since Ive upgraded to latest version the rendering runs ‘dog’ slow.

Whats changed to make the same level of render slower in the new version?

1st to reply oh yah!

Are you sure that it’s blender causing the problem?
Try running the same file through an older version and see if it goes faster.
If you have more stuff on your comp than you used to that could be responsible for the slowness.
