sub-surf's slow down blender

I am using sub-surfs to created a character, however when I turn on subsurf blender starts running really slow. Is there a way to speed this up? WOuld it run quicker is i converted it to a plain mesh? Or is it just htis stuipd OS X 2.23 version of Blender? I know it will be good to get a copy of 2.25 when the source is opened!

There’re two subsurf numbers below the subsurf button. One is how high to subdivide the model during editing, and the other is how high to subdivide for modeling. I keep the editing number (the one on the left) at a 1 or 2 on my iBook, and for rendering I go as high as 4 or 5. Higher than that really isn’t necessary IMHO, and it slows the system to a crawl to create that many faces.

Hope this helps.

What kattkieru says is true only in 2.25

2.23 does not have a control on different Subsur levels for rendering/modeling.

Unless your PC is powerfull any subsurf beyond level 3 will slow it to a crawl because Blender needs to do calculations and handle all those additional vertexes.

Remember that, if N is subsurf level each edge
is splitted into 2^N subedges and each (Quad) face into 2^(N+1) faces!!!

Hehe, my bad. I never used 2.23 seriously enough. :o
