Blender 64 bits

Support Basics & Interface
1

I’ve just install Blender 64 bits on Ubuntu amd64.
I have also install normal Blender via Synaptic.

Blender 64 bits runs slower than Blender bf and using “threads” on or off doesn’t change nothing !! (amd64 X2 3800+)

What version of 64 bit blender are you using? Is it an official one, or from the testing builds section?

Is it less responsive, or is it just the render times?

How much do they differ by?

Give us something to go on!

and are you sure that you actually installed a 64 bit build of blender?

The testing binaries Linux x86-64 from download section of blenderorg aren’t 64 bits ?

The testing build from Garphicall doesn’t work for me.

The rendering time differe : 55s/45s …

And waht about “Threads”, it doesn’t change nothing in the rendering time with amd64X2…

Testing builds are often done more to check compatability, and are generally not optimised.

Try building it yourself, and play around with different compiler options, you should see an improvement.
