Roman, Software-based rendering can be quite fast. And the way Compiz renders the screen is using buffer swapping (in 0.9.8 and later) which is implemented efficiently in most cases using page flipping. Page flipping is efficient even without hardware rendering.
(Showing my age) I remember when we used to render everything in software on 16MHz CPUs. It's possible for software-based rendering to be fast (although less common these days). However the main problem in this bug is the slow(er) software-based implementation of shaders in LLVMpipe, which Nux (and hence Unity) relies on heavily. So it is a problem specific to Unity, not Compiz. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1055936 Title: Unity is unusuably slow with fallback software rendering (LLVMpipe) To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1055936/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
