View Full Version : [ubuntu] Dramatic improvement in unity 3d performance

June 14th, 2012, 08:41 AM
I was experiencing extremely poor performance in unity (especially slow rendering while drawing in gimp) and I fixed the problem but I'm not exactly sure how.

Since unity was performing so poorly I decided to switch to gnome classic. The process went like this:

1. Installed "gnome" package
2. Realized I should have just installed "gnome-panel", uninstall "gnome" and "gdm", reinstall "gnome-panel"
3. Logged into gnome classic session, performance problems solved, gimp is FAST.
4. Logged back into unity shell... performance problems solved there too!

I would very much like to know what package I installed (maybe a dependency that I am not aware of?) that fixed my slow rendering issues. Poor performance in unity seems to be a common issue so a clear fix would be remarkable.

My video hardware from lspci output reads:
