Good computer, good windows performance, terrible Ubuntu performance?
NVIDIA has always been problematic. I understand that, you have already updated the drivers, but here is another process of doing it:
- Open Terminal and type
sudo apt-add-repository ppa:xorg-edgers/ppa && sudo apt-get update && sudo apt-get install nvidia-current nvidia-settings - Go to Additional Drivers as you did before
- Choose the latest driver (Open Source) and restart
- It worked on 14.04, hope it works
