VB Compiz Transitions are slow

Question

I'm using i3 and Compiz with Ubuntu. Though Compiz animations just as simple as fading in and out seems so sluggish.

My computer has a GTX 970 and a i7-4770k with 8GB RAM Corsair Vengeance. Is there any way to make it not as laggy / sluggish / slow? I'm running Ubuntu in a VB for a work environment so when I'm done working, I can easily switch back to Windows (granted my boot time is only 4 secs with a ssd, but it's still time I have to wait).

My Ubuntu VB settings are:

4096MB RAM
4 CPU Cores being used @ 100% exe cap.
Max VRAM (128 MB) with 3D acceleration on.

Unity (Ubuntu's default desktop environment) is a relatively demanding DE, and requires a good graphics card and drivers to run well.

Unfortunately, the 3D video drivers for Linux when inside a VM are terrible. Even VMware who makes a commercial virtualization solution doesn't provide 3D drivers.

The best fix here is to install a different desktop environment. For example, XFCE would be a good choice.

In order to do that, just open a terminal and run:

sudo apt-get update
sudo apt-get install xfce4

Also, you did install the Guest Additions kernel modules in the VM, right?

Guest Additions, like mounting the Guest Additions iso and installing them? If so, then yes. – ErraticFox Aug 13 '16 at 18:15
@ErraticFox - Correct. – You'reAGitForNotUsingGit Aug 13 '16 at 18:17
I'd say 'relatively demanding ' would be more accurate and concise then the awkward "EXTREMELY demanding (relatively speaking)". – mikewhatever Aug 13 '16 at 18:18

I'm still new to Linux, so can you answer what's the difference between a WM and DE? Because don't they both technically "Manage Windows"? I always get, not confused, but in a way confused as you're able to use both at the same time. – ErraticFox Aug 13 '16 at 18:19
@ErraticFox - See here for an explanation: http://askubuntu.com/questions/18078/what-is-the-difference-between-a-desktop-environment-and-a-window-manager – You'reAGitForNotUsingGit Aug 13 '16 at 18:21
@ErraticFox - Also, if you want a lightweight DE and a lightweight WM, you should install the LXDE DE since it uses the OpenBox WM. – You'reAGitForNotUsingGit Aug 13 '16 at 18:25
Wait, I was using i3. So was Unity also running in the background? Because I was really enjoying i3. – ErraticFox Aug 13 '16 at 18:25
@ErraticFox - As far as I can tell i3 is a WM and not a DE. – You'reAGitForNotUsingGit Aug 13 '16 at 18:28
