Green bar not full

When I press CTRL-F twice, a green bar appears in the top left-hand corner of the screen. I understand that it shows GPU activity. My bar is 75% green. Is this correct or should the bar be 100% green?

 

It should be 100% if you are not using vsync and/or not being CPU limited.

 

The single green bar I have never seen before this update,I’ve only seen the green and purple bar

 

-green bar on the left is memory usage
-green bar on the right is gpu usage(if you have vsync on it will be full & without sync it will be full.only if you have set max framerate to 60 or more in player json without vsync,you will have green bar on on lower % till your frames drop below 60 fps..)
-purple bar is cpu usage

 

As @kiko0602 says, you're looking at the memory bar. The CPU graphs showing utilisation for graphics and physics are shown via Ctrl-C.

 

Thank you for your replies. So, the green bar is telling me that my PC is using about 75% of its memory? That sounds good.

Looking at the CPU graph, the green (GPU) line goes all the way across, but the purple (CPU) line goes halfway across.
