GPU Statistics for iPulse

In the next version of iPulse, I'd like to show GPU statistics. Unfortunately, the format
for these statistics is vendor specfic (see the "Performance Statistics" dictionary below.)

In order to cover as many devices as possible, I'd like you to run the following commands
from your Terminal:

$ sysctl hw.model
$ ioreg -r -d 1 -w 0 -c "IOAccelerator"

You can help me read the results by putting them in a code block (triple backticks).

I'll add a few of my Macs to get this list started. Thanks for your help!

Here is the code I landed on:

NSNumber *gpuUtilization = nil;
if (performanceProperties[@"Device Utilization %"]) {

}
if (gpuUtilization) {
	long rawGpuUtilization = gpuUtilization.longValue;
	if (rawGpuUtilization > 100) {
		rawGpuUtilization = rawGpuUtilization / 10000000; // scale down "GPU Core Utilization"
	}
        ...

Thank you so much!

This is almost exactly what I've landed on as well. Turns out some newer GPU drivers also have a property called "GPU Activity(%)" which is pretty much the same as "Device Utilization %".
