Chrome --enable-precise-memory-info doesn't work and performance.memory is still bucketized

I have to test memory usage of some pages in Chrome on Windows programmatically.

Here is my Chrome version (60.0.3112.113 - Official Build - 64-bit) enter image description here

Following Chromium Command Line Switches Documentation I ran Chrome with --enable-precise-memory-info flag:

enter image description here

Then in the opened Chrome instance I tried to check value of window.performance.memory.usedJSHeapSize

but looks like inspite of --enable-precise-memory-info flag this info is still bucketized.

enter image description here

even in Chrome Task Manager (Shift + Esc) I see that memory usage is grows up by about 1 Mb after each execution of:

for(let i=0;i<100000;i++) {a.push('sdftgkljhghertyukytedtreut56ytirty7uikty' +i)}

I found only one outdated discussion concerning this issue even if the issue exists I would expect to find more discussions online.

If I do something wrong - what is my mistake?

If this flag is not supported anymore then what is the new correct way to do it?

Thank you!

maybe you need to close all opened chrome window (cmd + q) before run /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --enable-precise-memory-info
