Question How to show 3 decimal places at profiler hierarchy

Currently at profiler hierarchy it only shows 2 decimal places like 0.01ms. Any way to make it show in 3 decimal places like 0.001ms?

 

The Unity profiler is not reliable enough for micro-profiling.

First, no matter if you profile in the editor or in a built player, you're running with many fundamental mono optimizations disabled and you're running a version of the native unity code that has a ton of overhead.

Moreover, measuring call time on the order of 0.01ms or less is completely unreliable over a single call, you need to average results over hundred of calls (and ideally over multiple sessions) to get a reliable figures, especially if you intend to compare those figures between implementation variants.

The profile analyzer does provide good tools for the latter, but you still need to keep in mind that its figures are massively skewed compared to a non-dev player build. The only 100% reliable way to micro-profile your code, especially heavy C# code is to implement your own profiling instrumentation with

Stopwatch

I already see way too often people coming to very questionable conclusions due to misinterpretation of the single-frame results of the profiler, increasing perceived accuracy by adding another decimal place would be a bad idea IMO.

 

Thanks. Btw just let u know actually at profiler switch to timeline view it's in 3 decimal places. I think it's even better if official can add an option to switch to microsecond unit and millisecond unit back and forth.
