MTuner

Some ten years ago I used an earlier version of https://unity.com/how-to/analyze-memory-usage-memory-profili... to accidentally discover a memory leak that was due to some 3rd party code with a lambda that captured an ancient, archived version of Microsoft's C# vector which had a bug. There were multiple layers of impossibility of me finding that through inspection. But, with a functional tool, it was obvious. Ten years before that I worked on a bespoke commercial game engine that had its own memory tracker. First thing we did with it was fire up a demo program, attach the memory analyzer to it, then attach a second instance of the memory analyzer to the first one and found a memory error in the memory analyzer. Now that I'm out of gamedev, I feel like I'm working completely blind. People barely acknowledge the existence of debuggers. I d

There's a kazillion tools out there. Here's a few off the top of my head to get started. RAD Game Tools Telemetry - http://www.radgametools.com/telemetry.htm Superluminal - https://superluminal.eu/features/ Remotery - https://github.com/Celtoys/Remotery Visual Studio's built-in profiler is an ok sampling profiler. It doesn't give you a nice multi-thread view which is a huge advantage to a span based profiler. MTuner is quite nice for debugging memory usage. Which is another gaping hole in the Rust ecosystem. https://github.com/milostosic/mtuner Lots of tools generate data in a format viewable by the Chrome trace viewer. I think Chrome's tracer viewer is not great. Maybe someday someone will create a viewer for the format that's good. I get cranky when large traces don't render at 60fps. Web-based viewers are almost all very very slow and
