Cosmos VS UIforETW

I didn't realise that. Then again, I only experimented with AOT executables quite briefly. Perhaps Cosmos[1] stuck in my head more than what I read about AOT dotnet applications.

there are entire toolkits for that! https://github.com/cosmosos/cosmos

This is about the same time that Cosmos came about - they’ve got they own ASM-like flavour of C# called X# and IL2CPU

I recommend you to take a look at the Cosmos project. It's an operating system construction kit integrated to Visual Studio using it's own compiler translating IL code (C#, VB.NET, F#...) to x86 assembly.

From these lines of code one would assume so, but apparently Cosmos seems to be quiet more serious than just a simple shell.

You can use UI4ETW[0] to capture an event trace when the mouse freezes. You may need to install the Windows SDK or Visual Studio to interpret the results, though.

Event Tracing for Windows (WPA/xperf) works quite well for profiling, and it's really easy to set up with UIforETW. Symbol loading works with MSVC-generated symbols (just set the target/debug/ folder as a symbol path), though it's rather slow.

There's a couple methods to achieve this but I like to recommend this project since it provides an easy to use GUI and (iirc) doesn't require the installation of Windows ADK.

If anyone could use UI for ETW (https://github.com/google/UIforETW/releases) to grab an ETL file during the micro-stutters and share it with me, that'd be amazingly helpful. An ETL is like a whole-machine tracefile that'll show exactly what chunk of code is using the time when a stall happens.

Install UI for ETW (https://github.com/google/UIforETW/releases) and collect an ETL file while the stuttering is happening. Upload them to somewhere and send it to JeffHill once you got them.

If you capture an ETL file using UI for ETW (https://github.com/google/UIforETW/releases) and link that ETL file in the report, I'm happy to take a look and see what might be going on?

Could you install UI for ETW and collect an ETL file? https://github.com/google/UIforETW/releases

If you install UI for ETW (https://github.com/google/UIforETW/releases) and capture an ETL trace during gameplay, I'd love to open it with dev tools and find out what's going on! It sounds like you've done all the obvious things, so I'm pretty curious what's actually going on with your system. With a rig like that you should have no problems running Dota at a pretty high frame rate.

If you're seeing poor performance in Dota, one thing that's incredibly helpful is to install UI for ETW (https://github.com/google/UIforETW/releases) and collect an ETL file during the problem. We can read these files to see which parts of Dota are misbehaving or what else on your system might be interacting with Dota.
