Dota-2-Vulkan VS UIforETW

Other than the CSGO issue, I think, for some placebo reason, gaming is better on gentoo. Maybe this is because since on gentoo you know what's in your system, you know what's wrong when something does go wrong? For example my personal experience is as follows: https://github.com/ValveSoftware/Dota-2-Vulkan/issues/397

Yes, happened to me as well, Manjaro, it is mainly because of Vulkan API, you can read my detailed bug report on the GitHub issue Here

Turns out, it's actually a bug in Dota's Vulkan implementation: https://github.com/ValveSoftware/Dota-2-Vulkan/issues/402

Texture issues: https://github.com/ValveSoftware/Dota-2-Vulkan/issues/388

You can check my profile I made a post on this sub about vulkan. I also opened a GitHub issue on dota 2's vulkan page. I too have to use -gl. Also my computer is better than yours (4c/8th, 5.7gb ram), so the possibility that your PC can't play vulkan specifically just got lower! Anyway if you want vulkan fixed make sure to make yourself heard on the GitHub page (if that's not against the rules, that is)! Here it is : https://github.com/ValveSoftware/Dota-2-Vulkan/issues/397

I opened a github issue but haven't gotten any feedback yet.

I've also had issues with Vulkan randomly crashing with a segfault. I reported it ~6 months ago but doesn't look like anything's been done: https://github.com/ValveSoftware/Dota-2-Vulkan/issues/382

Nope, Vulkan works great here for years (except long shader caching issue, but no crashes). Report it to https://github.com/ValveSoftware/Dota-2-Vulkan with proper info instead of vague angry posts.

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.
