5.4.3 Profiling Help - App Runs Very Slow compared to other devices

Hello, Team ML!

It is time!

I am upgrading my flagship app Virtuoso to ML5.4.3 UE Branch and working toward a standalone application. After lots of messing around, I have gotten it to build and run, but it lags very hard.

I have worked extensively with ML2 and have made a fully functioning complex app that runs just fine, however Virtuoso lags very hard, even on the menu, which by default is a black void with nearly 0 activity but the UI.

This is odd because Virtuoso is designed to even run on phones, and can run on an Android or a Meta Quest 3 with solid FPS, so there is something platform specific potentially causing the issue, and I know the ML2 is a much faster device than the others it runs on, so I am curious what could be causing it.

I have tried the RaedonGPU Profiler, but I don't really know what to look for or how to use this. I have uploaded the capture here, and if there is any guidance that can potentially be drawn from this, I would appreciate it.

Hi @VirtuosoCEO,

I'm sorry that you are experiencing this. I would recommend checking out Unreal Insights. This tool should help you identify bottlenecks in your application.
