Worst part is Nsight shows up completely normal. Maybe this is some kind of driver issue?

"8+ years exp graphics dev learns to actually profile stuff" status update:
After some guidance I decided to re-fetch chrome sources and now it builds without problems (3 hrs in, 70% done).
Also I downloaded actual Nsight Graphics and fed my game into it, now trying to make sense of the results

Wait, it's not even the right thing I've downloaded! It's Nvidia Nsight Systems, which, contrary to the name, doesn't actually do GPU profiling. You need Nvidia Nsight Graphics for that. And of course all online info just calls it Nvidia Nsight, because, I guess, uuhm, yeah, idk

Nsight Graphics' GPU Trace/Trace Analysis often provides more low level hardware information, in the form of tooltips and performance advice, than the documentation available online does, worth exploring a few captures to understand the GPU architecture better.

And for god's sake don't attach an SQLite database tutorial PDF, a copy of the White House maintenance magazine Tholos, and a binary update to the Nvidia Nsight graphics toolset for Ubuntu 20.04.
Sure all these things are under 10MB and CAN be uploaded, but I'm saying, don't.

I never noticed the geo cutout in this stage. It's such an elegant solution.
To my knowledge, MGS2 doesn't really use stencil shadows in these cases, but simply renders any relevant meshes from the light's pov and then blends it onto the scene.
Nsight seems to confirm this.

Try a gpu trace rather than frame debugging if you want to profile, NSight is not easy to learn but definitely the best time investment if you want to get serious about optimizing!

Actually, this was with locked base clocks in NSight.
Using GPU timestamps, it's really more like 9.3ms (4.3ms for lighting, 5ms for DLSS-RR).

I was working on a Vulkan project, using RenderDoc and Nsight, and started thinking: what if I ported the WebGPU Inspector debugger I wrote to native. So I started working on that. Vulkan, D3D12, Metal, on Windows, macOS, Linux, Android, Quest.

You can actually measure if ROPs are the bottleneck of your system with NVIDIA’s Nsight Graphics tool.
Using GPU Trace, you can see a crazy amount of information about how a frame is rendered.
If ROP utilization is high, with other units unsaturated, well...there's your bottleneck :)

Not sure where to ask this, so...
#graphics folks, has anyone used Nvidia Nsight on Linux successfully? On my machine the profiled app crashes at startup (only under Nsight). I've traced the issue to XOpenDisplay returning null (though the DISPLAY env var is ok), but that's it.

The GPU clustering itself runs at about 110 μs, a speedup of 30x over Bevy 0.18 on this stress test. It automatically resizes the clusters as necessary for best performance. There are no arbitrary limits on the number of lights or clusters. The same system handles light probes and decals too.
