Launching Zetalab fails silently #5

Closed Firesampo closed 9 months ago

Firesampo commented 9 months ago

Hi,

I've now tried building & running this using two different machines (a really beefy NVidia A6000 desktop machine, and an RTX 2080 super laptop), without much success. I'm using VS 2022 version 17.5.2 and CMake 3.25.1.

On both machines I'm able to build the solution in VS 2022 without errors, but when I launch the Zetalab app using cornell box gltf as the test scene, it just flashes up for a half a sec (I can see an empty app frame for a while), and quits silently without any error.

I wonder if there's some step(s) that I'm doing wrong, or am I missing something? Can you share a build I could try?

Hi,

Since I can't reproduce the issue on my system, I'll need more information to pinpoint the problem. Could you try building and running the project in debug mode? There are many assertions that are compiled out in the release build. If one of them is triggered, then I'll have a better idea of what's the issue. If this doesn't work, try adding a breakpoint in ZetaRay/Samples/ZetaLab/ZetaLab.cpp around line 53 (initialization) and step through the code to see where it fails.

I can share prebuilt binaries, but I doubt that would help; the issue seems to be something that's triggered under certain hardware setups.

Hmm, could it have sth to do with this?

exception

Edit: yep, this is it => I commented out the STABLE_GPU_POWER_STATE define and it runs now.

Glad to hear it's working!

SetStablePowerState() requires the machine to be in developer mode. I just realized that I'm assuming that to be true by default. I'll change it to off.
