Currently not running on Intel Arc GPUs

[Azralee]

A fellow member in a discord server I'm in tried to run the latest released version on an A770, but it didn't start. With a debug build using the current master commit 164e530, it produced the following log:
Crashlog.txt
Here is the vulkaninfo report for his card:
vulkaninfo.txt
He is using the currently latest driver v31.0.101.3959 on Windows 11.

Ah, excellent! I was wondering when someone would give a report on Arc.

As a side note, I'm curious why your debug build is not properly showing the stack trace (you should get function names). Do you have a pdb files next to the executable?

[GPSnoopy]

From the vulkaninfo.txt file you have sent, it looks like shaderInt64 is not supported:

RayTracingInVulkan/src/RayTracer.cpp

Line 82 in 164e530

deviceFeatures.shaderInt64 = true;

This was added as part of the heatmap feature: 40cea9f

According to the official specs, clock2x32ARB() could potentially be used instead? Though that will require another way of calculating float(deltaTime) / heatmapScale. I won't be able to test this theory for a couple of weeks though, PR is welcome if you want to beat me to it.

Best case would be if Intel drivers support it in the near future.

He probably forgot to extract the pdb file as well.

Hmm, I can take a stab at it. It shouldn't be too difficult to make this work. Should only be a couple of LOCs.

Agreed.

Interestingly, this seems to be a Windows only problem. According to various Google searches, the feature is available when using the Linux drivers.

Hi I have A380 on Linux and its still failing
