Hello,
I have encountered device hang problem in our engine which I have no explanation for and I’m suspecting it is driver issue.
It is caused by particular succession of DX12 commands, involving timestamp queries and copying of buffers on compute queue.
I have prepared minimal reproducible sample:
Executable
Project
So far this sample crashes on:
GeForce RTX 3070, drivers 511.23
GeForce 3060 laptop, drivers 496.13
Works fine on:
NVidia 2070 Super, driver version 511.23
NVidia GTX 1660Ti (Laptop), driver version 462.80
any AMD card we have tried it on
Can you confirm it is indeed driver issue?
