on amd gpus it won't draw anything at all unless you have the entire ray tracing pipeline set up fully and correctly:
- have at least rgen, rmiss and rchit shaders
- set up shader groups to reference them
- set up sbt to reference shader groups
it is not enough to just have a single rgen shader operating like a compute shader. amd will have a shader preamble that checks for something and exit early w/o actually running any shader code you wrote
meh
