What kind of GPUs don't have readable depth support?

According to documentation:
urho3d.github.io/documentation/1 … paths.html

using HWDepth is a bit faster, but it won’t work on some GPUs. What kind of GPUs is that? I’m not sure if I’m googling it right, but it seems like pre-2006 ones.

Should I even bother about supporting them?


So it looks like generally hardware from before 2010 might not have it. Also I know some versions of Intel HD graphics don’t support it. So at this point it’s worth keeping support, or you’ll get people like me who still can’t run those particular Render paths.
