On the [url=https://developer.nvidia.com/nsight-graphics-requirements]Nsight Graphics Requirements
page[/url], it says it supports OpenGL 4.2 through 4.5, but it looks like Handmade Hero is currently targeting OpenGL 3.3 (and uses functions that are not in the core spec in version 4.5).
Of course, if that's what the root cause is then Nvidia ought to diagnose it instead of just falling over.
It looks like we might need to either:
(1) start targeting OpenGL 4.5, or
(2) revert back to the previous version of the Nsight plugin (and I guess the driver to match).
