Thanks for the report! :D It's likely that 900 series NVIDIA cards do not support the variable shading rate extension that this application uses. The feature that uses it is currently not automatically disabled on non-supported hardware as the application is still very experimental and current priority is expanding the feature set.

You can try the v0.4 release which does not have variable rate shading. It includes more or less all the other functionality of the latest release.
