Do you need any special driver for the shape match mode?

from the docs (I assume newer versions will also be fine):

https://www.sidefx.com/docs/houdini/news/19/vellum.html
Shape match constraints require the latest driver for NVIDIA Ampere series cards. This is version 456.38 on Windows [www.nvidia.com] and version 450.80.02 on Linux [www.nvidia.com].

If you don’t update your driver, you can alternatively set the following environment variable to disable this feature: HOUDINI_OCL_FEATURE_DISABLE=CL_DEVICE_DEVICE_ENQUEUE_SUPPORT. For more information, see environment variables. [www.sidefx.com]
