Small update. View Frustum Clipping is now implemented but I am not yet happy with the results. It does work but I still see polys I think should have been clipped. So I am going to look into clipping at face level vs the cluster level. Might be worth it.

More or less tho. the test map I commonly used (featured in the pictures above) is now back up to around 60fps. Hopfuly with more optimisation I can get the entire map to run at 60 with no hickups.
