low fps, not VR optimised

[Mucka]

Hi, I purchased this aircraft for VR mainly and though it is a great aircraft on monitor it has not been optimised with VR in mind.
I get 20% less frames than Xplane stock Cesna which is huge when you need all the resources you can get for Xplane VR.
I appreciate it has high fidelity pbr textures but 20%?
Also the windshield weathering and dirt look fine on monitor if a little overdone for my tastes but they are horrible for VR where clarity is already impossible to achieve.
If it possible to have this and other aircraft optimised better for VR or have a VR option within the package and to have future aircraft built with VR in mind rather than just being made VR compatible?
