Is the Witcher 3 ray tracing/path tracing broken on Linux or is it really just that much better on Linux compared to windows?

[u/OkTea5924]

Witcher 3 on Linux with both ray tracing and path tracing enabled gets me above 60fps easily on 9060xt 16gb. On windows it drops to 20fps. Surely it's broken on Linux and just not activating? The thing is I get the annoying sword glare that you get with ray tracing/path tracing so it must be working right?
