Foliage and fog artifacts

Hi all.

I am hoping someone can shed some light on an issue I'm having. Overall my stream quality is amazing. However certians scenes in games Ive noticed a dip in quality or rather some artifacts. For example scenes with heavy foliage like in Horizon forbidden West. Also scenes with smoke and fog. I'm wondering if it's an encoder thing. I have an AV1 capable tablet on order and hopefully that fixes the issue. Has anyone experienced this or a possible fix. My specs are below. Thanks in advance.
