Not a "bad" scenery just ini consistently struggles to optimize their products for a wide range of computers and devices. I have an Alienware R9 aurora with 16GB of Ram and RTX 2070 processing and can't get above 20 fps unless no other addons are injected into the sim. The product looks stunning as all of their works do but hopefully they will update this and many other of their works to help with the LOD optimization that kills performance for many :(
