I'm hitting very high GPU usage(97%+) and ~40 FPS in particular areas. (Main office, the upstairs hallway and the area near the door to the garage)

The performance issues seems to be related to lights. As I can feel a significant impact to the framerate when I turn the lights on the upstairs hallway on, and lights in the ground floor hallway has a lower but still noticeable impact. Without lights, I can maintain 60 FPS without issues.

I then played around with the settings, but even with shadow set to 1, I still can't get a consistent 60 FPS. I then spent hours cleaning up the base, but did not notice any improvements.

I booted up 0.8.2 just to be sure I weren't misremembering things. And sure enough, no matter what lights I have on and off, how cluttered the base is, GPU usage remained around 70% and FPS is always at a smooth 60.

I'm running the game at 3840x2160(4k) with a 11900k & RTX3090. I have tested DirectX 11, DirectX 12 and Vulkan. DX11 and DX12 performed similarly, while Vulkan gave me much lower framerate.

Wondering if anyone else is having this problem
