Hello, I'm not sure what is exactly working here, my guess is that the game does not like it when you have Lighting on Medium or above without Post Processing Effects on?
I'm getting a lot of FPS issues even after putting the resolution down on my iMac down to 4K than I had before, I still have the Edge Smoothing on low, reflections low, visual effects low, objects medium, uncompressed sim textures off.
When you change the settings to as close to mine as you can get does it get rid of the problem? Or at least mitigate it? But when you do you get fps drops? Sorry, I don't full understand your post.
