I was getting some heavy FPS hits in my Highrise condo recently, so I decided to try and investigate what was going on. I reset the condo so there was nothing else interfering with my test, and I found that just being around or looking at the pool dropped my FPS from a comfortable 120 to around 90. Even a lightly furnished condo made it drop even more, down to around 70 FPS. At least from what I could tell, just having more items in the condo caused the water to tank the FPS more than by itself, as I haven't even added any items to the pool room itself. Now, I get around 30-40 FPS in the general area of the pool with my normal condo layout. I even tested the Condo condo, and those pools don't affect my FPS at all. Is this something on my end, or is this an optimization issue?
In case it helps knowing, I have an I7 6820HK and a GTX 1070.
