For me the map is essentially unplayable, as it gives constant fps drops at any time. At times it seems like it is simply loading the map and then starts to go to the performance I have on other maps, but then it goes back to that stuttering and fps drop. It doesn't matter if I look at the sky to have nothing rendered or where I am on the map, this cycle from running for a few seconds at normal performance to stuttering no matter what I do continues.
It also struggles especially more than other maps to load.

I want to say against me that my PC really isn't ideal for playing Unturned in the first place, basically I have to have everything at minimum and ridiculously low resolution to have 22-30 "stable" fps. I play on an old HDD and with an IGPU. I am fully aware of this and know that I play at my own risk. I know this should be enough to say "it's your fault", but this is where the problem lies as with other large maps or Workshop maps with similar level of detail nothing like this happens and I can play completely normally. No stuttering, no FPS drop, nothing, but with Rio it's hell to even load the map.

I'm confused whether this map is simply not for me, poorly optimized, or a mixture of both.
