Implement the option to cache/allocate RAM more agressively

Yesterday I installed Subnautica, and I absolutely loved the game. However, it stuttered like crazy. I have somewhat oldish PC, with only 6 GB RAM, Radeon HD7870 2GB. However I noticed that FPS themselves were okay, it was jsut the stutter that made the game unplayable (I turn my head, - bang - game freezes for half a second.). Naturally I decided that game was streaming assets from Hard drive, because my RAM was lacking. I went and bought another 3 sticks of RAM (4x3=12, yes, it's triple channel)
I came home and fired the game up - now I had something like 18 GB RAM and I was sure the stutters would be no more. I was wrong. They did lessen, but they were definitely there. I checked the Task Manager and 66% of RAM was free, Subnautica itself using no more than 2.5 GB.

Then Imoved the entire Subnautica folder (11 GB) into Ramdisk, and been enjoying seamless game experience ever since.
However, this is rather unwieldy solution, I have to manually copy the savegames from Ramdisk, and in case of outage all my progress would be lost. Then it dawned upon me that I was basically doing what the game itself should be doing - put the heavy and frequently used assets into memory, creating a cache and enabling fast access.

Why it is not implemented in the game itself (grab as many memory as possible and cache based on frequency)? Limitations of Unity? Any insights would be much welcome.

The fact that the game takes a huge data about textures from the game repository (folder with textures) and she is on the hard disk. This cache is not slow, and the fact that the media from which you want to transfer information to the cache. RAM quick. Much faster than HDD. Hence, the only two modern solutions for applications with heavy textures and open world: the RAM disk or SSD media. Developers will not be able to do more than optimize the loading of data from HDD to RAM. And even it will increase performance by 3%. Because they sell the application. And where you keep your personal business.

I just upgraded to an SSD in my computer and transferred Subnautica over to it. The load time was cut down by a huge margin. Used to take several minutes at least to load now it's under a minute I think. Between that and my new GTX 1060 the game is absolutely beautiful.
