Alright, well then it sounds like what it needed, is to downscale the texture resolutions. For some of the initial 4k games, they'd upscale a 720p, 4 times, instead of naturally do 4k. The reverse might be beneficial here, of downscaling the textures to reduce the load.
Or, you could convert the avatar mesh into sprites, and load different sprites at different intervals based on the conditions required. This would significantly reduce computational costs. A lot of older games would take 3d meshes and convert them to sprites to do things.
Or, you could look into how ID Tech 4 managed to do megatextures (a form of virtual textures) and how they managed to get them to be so well optimized. Like I think an entire level was one single megatexture, for like Wolfenstein the New Order, and it was quite well optimized despite being so big.

Well POV might be useful for providing lewdness, while still supporting a 1st person "style" of combat. I seem to recall skyrim doing something of the sort for melee/ranged combat, while having that POV ability.

Hmm. A picture of what you are referring to with the hips would probably help to explain your point better. We might be referring to two different things.

Do more things... like mantling? sliding? using cover effectively? flushing you out with grenades (FEAR style)? talking with eachother (FEAR style)? Getting grabbed by environmental hazards like tentacles?

Any plan for butt pregnancies, such as via oviposition?

As for pregnancy ideas:
-> Having her stumble/wince in pain, on occasion. More frequently, the more tentacles present.
-> Having them leave her body, requiring her to stop somewhere and push them out... and refusing to do so, causes penalties.
-> Having the occasional tentacle burst out, then slither back in.
-> Having the occasional egg slide out or get pushed out.
-> Having a larger belly slow her down, make it harder to crouch/get up, deactivate sprinting or jumping, kind of thing.
-> Having her hole remain permanently agape or agape for a period after sex.
