I think you never played to sexy beach premium resort, the first game of illusion made from unity3d engine. AA series, AGA3 so on, the old illusion games used a they own game engine before they awap to another engine, the problem isn't unity3d. And don't belive the problem is only AI here eh, HS1 do the bad shader setting, that game suffer a lot. but thanks to HSUS the game is better, PH still have a bad game optmize, KK share the same fate here, but thanks to the modder the game is more stable, EC have a bad optmize to the bad shadow settings and light....AI to the bad infinite draw, in the island, funny fact the studio neo 2 isn't heavy like for the main game and some modder have fixed frame drop, same fate for HS2.... The worse game optimize still is sexy beach premium resort.
RAM for gaming is fine IF you need recorder, chat, rendering in same time. But if you need only play games the ram is your last thing that you need worried about that.
i have a better perfomance from DMC5 that from any other illusion games.
I wouldn't leave Unity out of the equation of optimization problems, a lot of pre-2020 versions of Unity aren't the most stable or optimized builds.
Hell, Genshin Impact was using Unity 2017/2018, and for a good while the game ran atrociously even at minimal settings. Oddly enough, some people (like myself with my RX570 4GB) had zero issues running at 1080p with max settings. Others with far more powerful Nvidia cards couldn't run the game more than a few minutes.
I love Unity for its ease of use and portability, but man, it can be hot garbage at times.
I have and still do play SBPR to this day with none of the issues I hear complaints about. I have played and still do play basically every game Illusion has ever made that isn't just a VN.
I'm aware they used their own engine before switching to Unity with Harem Mate and Honey Select 1, that's why most of their games have to use a .dll in the game folder so they don't lag because of Windows 10.
The problem isn't Unity, but it also isn't optimization issues except in AI Shoujo.
The bad shader thing in Honey Select 1 was an Illusion issue, though like I said, I never had it and it did get fixed.
Play Home works just fine, no problems in that one.
Koikatsu works just fine as long as you don't run too many students for your RAM to handle and I run a copy with only the translation, no mods for performance, so that copy is running the unmodded performance levels you claim are not good.
Never played Emotion Creators because it is basically just a studio with no attached game, but considering it is based off of Koikatsu, I doubt it was poorly optimized.
AI Shoujo definitely had issues with the fact that it draws literally everything at all times, even unused assets. That's why it lags, because somebody at Illusion forgot to remove island assets that the players have no access to and the game is forced to draw those island assets in a place the player cannot see.
The shadow and light settings in the studio aren't bad, they just require a lot of work to get right. The studio IS NOT for the people looking to just mess around.
No, the worst game is still AI Shoujo in performance.
The issue in Koikatsu is RAM, all students are loaded into RAM, so every student means less FPS once you reach a certain amount. That is a poor design decision because it doesn't allow for a computer with dedicated graphics to use those to load the students and get great performance even at a higher student count, but it is not an optimization issue.
Still, I have never been below 40 FPS in this game.
The fact that Metal Gear Solid 5 can run better than KK is something to be worried about
Try running MGS5 without dedicated graphics, you'll see just how bad it runs. Far worse than Koikatsu, at least Koikatsu can run almost exclusively on RAM at a consistent 40-60 FPS. You also have to take into account that MGS5 is a game by a large company developer, Illusion is A LOT smaller than Kojima Productions and Konami.
