sadly the game optimization overall its very poor, The framerate on top end machines never exceeds 50fps, unrelated to the game setting, i have tried to lower image/hair quality and i have 0 fps increase. The game itself is not moddable... What we are doing with thora and commonfactory is pushing it beyound its limit in order to make it look better. The asset optimization its not possible (at least to my knowledge) without changing some game settings from the developer... i did try to contact him, but he never reply... so really we are doing what we could with what we haveUsually ~50 fps, with The Bedroom asset loaded, usually 21-34, depending on which poorly optimized light source I'm facing.
also i did play with the light settings a lot but im not sure im willing to sacrifice the shadows quality to gain 3fps
but if you are having any suggestions on how to improve the assets am always available on the game discord
