Help for optimize game

Hi community,

I need help to optimize my poject, I’m ready to send via a swiss transfer link anyone who could explain or help me find solutions. I’m currently developing an open-world video game representing the island of reunion, it’s a racing game with drag races, races etc… we can also be in third-person view.

i’ve managed to have an imposing landscape of over 1000km2, i’ve got roads, buildings etc…, i’ve managed to optimize my project. I’ve managed to optimize as best I can, with my machine of course (RTX 3090, 256g ram, threadripper 3975 pro 32 cores), I get out of town Vram= 5.4go; Ram 4 to 5go FPS 100 110 then in town Vram 7 to 8go, ram = 4 to 6go Fps 70 80

in UE5.3 FPS constant 50 to 60.

I confess I don’t really know how to use unreal insight, but I’ve optimized the materials, textures, tested all the commands (stat unit, stat fps, stat scene rendering) checked the drawcall etc… optimized the landscape with hlod + nanite, adjusted the lod too, optimized the mesh, I only get green when I’m in shaders quads and complexity mode,

have any of you already managed to package a project and optimize it? if so, I could send you my project package in dev version and see together what freezes at times (yes, only in certain places do I have an incomprehensible drop) I’d like to understand in order to evolve on my project, knowing that I’m integrating my ia traffic at the moment, then npc manager for the ia in town, then vertitably the gameplay with the different races etc…

best
