You can write your topic however you want, but you need to answer these questions:
What do you want to achieve? Keep it simple and clear!
I’m trying to achieve a large-scale game with streaming enabled.
What is the issue? Include enough details if possible!
Even though only around 3k parts are in the scene, I struggle with render fps and network fps.
This game is 140k parts currently, hence the need for partstreaming. its a driving game, and so i need it for it to function.
Im getting 20fps all around the game; regardless of graphics level.
What solutions have you thought of so far?
Setting collisions for unnecessary parts to cancollide off, box collisions, cantouch/canquery off
unions and meshes set to renderfidelity automatic
Essentially, reduce polygon count where ever you can, and if you game is lagging terribly after, there may be something wrong with your code or the models that are the main focus of the game.
