How to make my game run better on low end computers?

Hey so I’ve been trying to make my packaged game work better on low end pcs so my friends can play it. I have a pretty powerfull computer so it runs fine on mine. any way the step I took to optimise my game was remove all unneccessary polys, import them as individual objects instead of my level as one huge a joined object, make the project settings scaled instead of maximum, and enable world partitioning. These were my results.

without optimising
cpu: 27%
memory 6.5gb
gpu:13%

with optimising
cpu: 15%
memory 6.3gb
gpu:100%

Does worldf partitioning use a lot of gpu? I just don’t know what would cause such a jump in gpu performance?
Thanks in advanced

When you change the level from one obj to many
the texture draw calls went from one to many
you can change the texture image import size by double clicking a texture.

don’t have enough info to suggest more.

I figured it out! I had to set my frames per second to 25! I think it was uncapped before so that explains why on even rtx3080s it was maxing out. now I’m getting about 30% gpu usage.
