Will the FPS in my game be different on other peoples computers or is it set from my computer?

Hello,
If the title question was too confusing ill explain more

I have a scene in my world with a lot of grass and foliage, ive done what I can but the average fps is about 20.

I think my computer is below average for gaming but unreal engine itself works pretty well.

So when I publish my game, will the game be set as 20 fps or would an average computer have the game run at a better

It will be different on other computers. There’s a setting though where you can set the maximum framerate

Alright thank you
