Ways to increase performance on an old laptop

I’m trying to increase the fps as mush as possible to run on an old laptop. ori and the blind forest does pretty well but it was made with unity .

I did:

MyGameSettings->SetScreenResolution(FIntPoint(640, 480));

Material Quality: low

Engine scalability is all set to the lowest lowest

I disabled light shadows

Turned off Vsync

Deleted all light options except directional light

Anything else that can help?

i would get a graphics card for it myself
