More performance in Fortnite?

I play Fortnite on my PC, which I will upgrade a little soon.

But can someone still tell me how I can get better performance, less latency and lags.

Play on the lowest settings in my opinion.

Pc parts: Amd Phenom II x6 1045t

Gtx 660

GA-MA78G-DS3H mainboard

4GB Ram 2 × 2GB DDR 2

Do you mean FPS by performance?

Yes, or to avoid slight stutters

Do you play on the lowest settings?
update the graphics driver times?

I already have everything

Mmh write me a message is better
