??? - nothing we can do without info!
1. WHAT Hardware - there are 1000 models out there...
2. if its APU only (no dGPU) you need fast dual-channel ram (2 sticks)
3. if it has dGPU and performs bad there are many ways to fix that
4. do you play "unplugged" (so ONLY on battery) or did you plug in the power? - 85% der Laptops need power to run full performance
we need to know what laptop hardware you have...
some Laptops can be overclocked
some GPUs can be overclocked
dual-channel ram is nice in a laptop - especially with an APU
