How to improve gaming performance on laptop?

Once the heat builds, the processor, GPU, and most other components will slow down. This doesn't make for an effective gaming machine.

Regularly clean your laptop

Update your drivers (especially for the GPU)

Install the latest version of DirectX

Overclock the GPU

Optimize the power settings

Activate Windows 10's Game Mode

Close background apps

Check the network speed for online gaming

Upgrade RAM capacity and changing the HDD to a SSD. Those are the only options available with laptops. You can also increase the cooling capability with cooling pads, using glass or aluminum surfaces etc. This will reduce the chances of thermal throttling.

improve as a rule more ram , or a faster cpu , depends on how old is the computer .

If you can increase the ram, you should do it, and add an ssd. I wouldn't recommend upgrading your cpu or gpu even if you can.

Trade it in for a gaming desktop

Simply put, buy a gaming laptop or pc

The parts to make it better usually cannot be changed out

To improve gaming you need to play regular games and take training .

Generally there is not much you can do....

just buy a better laptop OR go with a desktop

depends on the laptop and the cpu and ram inside
