I have heard before people have issues with this GPU on laptops unfortunately, you may not be able to do much. You can check out this guide for settings help

How long have you had this laptop? If you never cleaned the vents I would start there. In the event that the vents are dirty both the CPU and the GPU could be downclocking, which in turn will lower your performance. Canned air can do wonders to fix those issues.
Maybe time for a new laptop if the above doesn't work
