Well, the problem is that I've been using Opera GX, but i noticed that everything like pdfs videos, were lagging a bit. Then i opened up the task manager and found out that the browser was using my intel gpu instead of my nvidia gpu. so i set it to the dedicated gpu on nvidia settings. NOTHING. still used the intel gpu. so i tried turing it on from graphics settings. STILL NOTHING. So even after i set my gpu preferences, it still uses the integrated gpu, no matter what.
Also, the dedicated gpu works on browsers like Edge and Chrome when i set it,and even though opera gx is also chromium based, it doesn't work on that.
Please tell me how to make it use the dedicated gpu.

Intel i5 9300H
