like i said, i had the SAME issues before i fixed the problem.

Yeah, I experienced a similar issue a few years ago with my wife's $1500 ASUS RoG notebook getting 4 FPS while playing Minecraft because it was using the wrong GPU. Not "a dip in FPS", not "minor issues in some areas"... 4 FPS as soon as she joined the world, using a high-end (at the time) 1060M to play Minecraft.

After applying the fix you describe, she was hitting 400+ FPS (until we turned the resolution back up to something reasonable), and the fans weren't even spinning up.

This was because the system was erroneously using the wrong render device, and taxing the CPU instead of using the dedicated GPU. A lot of people who have experienced the issue the OP is describing are using Ryzen CPUs (myself included)... which don't have a built-in graphics device, rendering your argument moot.

Stop trying so hard to be right, and read about the actual problem. You're being a jerk for no good reason, which makes anything accurate you might spew fade right into the rest of the verbal diarrhea.
