Background: I have a Nitro 5 laptop which I use only to play a few STEAM games. It has been flawless for a year with no significant issues. The only time I have experienced lagging in a game is when I haven't had the power cable connected.
Suddenly, game started lagging and they are now unplayable.
I have tried/done the following, with no success:
*Re-set laptop multiple times.
*Ensured I am running latest NVIDEA graphics driver and Windows 11
*Ensured high performance options are selected in terms of battery plan and via NVIDEA control panel etc.
*Reinstalled STEAM and relevant games multiple times.
*Checked integrity of game files
*Disabled any background processes that might be causing low FPS
*Cleaned fans although cooling doesn't seem to be an issue.
*Defragmented disc drives etc.
*Checked for bugs
