Good specs, high fps still lag and frame skip

If anyone can help me please do. So I have this Asus G16 with i7-13650HX, RTX 4060 and 16GB of RAM. Any game that I try to play has good fps but micro stuttering and freezes. First I tried Cyberpunk of many different settings Medium to low till potato PC settings nothing worked .Then I tried God of War Ragnarok same problem. Then I tried GTA4 and nothing works. I'll list a few things that I read on other subreddits and YT Videos nothing has worked till now. Till now I have - •Updated all the windows and drivers including audio drivers. •Disabled unnecessary audio devices (Because Cyberpunk also had choppy audio along with lag) •Frame-rate Cap at 60 in RIVA tuner •Low settings in game •Windows power settings to performance •Disabled all the E-Cores. •Compete reinstall of windows and downloading everything again •Updated every Driver and BIOs I get that old games can be tricky running on modern display mine is 165hz. But modern games shouldn't do it. This video is from Gta4 where the graph shows each lag. When I got this laptop 3 or 4 months ago it played anything at 1080p high settings idk what had changed now. So fat I have tested Forza 5 , Gta4 , GoW ragnarok, Ghost recon Wildlands. Some Hot wheels game.

I wanted to see if the GPU was getting utilized properly. So, the game was running in the BG and I was looking at task manger the GPU was working fine. EVEN THE GAME RUNNING IN THE BACKGROUND MADE ME SKIP FRAMES JUST USING THE BROWSER. It was lagging the same way after intervals a part scroll will be skipped. I think something has to do with my display drivers selection between Intel and switching to Nvidia as it blocks me from changing my brightness(just a guess). Please help
