GPU drivers issue

[undercooked spaghetti]

Hi, i have observed that my GPU (MSI GTX 1070) is not being utilized 99% in games like it used to be before. Maybe this happened after driver updates? I'm not sure. In games like GTA, i was getting 40%-50% GPU utilization and terrible framerates. I tried DDU and re-installing the latest drivers, Performing a clean install from Geforce Experience and reinstalling by using express installation. Even in my Geforce Control Panel, my power settings are at "Prefer maximum performance". After performing a clean install and then doing an express install again (this works on my PC for some reason), my GPU utilization got much better but still not at 99% like it was before. Also, i have noticed that whenever i enter graphic intensive areas in any game, like cities in RDR2, my GPU utilization starts decreasing. Also,  If i disable my iGPU from the device manager or the BIOS, my Dedicated GPU utilization drops by huge numbers. My iGPU is enabled but still my Dedicated GPU is suffering. Whenever i start my adobe after effects, it says "Outdated driver for intel HD 4600". Should i update my iGPU driver? maybe that will fix the utilization problem? will that collide with my Dedicated GPU drivers? Any help will be appreciated.

Is your cpu now running full out while you gpu is no longer doing so?  Is this a different game than you were running when you were getting full out usage of your gpu?
