CPU usage spiking in games - 90% - 100%(Game taking all the CPU in task manager)

[Arvind]

Specs:
Rtx 3070 Aorus Master
Ryzen 5 5600x
16 gb ram - 2133 mhz (also tried xmp at 3200)
nvme ssd
gigabyte aorus b450
silverstone 750w gold

I recently posted a question on the forum (GPU usage fluctuation problem) but i thought the issue was my old R5 2600 which might be causing some bottleneck.
But today i received a new R5 5600x.. Now the GPU usage seem stable but it is the CPU usage that is now spiking.
Another issue is the GPU usage is below 75% sometimes in games at 2k resolution. Again i thought this was happening because of the 2600.. but still persists after upgrade(5600x).. Only 4k resolution pushing the card to 99% but problem is CPU usage also getting too high..
All these are leading to Fps drops and stutters when the CPU usage is getting too high..(happens at moments like if lots of things going on like if many NPC present or in a big town.. and also when fighting or if lots of particles present like blood etc.. )
The issue arises at particular scenes in games or sometimes just randomly..
One more thing i want to mention is that i am facing LOD issues as well(very poor draw)

I tested games like: Resident evil village, Monster hunter world, Red dead redemption 2, Dishonored 2, Dying light 2, Steel rising, resident evil 2

Cpu usage when idle is really low at below 10%
Only gaming pushing it to 90-100% and it is the game itself thats taking all the usage in task manager.

From my past forum post i tried lots of things like:
Tried xmp at 2800 and 3200mhz, also tried different sticks of Ram, optimized Nvidia control panel towards performance and then towards Quality, Fresh Install Windows and Nvidia drivers using DDU, Reset Bios to default, Reseated GPU and Ram, changed DP cable, Run games at Max quality then Max performance then optimized(none worked), Bios and Chipset Update.

Your CPU has to do a lot of calculating to make a game work, games like RE, RDR2, etc are very physics heavy, so it's normal that lots of particle effects, or even calculating how NPC's clothing works in the world would be taxing at some times more than others.

If you want to test, try bringing your settings down, this will bring your CPU usage down, perhaps try using NVidia GeForce Experience to optimize your game settings.

If that doesn't seem to affect the issue, which I think it should, follow the steps below:

Download and run speccy.

Once you have ran speccy, follow the instructions to upload a snapshot found here.

To publish a Speccy profile to the Web:​

1. In Speccy, click File, and then click Publish Snapshot.
2. In the Publish Snapshot dialog box, click Yes to enable Speccy to proceed.
3. Speccy publishes the profile and displays a second Publish Snapshot dialog box. You can open the URL in your default browser, copy it to the clipboard, or close the dialog box.
