Windows 10: Why does my cpu and gpu keep spiking and dropping fps in games?

My CPU keeps spiking to %100 and then my GPU to %20, then my game keeps dropping fps and the spikes are crazy.

:)

 

Why does my cpu usage spike and my gpu usage drop during gaming?

My pc specs are

CPU - Intel(R) Core(TM) i7.10700F 2.90 GHz

GPU - NVIDIA GeForce RTX 2060

RAM - 2x16GB

My problem is while gaming my fps drops at the same times at the CPU usage spikes to 80%-90% and my GPU usage drops to 20%-30%. I've just completely reset my pc in hopes that some program had corrupted it. but it didn't help. Also to say. My settings in the games are set to low/medium.

Please ask if you need any more information. But I don't know what to do.

Massive FPS Lag And GPU Spikes

I've recently noticed that when running games like Minecraft and League of Legends, the FPS stutters and drops suddenly. This problem only started a few weeks ago - before that it ran fine. I usually average around 90FPS in Minecraft and 70FPS in League, but during the spikes it drops to 5-10FPS. The spikes used to only occur every few seconds and went away after a while, but now they're frequent and make trying to play near impossible.

I opened up Task Manager when running Minecraft, and the GPU constantly spikes from around 30% to up to 90%, causing the drops. Most of the GPU usage is from Java running, and the spikes are from it as well. Running on Windows 10, I already have Optifine installed on Minecraft. The problem only occurs in fullscreen.

Things I've already tried:

• Uninstall and reinstall graphics drivers
  
• Cleaned out junk files
  
• Uninstall and reinstall games
  
• Close background programs, end tasks in Task Manager
  
• Ran multiple antivirus scans using AVG, MalwareBytes and Adaware(no problems found)

CPU and GPU usage high, fps drop on games

Hi. I usually have around 100fps at Player Unknown Battlegrounds and my CPU usage is normal. From a month or so I get fps drops like 50-100fps and game feels laggy.

Also, when I open the task manager the CPU and GPU usage is really high around 90, 80% and then suddently drops to normal values like 5%.

I checked igfxupdate.exe Windows process - What is it? but it doesn't resolve it.

I noticed that a service svhost is very high on usage, what can I do?

Thanks in advance.
