Windows 10: fps drop when minecraft is fullscreen

so I've been having a problem, when I turn on fullscreen or make the windowed minecraft bigger the fps drops, and when the window is smaller the fps increases. What do I have to do to fix this?. This started when I updated windows after it having been corrupted and recovered, before that everything was fine. This only happens in minecraft, nowhere else.

FPS drops when playing Minecraft in Full screen

Yesterday I updated my driver. Everything was fine, like Youtube and other apps, but whenever I try to open Minecraft in Fullscreen, my Fps drop to 2-10, and if I switch to windowed everything works properly.

I have a «GeForce GTX 1060 6Gb» graphics card.

Sudden FPS drop/Stutter

Since 2 days ago, I just turned on my Computer, and it starting having issues while I was playing Witcher 3 (starts with decent fpsm and then very low fps, dropping to 35, then 20, and stopping at 12 or so, in a matter of seconds, in a matter of 1min of starting the game), also stuttering without any high demanding programs, randomly. I was playing at 45-60 fps, without any stutters or sudden fps drop. Have tried other games the issue persists. Even setup everything to low settings.
I have ran several tests with several tools, all seems normal, no sudden memory spikes, or temperature raising out of the ordinary, nothing that would indicate such an fps drop or stuttering.

MSI Afterburner

I also did the reset option on Windows10, completly cleaned out all my personal info from the windows partition.
So at this point, I am not sure if it is a software issue or a hardware issue.
Any suggestions are greatly appreciated.

Edit: I kept doing some tests to find out the issue. And this happened before and I was able to replicate it. Same thing happened as before, till I set it up to fullscreen, Alt+Tab from the game and then back to the game, FPS went up to 50 again, stable and good, dropped after a couple of seconds. After a bit it went to 2-5 fps, and I had to shutdown the game, because even the sound was getting messed up.

MSI Afterburner 2

In this image those ups and downs in the GPU usage are when the fps dropped really hard and the sound got messed up.

 

FPS drops when playing Minecraft in Full screen

Hi,



Thank you for writing to Microsoft Community Forums.



In order to help you with the appropriate troubleshooting steps, please reply with the following details:

• Does this issue occur only while playing Minecraft?
  
• Which build version of Windows 10 is installed on the computer? To check type:
  winver in the search bar on the Taskbar and hit
  Enter.
  

As you have mentioned that this issue occurs in Minecraft, and if you have downloaded Minecraft from store, I suggest you to refer the troubleshooting steps in the article

Fix problems with apps from Microsoft Store and see if that helps.



You can also refer the troubleshooting steps mentioned below:



Method 1: Clean boot



This could be due to background apps or services taking more resources on the computer that is why you get FPS drop. We can try performing a clean boot on the computer and check if that helps in resolving the issue.



Performing a clean boot will start the computer with minimal set of drivers and programs, to determine whether a background program is causing the issue. Some of the Startup programs will not load after performing a clean boot on the computer. However,
that functionality will return when you reset the computer to start normally after finishing the troubleshooting.



To perform a clean boot on the computer refer to the article How to perform a
clean boot in Windows.



If performing a clean boot fixes the issue then, please refer to the section
How to determine what is causing the problem after you do a clean boot
to check which program is causing the issue.



Note: Please refer the section Reset the computer to start normally after clean boot troubleshooting
to boot the computer in to normal mode after troubleshooting.



Method 2: Rolling back driver



As you have mentioned that after updating the drivers you are facing this issue, I suggest you to try rolling back the driver. Please refer the steps mentioned below:

1. Press Windows key + X, and select
   Device Manager.
   
2. Expand Display adapters.
   
3. Right click on the NVidia Driver and select
   Properties.
   
4. Navigate to the Driver tab and click on
   Roll Back Driver.
   
5. Restart the computer if prompted.
   

Please reply with the status of the issue, we will be glad to help you further.
