Windows 10: Games run slow unless I force directx12

My pc suddenly has problems running a lot of games, while it's specs are quite high.It used to be able to run almost any game, but it currently has issues running any game I try.It has no issues outside of running games, other things work just fine.The games run at about ~15 fps, while I should be easily able to run them.I have been able to fix 2 games using steam flagsead by Daylight by using the -dx12 flagRimworld by using the -force-d3d12So both of these flags force the game to run using directx12, but I have no idea why this works. I would force every game to run in directx12 if I could,

DirectX12 compatible with DirectX11 games (Fortnite)?

I recently downloaded Fortnite, but cannot launch it. Whenever I try to launch it, it says that the engine requires DirectX11. I checked my DirectX and it says that I have DirectX12. A lot of threads say that Fortnite runs on DirectX12, too. Can Fortnite
run on DirectX12? If not, can I switch to DirectX11? I also have a bad feeling that it's my GPU. I currently have integrated Intel UHD graphics.

 

Wanting to run old games

Hi Jameson,

Welcome to Microsoft Community. Your interest in Windows 10 is much appreciated.

I would suggest you to refer the below link and check the compatibility of the game with Windows 10.

http://www.microsoft.com/en-us/windows/compatibility/CompatCenter/Home

You may also try installing the game in compatibility mode.
Follow these steps to install the game software in compatibility mode and check if that helps.

• • • • 
        Right-click on the game setup file and click on
        ‘properties’.
        
      • 
        Click on the ‘compatibility’ tab and check the box
        ‘Run this program in compatibility mode for’ and select Windows 8 operating system from the drop down menu and proceed with the installation. Once this is done, restart the computer and check if the issue persists.
        

If the issue still persists, I would suggest you to get in touch with the game manufacturer if it’s specific to that particular game.

Keep us posted if you face any issues on windows in future. We will be glad to help you.

 

What's the problem with Directx12?

Hi Microsoft. I have dire question that needs addressing.

"What's the problem with Microsoft Directx 12 API as far as compatibility issues?"

Directx12 as we know has been around 5 years since the release of Microsoft 10. No matter what graphics card is used or what configurations are set, when Directx12 API is loaded, regardless of what type of game is played, it always crashes. Frozen screen.

Over the years, there have been countless gaming forums on the internet of thousands of gamers having the same issue; no one has ever gotten Directx12 to work in any game successful ever.

With a 2080 TI, I can't even enable raytracing without Directx12 in Control by 505 games. Like everyone else, with Directx12, the issue has gone on for years.

So my question is:

1.why is why is Directx12 offered in games if no one can use it?

2. Does Microsoft have any knowledge of this issue?

I will send this message to NVIDIA as well. I want to get to the bottom of this. Thank you for reading and understanding the issue. Please respond whenever possible.
