Red Dead Redemption 2 DX12 API poor performance and Shadows and anti-aliasing issues

[Jamas94]

Does your system meet the game’s minimum system requirements?

Yes

Did you already installed the Intel Graphics Driver latest release found at Intel® Graphics – Windows* DCH Drivers?

Yes

Please provide your system information by attaching the following file:

1.      Download the System Support Utility tool to the system where the issue occurred.

2.      Run SSU.exe. Select "Everything". Then click Scan.

3.      Save the data to the text file and attach it to this report.

Report.txt

Please describe your issue as accurately as possible.

The performance under DX12 API is half less than that of Vulkan API, and the number of frames will be locked at 37 frames strangely. In addition to time anti-aliasing, DX12 and Vulkan think that if other anti-aliasing is turned on or FSR is enabled, shadows will flicker across the screen.
Regardless of whether the anti-aliasing option is turned on, squares will appear on the edge of shadows at close distances, such as notebooks and other close-up shadows, and shadows in games such as those under lights will appear incorrect shadows.
In addition, the application performance tuning settings in the Arc control center will show that the fan will not exceed 1200 rpm. The fan curve will not exceed 1200 rpm under high load until the system is restarted and the Arc control center restores the default configuration.

This probability is 100% recurring

Hello @Jamas94

Thank you for posting on the Intel communities. We are sorry to hear that you are having issues with your system, we will do our best to help you.  

In order to have a better understanding of the issue, please share with us the following information:  

• When did the issue start? Were there any recent changes?  
• Is Resizable Bar enabled in the BIOS?

Resizable Bar it is enabled 

No any other graphics card installed previously

This graphics card will play games with a black screen and restart the system under certain circumstances, especially for heavy-loaded games or games that are not optimized. It does not have any system events or error messages, and the system will only record an event that it did not shut down normally.
It's not just me
