So, I only have problems with direct games 11-12. The videocard works great on the desktop with any program. But artifacts appear during games running with Directx 11 or 12. Games with Vulkan run better, but minor bugs appear over long sessions. I tested the video card in my friend's computer and he has the same problem. The video card is in stock and without overclocking.
My system:
Cpu: AMD FX-8300 3.3 MHz
MB: Asus M5A78L-M LX
GPU: Sapphire Nitro+ RX 470 4GB
RAM: Kingston 8+4 GB DDR3 800 MHz
Radeon driver version: 21.2.3
What do I need to do about this problem? Help PLZ.
