Nvidia graphics driver Bug, DX12 game performance is not as good as AMD entry-level graphics

Hardwareunboxed reported that NVIDIA's graphics driver had a bug this month, and the performance of DirectX 12 games, which rely heavily on CPU, will decline significantly.


Hub said that the reason for the problem may be due to NVIDIA's optimization function for the graphics card. These optimizations performed well in Dx11 games, and the performance of the graphics card surpassed that of AMD's products of the same level. But when it comes to dx12, NVIDIA will lag behind.
In the dx12 game which depends heavily on CPU, the performance of NVIDIA's graphics card drops seriously. According to foreign media, in the case of using older CPU (such as i7-4790k), the performance of RTX 3080 is even worse than that of AMD RX 5600 XT, whose normal performance is only equivalent to that of RTX 2060. The performance of NVIDIA's RTX 3080 graphics card will be fully developed when AMD r55600x CPU is used. In addition, if equipped with a CPU below i5-9400f, the performance of the graphics card can not even be significantly different from that of the RX 5600 XT.
At present, NVIDIA has not announced to solve this problem, but this series of tests also show that the CPU performance requirements of today's 3D blockbusters, quad core processors can no longer meet the mainstream games, and the game performance of both AMD and Intel's graphics cards on faster processors has been significantly improved.
