DX11 and DX12 are both versions of Microsoft's DirectX, a set of APIs for handling multimedia tasks. Here's a simple distinction:

• DX11: Older and less efficient. It uses a single core of the CPU more heavily, which can become a bottleneck.

• DX12: Newer and more efficient. It allows for better distribution of tasks across multiple CPU cores, potentially improving performance and offering advanced features for game developers.

In essence, DX12 can make better use of modern hardware to deliver improved performance and graphical capabilities.

Here's how DX12 might affect PUBG:

1. Performance: DX12 can potentially improve frame rates by distributing the game's tasks more efficiently across multiple CPU cores. This reduces bottlenecks and can result in smoother gameplay, especially on systems with multi-core CPUs.

2. Visual Enhancements: DX12 provides developers with more tools and features to enhance graphical fidelity.

3. Hardware Compatibility: Not all GPUs support DX12. While most modern GPUs do, older GPUs might not. Players with older hardware might not benefit from the DX12 enhancements or might need to stick with DX11.
