DirectX 12

High-end GPU systems experience persistent frame drops and stuttering in demanding DirectX 12 games like Cyberpunk 2077 and Starfield, despite having sufficient hardware resources.

The industry is experiencing a memory shortage making high-VRAM GPUs increasingly unaffordable. Additionally, DirectX Raytracing requires significant VRAM for acceleration structures, forcing developers to implement complex workarounds like Sampler Feedback to manage memory constraints.

Ray tracing implementation is inconsistent within Nvidia's Pascal and Turing GPU architectures, creating uncertainty when developing games targeting variable hardware configurations and forcing developers to handle feature parity issues.

Variable Rate Shading (VRS) produces poor results when combined with upscaling techniques and requires significant implementation complexity. Some upscalers will not produce good results when used together with VRS, forcing developers to disable VRS when using upscaling or sharpening filters.
