Microsoft revealed DirectX Raytracing 1.2 at the Game Developers Conference 2025. They fixed two major ray tracing problems and created opacity microamps that save pre-made opacity data. This reduces work when rays pass through see-through objects.
They also introduced shader execution reordering, which groups similar tasks for better graphics card performance. These fixes speed up games beyond what Microsoft claims as 2.3 times and 2 times faster. They mark a change from raw power to smarter resource use. Both features need special hardware support.
NVIDIA announced their RTX cards work with these features, but nobody knows when other companies will support them. Microsoft also launched Shader Model 6.9 with cooperative vectors. This makes matrix math ten times faster and uses 75% less memory than before. It connects regular rendering with neural rendering.
Intel, AMD, and NVIDIA already show this by combining path tracing with neural noise cleanup. This might bring high-end graphics to regular computers by late 2025. The preview toolkit launches in April 2025, but developers need months before these features show up in actual games. They represent a major leap for ray tracing on everyday computers.
