Microsoft has revealed impressive results after implementing its DirectX Shader Execution Reordering (SER) technology. According to recent tests, this feature has boosted the performance of Intel’s “Battlemage” GPUs by up to 90%, marking a major step forward in handling complex graphics workloads.
What Is SER and Why Does It Matter?
In traditional graphics rendering, especially when Ray Tracing is used, performance bottlenecks can happen because tasks are processed in an unorganized way. When a ray hits different objects with different materials, the GPU must handle multiple shaders at the same time. This can leave some cores idle while waiting for others to finish.
Shader Execution Reordering solves this problem by reorganizing tasks in real time. By grouping similar workloads together, the GPU can work in a more efficient and smooth way. Microsoft has included this feature in Shader Model 6.9, making it available to developers through the Agility SDK.
Performance tests have shown very interesting results. Intel’s B-series GPUs based on the Battlemage architecture nearly doubled their frame rates in some cases. Other graphics cards, such as the Nvidia GeForce RTX 4090, also showed strong improvements of around 40%.
It is important to note that these numbers come from controlled test environments, so real-world gains in games may be lower. However, the improvement comes through software, meaning it is essentially a free performance boost.
As graphics architectures become more powerful and games more demanding, technologies like SER will become essential to maintain strong performance. Just like DLSS and Frame Generation, SER could play a key role in the future of gaming performance.
