3DMark adds native Windows on Arm support for ray-tracing benchmarks

With NVIDIA's new RTX Spark chip for laptops pairing an Arm-based 'Grace' processor with RTX Blackwell graphics, the first wave of ultra-thin, premium laptops sporting the chip is expected to debut later this year. At Computex 2026, we got to go hands-on with a number of them and even see games like Alan Wake 2, Fortnite, Indiana Jones and the Great Circle, Pragmata, and more running and looking good.

And based on our discussions with both NVIDIA and Microsoft representatives at the show, these new Windows on Arm devices powered by RTX Spark are set to usher in a new era for the specialized version of Windows, with more native app support and better-optimized emulation. And with that, we'll probably start to hear a lot more about Windows on Arm updates and support in the lead-up to the RTX Spark launch.

Case in point, today we've got word from UL Solutions, the makers of the popular 3DMark benchmark suite for measuring PC gaming performance. The company has confirmed that it's updating more of its synthetic benchmarks with native Windows on Arm versions.

This includes the popular ray-tracing benchmarks, Speed Way and Port Royal. It also includes some of the feature set and more technical benchmarks, such as the Mesh Shader feature test, Sampler Feedback feature test, DirectX Raytracing feature test, PCI Express feature test, and VRS feature test. And the good news is that you'll be able to toggle between native Arm versions of these benchmarks and the x86/64 emulation versions to gauge any notable differences in performance and/or image fidelity.
