Fortnite Runs Smoothly on Windows on Arm, Signaling Gaming Readiness

Fortnite can now be played directly on Windows powered by Arm64 chips, including the Snapdragon X Plus, X Elite, and the anticipated X Elite 2. This development marks a significant step forward for mobile gaming enthusiasts using Arm architecture.

In August, Epic Games announced an upgrade to its “EOS” (Epic Online Services) SDK, which gained support for ARM64 on Windows platforms. This enhancement ensures compatibility of Easy Anti-Cheat, the kernel-level anti-cheat software, with ARM64 devices.

Despite this substantial update, Fortnite itself did not initially support this functionality, leaving players unable to launch the game on Arm devices. In contrast, other titles, such as VRChat, quickly integrated the updated SDK, granting access to ARM users.

The landscape changed on November 1st, during the rollout of Fortnite’s version 38.00 update, where a significant but undocumented change was noted: the inclusion of the EOS SDK version along with Easy Anti-Cheat support for ARM devices as highlighted by Windows Latest.

Experience Fortnite on Arm-Based PCs with Impressive Performance

I took the opportunity to test Fortnite on my Arm PC and was pleasantly surprised by its performance. Running at default “performance” settings with v-sync activated, I maintained a stable 60 FPS with minimal hitches.

However, occasional lag occurred during texture streaming in the initial matches. Given that Qualcomm has previously indicated that the Snapdragon X platform is not primarily designed for gaming, it’s encouraging to see that developers are making strides to enhance compatibility with these devices, thereby increasing their overall functionality.

This improvement allows players to enjoy extended battery life while also engaging in light gaming, effectively transforming these devices into versatile tools for both work and play.

With industry leaders like Epic adapting their anti-cheat systems for ARM, it’s hopeful that other developers, such as Riot Games with their Vanguard system, will follow suit.

Prism Emulator Enhancements for Windows on Arm

The recent advancements in Fortnite’s compatibility on Arm64 are not the only noteworthy updates. Microsoft has also confirmed enhancements to Prism, the emulator for Windows on Arm. The emulator has been updated to leverage new CPU features, allowing more 64-bit x86 applications to run via emulation with improved performance.

The recent October 2025 Update (KB5066835) was observed to elevate Prism’s capabilities, specifically supporting AVX/AVX2 technology. AVX (Advanced Vector Extensions) consists of mathematical instructions enabling applications to process substantial data sets simultaneously, which is vital for many gaming and creative applications typically dependent on Intel or AMD architecture.

As most ARM chipsets lack native AVX support, many applications faced operational hurdles. However, with AVX now emulatable, a wider range of software can successfully run on devices powered by Snapdragon X chips, though performance may still vary due to the limitations of emulation.

To enable this feature, simply access an application’s.exe file, right-click, then go to Properties > Compatibility > Windows Arm compatibility and select “Show newer emulated CPU features.”
