Qualcomm's latest Snapdragon X2 Elite Extreme was supposed to be the chip that finally made Windows on Arm a serious contender in the laptop market, particularly for gaming. Yet a recent test of the fan-made remaster Halo: Campaign Evolved on this hardware paints a far less optimistic picture. The headline, delivered with a sigh, was "It's not great news," and the benchmarks and hands-on observations back that up. While the processor demonstrates impressive raw potential in productivity workloads, its gaming performance continues to reveal just how far the Windows on Arm ecosystem still has to go.
What is Halo: Campaign Evolved?
Halo: Campaign Evolved is not an official release from 343 Industries or Xbox Game Studios. It is a fan-made mod for Halo: Combat Evolved, originally released in 2001 for the original Xbox. The mod aims to bring the classic campaign closer to the visual and mechanical standards of later entries in the series, with enhanced lighting, reworked textures, improved audio, and subtle gameplay adjustments. It has become a beloved project within the modding community, often used as a benchmark for how well older games can be modernized without a full remake.
Because the mod is built on top of the original PC release of Halo: Combat Evolved, it runs on the same engine that was designed for Windows XP-era x86 processors. That makes it an interesting test case for Windows on Arm, as it requires either native Arm support or efficient emulation. At present, almost no x86 Windows game runs natively on Snapdragon processors, so the experience depends heavily on the compatibility layer known as Prism, which Microsoft introduced to translate x86 and x64 instructions to Arm64. The results from this test suggest Prism still has significant limitations when dealing with even moderately complex 3D games.
The Snapdragon X2 Elite Extreme at a glance
The Snapdragon X2 Elite Extreme is Qualcomm's next-generation Arm-based system-on-chip, designed to compete directly with Intel's Core Ultra and AMD's Ryzen AI processors. It features even more powerful custom Oryon CPU cores, an upgraded Adreno GPU, and an enhanced neural processing unit for AI workloads. Qualcomm has boasted about large generational gains in multi-threaded performance and energy efficiency, positioning the chip as a legitimate alternative for premium ultrabooks and even some lightweight gaming laptops. Early synthetic benchmarks did show substantial improvements over the previous Snapdragon X Elite, and many reviewers praised the chip's ability to handle code compilation, video editing, and other native Arm64 applications with remarkable speed.
However, the real test for any Windows laptop is its ability to run the vast library of x86 software that most consumers still rely on. In the case of the X2 Elite Extreme, the focus on gaming has been particularly aggressive. Qualcomm has partnered with several PC manufacturers to release gaming-focused models, and the company has claimed that the combination of the new Adreno GPU and Prism emulation can deliver playable frame rates in many popular titles. But those claims, like this recent Halo test, often come with caveats about compatibility, graphical glitches, and inconsistent performance.
How the test was conducted
The test used a reference laptop equipped with the Snapdragon X2 Elite Extreme, paired with 32GB of LPDDR5X memory and a fast NVMe SSD. Halo: Campaign Evolved was installed from old-school disc images and mod files, and the game was run at 1080p resolution with the mod's recommended settings. No external GPU was used; the system relied entirely on the integrated Adreno graphics. The testing process involved both a benchmark sequence of the first level, "The Pillar of Autumn," and extended gameplay in open sandbox areas to check for thermal throttling and frame pacing issues.
According to the testers, the first hurdle appeared during installation. The game's launcher, which was written for x86 Windows 7-era systems, triggered the Prism emulation layer but took an unusually long time to initialize. Once inside the main menu, the frame rate was surprisingly stable, hovering around 60 frames per second. But as soon as the actual campaign loaded, the performance collapsed. In cutscenes with dynamic lighting and several in-game characters on screen, the frame rate dipped to the low 20s. During combat sequences with multiple enemies, explosive effects, and AI-driven allies, the stuttering became severe enough to make the game nearly unplayable.
Frame drops and shader compilation stutter
The most common issue observed was shader compilation stutter. In modern PC games, shaders are typically compiled before a level loads, or at least cached after the first encounter. On the Snapdragon X2 Elite Extreme, the Prism emulation layer seemed to struggle with the game's proprietary DirectX 9-era rendering pipeline. Every time a new visual effect appeared, such as a plasma bolt, a reflective surface, or a shadowed doorway, the game would freeze for a fraction of a second while the GPU compiled the necessary shaders. This is a familiar problem on Windows on Arm devices, but the frequency and severity here were notable even compared to previous Snapdragon X Elite results.
The testers noted that the game's CPU-bound sections, such as when large groups of enemies were active, also hit a wall. The Oryon cores are capable of high integer scores in benchmarks, but the translation overhead from x86 to Arm64 reduces the effective instructions per clock. As a result, the game's AI logic and physics calculations, which were originally written for x86 processors, became a bottleneck. In the "Halo" universe, where combat encounters are dynamic and enemies coordinate attacks, this led to noticeable slowdowns and even brief freezes when the action became too intense.
Additionally, the integrated Adreno GPU often proved to be a limiting factor. While Adreno has improved significantly in raw throughput, its driver support for legacy DirectX features remains spotty. Halo: Combat Evolved uses DirectX 9 and relies on fixed-function blending and stencil buffer effects. Under Prism, these features are translated to Vulkan or DirectX 12 calls, and the translation is not always efficient. The result is that the GPU spends more time on overhead than on actual rendering, leading to underutilization of both the CPU and GPU despite poor frame rates.
Comparing to Apple Silicon and native x86 laptops
To put the results in context, the same mod was also tested on an Apple MacBook Pro with an M4 Pro chip running the game through a similar emulation layer, using Microsoft's recommended setup for cross-platform testing. The M4 Pro delivered nearly double the average frame rate in the same sequence, with fewer shader compilation hitches. While Apple's hardware is certainly competitive, the gap is also indicative of Prism's maturity. Apple introduced its own translation layer, Rosetta 2, in 2020, and it has had several years of refinement. Microsoft's Prism is still relatively new, and it has yet to match the consistency of Apple's solution. Moreover, Apple's MacBooks are not even marketed as gaming machines, yet they often outperform Windows on Arm devices in this particular type of workload, which is a damning observation for Qualcomm and Microsoft.
The test also included a comparison with a budget x86 gaming laptop featuring an Intel Core i5-13500H and an NVIDIA GeForce RTX 3050. That system ran the same mod at 1080p with no emulation layer, achieving a locked 60 frames per second with occasional dips to 50 during intense scenes. The x86 laptop did not require any shader compilation workarounds, and the entire experience felt smooth from start to finish. It is important to note that the Core i5 laptop is not a performance powerhouse by modern standards, but it thoroughly trounced the much more expensive Snapdragon X2 Elite Extreme in this gaming test. This highlights the fundamental challenge facing Windows on Arm: even the best translation layer cannot fully replace native instruction set compatibility.
More than just raw performance: compatibility issues
Performance numbers are only part of the story. The testers encountered a range of compatibility issues that would be deal-breakers for the average gamer. The game's anti-cheat and DRM components, though relatively primitive, refused to run correctly under Prism. One such component caused the game to crash to the desktop whenever it attempted to verify the original disc's copy protection. The workaround involved downloading a compatibility patch from a fan forum, which is not a realistic expectation for most players.
Audio also proved problematic. The game's EAX-based sound effects, which rely on 3D audio positioning, did not translate well through the Arm64 layer. Sounds occasionally dropped out or were played in the wrong location, breaking the immersive experience. Visual glitches were also frequent, including missing textures on transparent objects and flickering shadows. These issues are often attributed to driver bugs, but they are also a consequence of the layered approach to emulation. When a game makes a system call that the translator does not recognize, the behavior becomes unpredictable. In some cases, the game simply ignores the call, which causes subtle artifacts. In others, the game crashes outright.
The testers also noted that the Snapdragon X2 Elite Extreme's power management interfered with gaming performance. Windows on Arm is designed to prioritize battery life, so the scheduler frequently moves threads between the high-performance and high-efficiency cores. This is excellent for web browsing and productivity, but it causes severe frame rate instability in games. The chip's frequency ramps up and down too aggressively, leading to hitching and micro-stutters. While a gaming mode exists that can lock the CPU to its highest frequency, it consumes a significant amount of power and causes the laptop's fans to become obnoxiously loud. Even then, the frame rate remained inconsistent, suggesting that the hardware scheduler itself is not optimized for low-latency game workloads.
What this means for the future of Windows on Arm gaming
Microsoft and Qualcomm have repeatedly assured consumers that Windows on Arm is ready for prime time, and the Snapdragon X2 Elite Extreme represents another step forward. In many ways, it is a remarkable piece of silicon. The CPU performance is exceptional for multi-threaded tasks, and the energy efficiency is class-leading. Yet gaming is an unforgiving test because it requires the entire software stack to work in perfect harmony: the operating system, the CPU, the GPU, the drivers, and the emulation layer. Any weakness in one area can tank the overall experience. This latest test of Halo: Campaign Evolved exposes weaknesses in all of these areas.
One could argue that Halo: Combat Evolved is a 2001-era game that should run flawlessly on any modern hardware, regardless of architecture. The fact that it does not is a clear sign that Windows on Arm still cannot replace a traditional x86 gaming laptop for the vast majority of players. Even the most popular esports titles, such as Fortnite or Valorant, have been shown to experience similar issues on Arm-based laptops. The situation is improving with each generation, but the pace of change is agonizingly slow. Qualcomm's new Oryon cores and the upgraded Adreno GPU are impressive on paper, but the software ecosystem is not keeping up with the hardware.
The positives should also be acknowledged. The Snapdragon X2 Elite Extreme can run many older or less demanding games at acceptable frame rates, and some newer titles with native Arm64 ports, such as Baldur's Gate 3 and Minecraft, perform remarkably well. The Prism emulation layer is also steadily improving, and Microsoft has made a strategic push to support more game anti-cheat systems through a new framework. But the reality is that most gamers do not play only modern titles; they play a backlog of older games. A system that struggles with a beloved classic like Halo: Combat Evolved will not win over enthusiasts. Instead, it will become a niche product for those who value portability and battery life far above gaming fidelity.
The testers concluded that while the Snapdragon X2 Elite Extreme is an impressive piece of engineering, it is not yet a viable solution for serious gaming on Windows. The chip's promise remains unfulfilled until Microsoft can deliver a translation layer that reliably handles low-level graphics APIs and until Qualcomm's graphics drivers meet the stability standards of AMD and Nvidia. For the moment, the phrase "It's not great news" is an apt summary, but it is not the final verdict. The progress from the original Snapdragon X Elite to the X2 Elite Extreme is measurable, and it is possible that a few more driver updates and Windows patches could close much of the gap. But until that day arrives, Windows on Arm will remain a curiosity for gamers rather than a true alternative, and Halo: Campaign Evolved will continue to serve as a humbling reminder of the road ahead. That may not be the most exciting prospect, but it is the honest reality based on the current evidence. The silicon is ready, but the ecosystem is still catching up, and as this test shows, the journey is far from over.
