PC gaming on Android has undergone a remarkable transformation since the introduction of applications like Winlator a few years back. The landscape has evolved to a point where playing older, yet demanding titles on mobile devices is no longer a distant dream, especially when considering the advancements made in recent times.
Emergence of GameNative and Turnip Drivers
Among the notable developments is the rise of GameNative, which has quickly established itself as one of the most refined and capable PC emulators available on Android. Additionally, the introduction of custom Turnip GPU drivers for Qualcomm’s Snapdragon 8 Elite chips has significantly enhanced gaming performance. Previously, devices equipped with Snapdragon 8 Gen 3 chips and earlier were deemed more suitable for PC gaming, but this shift has opened new avenues for mobile gaming enthusiasts.
Curiosity piqued by these advancements, I pondered whether Samsung’s latest flagship Galaxy phones, powered by the Snapdragon 8 Elite family, could provide a lightweight gaming PC experience when connected to an external monitor. While I didn’t expect to dive into the latest AAA titles, I wondered if this setup could serve as a viable alternative to my work laptop after hours.
Exploring Game Compatibility
Equipped with a Samsung Galaxy S25 Ultra and an old Jsaux dock typically used for handheld consoles, I set out to explore various PC games using the GameNative app, which boasts integrated Steam support. My approach involved switching between the system GPU driver and the community-driven Turnip drivers to assess any noticeable differences in performance and thermal management.
Starting with lightweight 2D games, I found titles like Baba is You, Mina the Hollower, and Battleblock Theater running smoothly, regardless of the GPU driver in use. The temperatures remained manageable, although not every lightweight game performed flawlessly; for instance, Call of Duty 2 encountered a Steam-related error that prevented it from launching.
Transitioning to 3D titles from the late 2000s to early 2010s yielded some unexpected results. Crysis performed admirably at 1080p with low graphics settings, despite some noticeable judder during intense firefights. While temperatures peaked around 68 to 70 degrees Celsius, the phone did not feel excessively hot. Similarly, Tetris Effect delivered smooth gameplay, and Deus Ex: Human Revolution maintained a respectable frame rate, albeit with occasional dips.
As I delved deeper, I tested Metal Gear Solid V: The Phantom Pain, which initially took longer to boot than expected, leading me to believe the game had frozen. However, using the Turnip driver resulted in a stable performance, consistently hovering around the 60fps mark, though temperatures did reach the low 70s. Dishonored also ran smoothly, reinforcing the notion that recent Android flagships can handle older or less demanding PC games effectively.
Testing Demanding Titles
My exploration continued with The Witcher 3, a title known for its demanding requirements. While performance was generally playable, I experienced some judder when navigating the environment, prompting me to cap the frame rate at 30fps for a smoother experience. The Turnip driver kept temperatures in the high-50s to low-70s range, while the system driver resulted in slightly higher temperatures.
Finally, I attempted to run Cyberpunk 2077, which exceeded my low expectations by actually launching on the Galaxy S25 Ultra via DeX. However, the frame rate fluctuated between the low teens and around 20fps, making it unplayable for most users. The game did crash twice in specific areas, highlighting stability issues, yet it was still impressive to see such a demanding title running on a mobile device.
Reflections on the DeX Experience
My initial impressions of gaming on DeX with the Galaxy S25 Ultra were largely positive, despite some frustrations regarding bypass charging and ultrawide resolution support. Feedback from readers indicated that adding an app to the Gaming Hub was necessary for bypass charging, while ultrawide monitors could be supported through the Good Lock MultiStar app.
Samsung’s collaboration with Google to revamp DeX in One UI 8 introduced several missing features compared to its predecessor. A frustrating controller-related bug in One UI 8 was resolved with the One UI 8.5 update, making it essential for Galaxy users to keep their devices updated for optimal gaming performance. While the wireless keyboard and mouse worked seamlessly, allowing for the enjoyment of classic PC games, the experience was not without its challenges.
Conclusion: A Lightweight Gaming PC Alternative
Reflecting on my experiences, it is evident that the Galaxy S25 Ultra can indeed function as a lightweight gaming PC. The evolution from GameHub to GameNative, coupled with the availability of Turnip GPU drivers, has made it possible to enjoy older PC games on a mobile device. While there are still hurdles to overcome, such as compatibility issues and thermal management, the ability to play beloved titles in a pinch is a noteworthy achievement in mobile gaming.
