Do you generally trust software updates to fix hardware performance issues in your devices?
Recent testing of the Google Pixel 11 revealed inconsistent CPU core scheduling that resulted in diminished gaming performance following the 7.1 update for Genshin Impact. The findings suggest that current software tuning, rather than inherent hardware constraints, may be preventing the device from matching industry standards.
Why it matters
The performance gap highlights the critical role of scheduler optimization in mobile silicon, where efficient distribution of tasks between high-power and high-efficiency cores determines sustained frame rates. Because the issue appears tied to software, it remains a potential area for improvement through future firmware updates.
During gameplay, the Pixel 11 Tensor G6 C1-Pro cores averaged 2.1 GHz, while the Ultra core ran at an average of 1.41 GHz. These settings yielded a 1% low frame rate of 11.7 fps, significantly trailing the stable 60 fps benchmarks achieved by the Xiaomi 15S Pro and iQOO 15.
The players
A global technology conglomerate responsible for the Android operating system and the custom Tensor line of mobile system-on-chips.
Xiaomi
A consumer electronics manufacturer known for its high-performance smartphone series utilizing competitive mobile chip architectures.
iQOO
A smartphone brand focused on performance-oriented hardware and gaming-centric software optimizations.
The details
Reviewers used PerfDog—a performance diagnostic tool that logs mobile device hardware metrics—to track frame rates and CPU core frequencies during play sessions. The logs revealed erratic task allocation across the Tensor G6 architecture, which forced the processor to run at lower average clock speeds during intensive scenes. This scheduling behavior suggests the operating system is failing to correctly assign workloads to the appropriate performance clusters, causing the frame rate drops observed in titles like Genshin Impact.

The Tech Race
This performance deficit places the Tensor G6 at a disadvantage against the latest flagship silicon found in the Xiaomi 15S Pro and iQOO 15. The findings serve as a benchmark for Google's ongoing effort to optimize its custom processor stack to meet the demands of modern mobile gaming.
Current Pixel 11 users may experience erratic frame rates in graphically demanding titles like Genshin Impact and Zenless Zone Zero until a system update is released. Performance remains inconsistent compared to competitor flagship devices, regardless of user-adjusted graphical settings.
The takeaway
The performance bottleneck identified here serves as a reminder that hardware output is tethered to the efficiency of the underlying software scheduler. Owners should monitor official update logs from Google for patches specifically addressing core management or game compatibility.
