Users praise GI Tuner for boosting FPS and smoothing gameplay by enabling Vulkan and core overclocking across devices and titles like Genshin Impact and Star Rail. However, many report stability problems: app crashes or failing to open, settings not saving, and folder/path permissions issues (Android 14+ compatibility, HSR folder tracing). Vulkan vs OpenGL behavior is inconsistent across games. Some devices see major FPS gains; others experience lag or no effect. Update-related bugs and reliance on workarounds (Shizuku) appear frequently. Overall: powerful tuning tool with significant caveats around reliability and file access.
Pros
Significant FPS gains and smoother gameplay when configured (stable frames in games like Genshin Impact and Star Rail).
Supports Vulkan and enables GPU core overclocking to boost performance on supported devices.
Works across a range of devices and popular games, with long-term use reported by users.
Alternative setup via Shizuku lets users access its features after OS updates.
Helpful for low-end devices to achieve playable FPS even on demanding titles.
Cons
Crashes or cannot open the app, especially after updates or on certain devices.
Folder/file access and path issues: cannot create folders or locate the required game folders (Android 14+ HSR issues).
Inconsistent Vulkan vs OpenGL behavior across games; some games improve with OpenGL instead.
Settings sometimes do not save or apply reliably; configuration changes may not persist.
Update compatibility issues and bugs requiring workarounds; ads on the apply screen hamper usability.
Recent reviews
While the app developer might have good intentions about the purpose of his app. I and many others have faced a great many problems in troubleshooting the app to do its singular function, as with the software update of android 11 and higher, I had to resort to using Shizuku to achieve the same levels of functions as it did before the update. But once I got over the herculean task of actually operating the app, it would simply not save my settings. And has effectively ruined my day. Not recommend

been using it for some years its a good app to optimize game performance especially fps of the game but one thing i've just noticed in 6.3 update of genshin impact was when i change to vulkan graphics it doesnt change anymore i opened the game and the game's graphics api says its opengl so i tried again but its the same, i hope this bug will be fixed, but anyways thankyou.
