Lossless Scaling Frame Generation now available for Android gaming

At a glance:

• Developer FrankBaretta has ported the Lossless Scaling Frame Generation tool to Android, bringing AI-powered frame generation to mobile gaming
• The feature is integrated into GameNative app version 0.9.1 and requires a $7 PC copy of the app plus Snapdragon processors with Adreno 600 series GPU or newer
• While capable of boosting frame rates significantly (30fps to over 80fps), the Android version has notable latency issues (50-80ms compared to Linux)

What is Lossless Scaling Frame Generation?

Frame interpolation has long been a notable way to offer a smoother gaming experience, but PCs and other platforms have since stepped things up with frame generation, which uses AI to create additional frames. Lossless Scaling Frame Generation (LSFG) is one of the most notable frame generation tools available, originally released on Steam. This utility uses Vulkan to deliver frame generation in a variety of games, including titles without built-in frame generation or scaling capabilities.

The technology works by intelligently generating intermediate frames between existing ones, effectively increasing the frame rate without requiring additional rendering power from the game itself. This can result in smoother animations, reduced input lag in some cases, and an overall more responsive gaming experience. For PC gamers, this has meant being able to enjoy demanding titles at higher frame rates even on mid-range hardware.

The Android Port

Developer FrankBaretta recently released an Android port of the LSFG utility, bringing this advanced frame generation technology to mobile gaming. The good news is that this feature is already integrated into version 0.9.1 of the GameNative app for playing PC games on Android. In fact, the option is integrated into the quick access menu, allowing users to seamlessly make adjustments as they see fit during gameplay.

However, there are some requirements for users who want to take advantage of this feature. The mobile port requires a copy of the $7 PC app. As noted in the GameNative changelog: "If you enable in container settings, you will be prompted to download the lossless scaling app if entitled in Steam, otherwise told to buy it." Furthermore, the feature requires a Snapdragon processor with an Adreno 600 series GPU or newer, which limits compatibility to more recent flagship Android devices.

Performance and Limitations

The developer of the Android port notes that users can expect 50 and 80 milliseconds of lag compared to the Linux version. This is due to technical limitations on the Android platform. "On non-rooted Android there is no equivalent to Linux's Vulkan implicit layer mechanism. Android 12+ explicitly blocks loading external code into non-debuggable processes, so this app cannot hook another app's Vulkan swapchain. Frame generation runs on a MediaProjection screen-capture stream instead, and the result is composited in a system overlay over the target."

Despite these limitations, the performance gains can be significant. A video uploaded by the GameNative X account shows that The Last of Us Part 1 can go from 30fps to over 80fps with this frame generation solution. Meanwhile, some users have reported going from 30fps to 60fps or 60fps to 120fps in various titles. However, it's worth reiterating that the Android version of this feature has significant latency issues. So you might want to stay away from the option in games that require split-second reflexes. It's also worth noting that LSFG isn't a miracle tool, so you shouldn't expect great results if your Android device struggles to maintain a playable frame rate in the first place.

Competitive Landscape

GameNative isn't the only PC gaming app to adopt frame generation smarts in recent days. Prominent app GameHub recently gained an AI frame generation feature as part of version 6.0.1, though it's unclear whether this is based on the LSFG utility or a different implementation. This suggests that frame generation is becoming an increasingly important feature for PC gaming on mobile platforms as developers look for ways to improve performance without requiring more powerful hardware.

The addition of frame generation capabilities comes as mobile gaming continues to grow in popularity and sophistication. With devices becoming more powerful and display technology improving, the gap between mobile and PC gaming experiences continues to narrow. Features like LSFG on Android represent another step in this direction, though technical challenges remain, particularly in terms of latency and compatibility.
