As of June 2022, compared to other emulators:

| Feature | BS 5.9.620 | LDPlayer 9 | Nox 7.0.5 | MEmu 8.0 | |--------------------------|------------|------------|-----------|----------| | Hyper-V support | Yes | No | No | No | | Android 9 default | Yes | Yes | Yes | No (7.1) | | Multi-instance sync | Yes | Yes | Limited | Yes | | ARM translation | Good | Good | Fair | Fair | | RAM idle (MB) | ~400 | ~550 | ~600 | ~480 |

BlueStacks 5.9.620 excelled in low resource consumption and background instance management but lagged in Vulkan optimizations compared to LDPlayer, which focused heavily on that API.

Updating is seamless and can be done directly within the emulator.

Alternatively, the update will eventually roll out automatically to all users over the coming week.

You will not find version 5.9.620 on the official BlueStacks homepage (they always serve the latest version). To get this specific build, you need the offline installer from the official release archive.

BlueStacks 5.9.620 was not a headline-grabbing release but rather a polish update that fixed real-world annoyances. It remains available as an offline installer on some third-party archives, and many users who dislike newer versions (which may include ads or telemetry) still use 5.9.620 as their daily driver.

If you are running a game that worked perfectly on 5.9.620 but stutters on 5.14+, that specific build is worth keeping as a backup.

Would you like a direct comparison between BlueStacks 5.9.620 and the latest BlueStacks 5.21 (or BlueStacks X) to see what changed?
