I've spent some time with the Windows Subsystem for Android on Windows 11, and overall, the performance is quite impressive for integrated app usage. It feels smoother than I'd expected, although some heavier apps can lag a bit, but that’s not too surprising given the complexity of emulation.
In terms of limitations, one thing that sticks out is the limited access to Google Play Services, which can be a dealbreaker for apps that rely heavily on it. You might need to sideload APKs for certain apps.
When it comes to must-have apps, I found that productivity apps like Microsoft Office or even Kindle run nicely, maintaining steady performance without crashes.
Comparing it to BlueStacks and Genymotion, WSA is more seamless since it's baked into the OS, meaning fewer third-party resources hogging system performance. However, those emulators can offer more flexibility in terms of Android version and configuration.
For optimizing the experience, I recommend keeping your Windows updates current and ensuring virtualization is enabled in BIOS, which improves performance. Restarting the WSA's virtual machine if you notice any slowdowns can also help.
Overall, it's a promising feature that bridges the gap between PC and Android app usage, though it still has room for improvement.
