We have just released a new Android virtual machine, called Leapdroid, it is a Windows program that allows you to run Android Apps in Windows. Our focus has been on graphics performance. It outperforms all other players on market, such as BlueStacks, Genymotions, Andyroid, etc... it supports a lot of games, and it it is totally free, you can download it from our website:
From development point of views, we have implemented most features that Google's emulator has, such as compatible adb. Our virtual machine is the only vm that can start adb before vm starts, same as a real device, so you can get the first line of adb logcat. We have also optimized other aspects of the system.
