After the Developer's Cut release, someone was playing around with dragon combat and discovered increasing the flying speed made it more fun. Initially that was tinkered with thinking it might be suitable for a DLC for Divinity 2, but things kept getting added and it evolved into Dragon Commander.
The minimum requirements for DC are not a lot higher than D2:DC, so it may be able to run the game ok. However, that depends on how much headroom there is in the smooth performance and how necessary the lowest graphics settings are.
Minimum requirements are:
OS:Windows XP SP3
Processor: Intel Core2 Duo E6600 or equivalent
Memory: 2 GB RAM (4GB would be better, especially in Win 7/10).
Graphics: NVIDIA® GeForce® 8800 GT (512 MB) or ATI™ Radeon™ HD 4850
