Latest publicly-released build. OpenV.E. is a Gradle project--as of this writing, an IDE and JDK 11 or higher are needed to run it.
You will need a JDK to run the IDE to access the game: Oracle.com
Your system should meet these requirements:
RAM: at least 3 GB
PROCESSOR: At least 2 GHz
If your system cannot run JavaFX, it cannot run this game--sorry.
The game should run decently on most modern PCs. A high-performance/gaming PC is ideal, but if you don't have one, there are options within the game to vastly improve performance if need be.
