Hey, that's good news.
I'm happy to read that it even runs on ancient machines :o)
(my own is also going to be EOL soon)
Is it still playable on your system or do you experience annoying lags sometimes?
Would you mind telling me the frame rate the game can achieve on your system?
You can see it when you enable debug info by pressing "D" in the game and looking through the first zero of the score in the upper left.
You can hide debug info by pressing "D" again.
The specs in the release notes are just a recommendation since I don't have any other reference yet.
Meeting these specs should ensure that the game runs with constant 60fps.
However, the game automatically adapts the wave calculations to 30fps with a little loss of accuracy.
I hope you enjoy the game,
your feedback is highly appreciated.
