Hi all, I'm a new player

I just installed Xsyon and start the game, but I have very crappy performances.

My config:
- Intel Core i5-3470 3,2GHz
- 16GB ram
- AMD Sapphire Radeon R9 290X 4GB
- Windows 7 64 bit

How can I have 12fps @1920x1080 with ALL setting to Off or the minimum value? And it goes a little worse with all at max...

There are some "hidden" settings to do?
