Sometimes you aren't able to even enter the game, and all you can hear is the menu music, or it just crashes directly after launch. Those who experience this can enter the feralheart folder located in C:\FeralHeart at standard, find the file called "Ogre.cfg" and open it with wordpad.
This file works just as the ingame options menu, but instead of buttons and sliders, there's text.
What we're interested in is the top row

Set the top row text so it is just like in the picture with the text
Code:
Render System=Direct3D9 Rendering Subsystem
Save the file, and close it. Next time you run the game it should boot with the new settings you applied.
