I'd honestly just suggest the easiest things possible.
Read the quote below, do what is says, if it doesn't help just re-install the game from scratch and remove your FeralHeart game folder completely before installing it again. It's located in C:\FeralHeart in most cases.
How to fix it!
Either you start the game, go into the options menu, click the Video tab, and then change the rendering subsystem and restart the game.
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
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.
Choose the rendering mode not currently selected.
Thanks for helping! It works now.
