First, try opening the ogre.cfg file located in the main Feralheart folder and take a look at the first two lines. It should either say either one of the following: QuoteRender System=Direct3D9 Rendering Subsystem[Direct3D9 Rendering Subsystem]orRender System=OpenGL Rendering Subsystem[OpenGL Rendering Subsystem]Now, if your ogre.cfg file is set to (for example) the Direct3D9 rendering subsystem, change it to the OpenGL rendering subsystem, and vise versa. Next, restart your game and see if the issue is fixed. If that does not work for you, I'd recommend following the previous advice of reinstalling the game completely. Good luck!
Render System=Direct3D9 Rendering Subsystem[Direct3D9 Rendering Subsystem]orRender System=OpenGL Rendering Subsystem[OpenGL Rendering Subsystem]
