Hello everyone I just thought I'd let you know that I believe I have found a solution to the overheating issue that some people have been experiencing.
Inside your game folder there is a file called "ogre.cfg". If you open it with Notepad, you will see something like this:
Render System=Direct3D9 Rendering Subsystem
[Direct3D9 Rendering Subsystem]
Allow NVPerfHUD=No
FSAA=0
Floating-point mode=Fastest
Full Screen=No
Rendering Device=Monitor-1-ATI Radeon HD 4300/4500 Series
Resource Creation Policy=Create on all devices
VSync=No
VSync Interval=1
Video Mode=1280 x 1024 @ 32-bit colour
sRGB Gamma Conversion=No
[OpenGL Rendering Subsystem]
Colour Depth=32
Display Frequency=N/A
FSAA=0
Full Screen=No
RTT Preferred Mode=FBO
VSync=No
VSync Interval=1
Video Mode=1024 x 768
sRGB Gamma Conversion=No
Simply change the "VSync=No" lines to "VSync=Yes" and save the file.
This will limit the framerate of the game so that it doesn't overload the CPU.
The actual technical explanation is this:
The human eye only sees content at 24 frames per second. So in reality, anything above 24 frames per second is a waste of
CPU resources. Without VSync, the game will simply run as fast as the CPU can operate. With VSync, the framerate is capped
at 60 frames per second which is MUCH easier on your CPU.
