I don't know if this is really a strategy, but I figured that this combination of graphics works well for slower CPUs without crashing them:
These are off:
Specular Effects Detail
Font Texture Detail
Font Shadow
These are on Medium:
View Distance
Terrain Texture
Terrain Resolution
Lighting Detail
Shadow Detail
Water Detail (for faster computers, this can go to high)
These are on High:
Detail Objects
Object Detail ( :huh a little redundant if you ask me, but...)
Environment Detail
Animation Detail
Object Texture Detail
These are on Low:
Overhead Camera Distance
Oh, I forgot. This graphic change will make the Bengal tiger actually look good! :shocked Also all other animals will look better, and the "clean but dirty hide" glitch is erased.
