What are you system specs? Go to "About this Mac" and list the GPU (graphics card) that is the most important thing I'm concerned about. Other good info is the Processor (CPU), RAM, OSX version, and Resolution if possible.
Have you tried setting everything to Min/Low with a low resolution and still no good?
i dont know how to lower the resolution.
Processor 2.3 GHz Intel Core i5
Memory 4 GB 1333 MHz DDR3
Graphics Intel HD Graphics 3000 384 MB
Software Mac OS X Lion 10.7.5 (11G63)
You and your tinker toy video don't get to do that until after you meet the OSX version requirement, 10.8.4
