"Optimizations" aren't the issue here - hacks that break the application
but still make the benchmark appear to render fine are.

Here is an article discussing the issue:,3973,1086025,00.asp

Essentially, they completely broke the rendering engine by hard-coding
assumptions about where the camera would be into the driver.  Move the
camera slightly (such as in the developer version of 3D Mark), and
everything is a garbled mess.

This defeats the entire purpose of a benchmark as a real-application
performance test, since the benchmark is converted from a simulation of
real game rendering calculations to instead be a glorified movie.
