What were the tests that WinG did to evaluate video cards? - The Old New Thing - Site Home - MSDN Blogs: "He discovered all sorts of crazy shenanigans. Like a video driver which compares the string you ask it to display with the text "The quick brown fox jumps over the lazy dog." If the string matches exactly, then it returns without drawing anything three quarters of the time. The reason: Benchmarks often use that sample string to evaluate text rendering performance. The driver vendors realized that the fastest code is code that doesn't run, so by ignoring three quarters of the "draw this string" requests, they could improve their text rendering performance numbers fourfold."
