There's an ongoing benchmark with building a mandelbrot fractal image in 3000x4000 pixels.

On my machine the results are (miliseconds):

Code:
Intel Dual Core -- AMD Sempron 2400, 1.6 GHz both. 

The test time in miliseconds.

MSVC8 (single, sse) - 3100 -- crashed
turbo delphi-double   7150 -- 8280
turbo delphi-single - 5400 -- 5157
fpc-double           12050 -- 8734
fpc-double-sse2 -  -  4800 -- crashed
fpc-single            4970 -- 4625
fpc-single-sse2 -  -  4460 -- 4875
All versions are required to save their fractal as a bmp, to avoid mistakes.

At least shows that
1) it's unwise to use the Double type in the game development.
2) Free Pascal 2.2.0 has the best code optimizer among all things Pascal
