There is a 'time' command in Windows! No need to install anything! See: http://en.wikipedia.org/wiki/TIME_(command)
There even is a nice time bat-file on Stackoverflow: http://stackoverflow.com/questions/673523/how-to-measure-execution-time-of-command-in-windows-command-line To run Mark Stock benchmark on windows you have to: Step 1: copy xform.exe and rename it cat.exe OR install Mingw which seems to contain a cat.exe Step2: create a file called 'options' in the bench4 directory with this contents: -pa 1.0 -pj 0.02 -ps 1 -w+ -i- -bv+ -dt 0.050 -dc 0.50 -dj 0.0 -ds 0.250 -dr 1 -dp 512 -dv+ -st 0.150 -ab 4 -ar 128 -ad 1500 -as 500 -aa 0.15 -av 0.0 0.0 0.0 -aw 0 -lw 0.004 -ss 1.0 -lr -10 -u- -pd 0.0 Step3: Create a .bat file with this contents: @echo off echo %time% obj2mesh -n 15 -r 16384 lens.obj > lens.msh oconv -f -n 6 -r 16384 materials.rad cube2f.rad > cube2f_instance.oct oconv -f -n 6 -r 16384 materials.rad cube4f.rad > cube4f_instance.oct oconv -n 6 -r 16384 materials.rad scene.rad > scene.oct rpict @viewpoint @options -x 2048 -y 2048 -t 60 -o windows.unf scene.oct pfilt -1 -e +0 -x /4 -y /4 -r .6 -m .15 windows.unf > windows.pic ra_bmp windows.pic > windows.bmp echo %time% pause Step 4: Run the .bat file If you don't want to calculate the time yourself you can use the .bat file on Stackoverflow (I haven't tried it yet). -I believe Greg also mentioned a way to avoid the use of cat in Radiance, but I didn't understood how. :) I guess that was all I had to change.
