This week I found this programm and checked the graphic memory usage while playing on my main system running with WinXP. Works good. Today I wanted to read out the information of the graphic card of my Win2k system. Trying to start GPU-Z, the following error message appears: ...\GPU-Z.0.5.0.exe ist keine zulässige Win32-Anwendung. ...\GPU-Z.0.5.0.exe isn´t a valid Win32-application. So GPU-Z is actual not supported for Windows 2000. Please make it supported otherwise its strange to say it is.
