I saw this article linking to a stupid thread on neowin about 3dmark03 "cheating" and decided to 1-up it.
this program will let you cheat adjust the speed of your system clock to get whatever benchmark results you want.
Here is source:
#include <iostream>
using namespace std;
#include "stdlib.h"
#include "windows.h"
int main(int argc, char *argv[])
{
if(argc<2)
{
cout << "Usage: setClockSpeed xxx where xxx is the percentage of normal clock speed you want to run\n"
<< "Example: setClockSpeed 50 will cause your system time to update 50% of the normal amount so your system will benchmark twice as fast\n"
<< "setClockSpeed 200 will cause your system time to update at double it's normal rate so your system will benchmark twice as slow\n"
<< "setClockSpeed 100 will return the clock speed to normal\n"
<< "Decimals can be used so for example setClockSpeed 66.666 will go make the clock run about 2/3 the normal rate\n";
return 0;
}
//must first give self access to adjust time
HANDLE processHandle = GetCurrentProcess();
HANDLE tokenHandle = NULL;
if(OpenProcessToken(processHandle,TOKEN_ADJUST_PRIVILEGES,&tokenHandle)==0)
{
cout << "You don't have rights to change your own access privileges\n";
return 0;
}
LUID timeAdjustmentLUID;
LookupPrivilegeValue(NULL,SE_SYSTEMTIME_NAME,&timeAdjustmentLUID);
TOKEN_PRIVILEGES *newTokenPrivileges=(TOKEN_PRIVILEGES*)malloc(sizeof(DWORD)+sizeof(LUID_AND_ATTRIBUTES));
if(newTokenPrivileges==NULL) {
cout << "Failed to allocate new access privileges\n";
return 0;
}
newTokenPrivileges->PrivilegeCount = 1;
newTokenPrivileges->Privileges[0].Luid = timeAdjustmentLUID;
newTokenPrivileges->Privileges[0].Attributes = SE_PRIVILEGE_ENABLED | SE_PRIVILEGE_USED_FOR_ACCESS;
if(AdjustTokenPrivileges(tokenHandle,FALSE,newTokenPrivileges,0,NULL,NULL)==0)
{
cout << "Failed to grant privileges to adjust system clock\n";
return 0;
}
free(newTokenPrivileges);
double newClockPercent = atof(argv[1]);
DWORD defaultTimeAdjustment;
DWORD defaultTimeIncrement;
BOOL adjustmentDisabled;
GetSystemTimeAdjustment(&defaultTimeAdjustment,&defaultTimeIncrement,&adjustmentDisabled);
DWORD newTimeAdjustment = newClockPercent/100.0 * defaultTimeIncrement;
cout << "default clock increment: " << defaultTimeIncrement << " new adjustment: " << newTimeAdjustment << "\n";
if(newClockPercent==100.0)
{
SetSystemTimeAdjustment(defaultTimeIncrement,TRUE);
}
else
{
if(SetSystemTimeAdjustment(newTimeAdjustment,FALSE)==0)
{
cout << "Attempt to adjust clock speed failed! GetLastError()=" << GetLastError() << "\n";
}
}
return 0;
}
Edit: added code to have the program grant itself privileges to adjust the system clock (you apparently don't have this by default even as Administrator).
