Minds an AMD 3000+ - which is why I would like the BM executable to test it on.

I've included the executable for the above source code - so you can try it on your machine.

Quote: "A more relevant test would be DGSDK against Max, as the compilers are arguably a better match for each other."

Can someone explain why it's a better match? Is the Max compiler as good as the VC++ compiler!?! Hard to believe.

well it's much much better than either blitz3d or DBP. i think i've heard people say that it "approaches" C.. of course, that's just a qualitative measurement.

"when it's done" means "we have no idea, we forgot to do that; we were hoping you would all forget we promised <insert exotic promise here>"

Clearly the 'Max compiler is *not* as good as the VC++ compiler. However I think that the 'Max compiler is closer to the VC++ one in terms of speed than the 'Max compiler is to the DBPro compiler.

At the moment that idea appears correct - BM appears to be approx 2.5 quicker than DarkSDK

Come next year, I do hope all the debugging stuff is taken out, and the whole system is speeded up.

That is on a very simple test though - I expect you'll find that the difference is less pronounced with proper 3D scenes or proper 2D game scenes.

Updated source code :

#include "windows.h"
#include "DarkSDK.h"
#include "stdio.h"

LARGE_INTEGER	gameSpeed,oldGameSpeed;

void DarkSDK ( void )
{
register int x,y,totalR,totalFps,fps;
float rot=0.0;

dbMaximiseWindow();
	totalR=0;
	totalFps=0;
	fps=0;
	if (QueryPerformanceFrequency(&gameSpeed)==false)
	{
		MessageBox(NULL,
					"Sorry.  This computer doesn't have a high-frequency timer.",
					"* No Timer *",
					MB_OK | MB_ICONEXCLAMATION);
		return;					
	}

dbSyncOn();
	dbSyncRate(0);

dbLoadImage("ship_light.png",1,1);
	dbSprite(1,0,0,1);
	dbScaleSprite(1,10);

QueryPerformanceCounter(&oldGameSpeed);
	QueryPerformanceCounter(&gameSpeed);

while (LoopSDK())
	{
		if (dbEscapeKey())
		{
			printf("Screen FPS:[%d]",totalFps/(totalR-50));
			return;
		}

for (x=0; x<20; x++)
		{
			for (y=0; y<20; y++)
			{
				dbPasteSprite(1,x*50,y*50);
				dbRotateSprite(1,rot);
				rot+=3.0;
			}
		}

dbSync();
		dbCLS();

fps=(int) (gameSpeed.QuadPart-oldGameSpeed.QuadPart)/100;
		oldGameSpeed=gameSpeed;
		QueryPerformanceCounter(&gameSpeed);
		totalR++;
		if (totalR>50)
		{
			totalFps+=fps;						
		}
			
	}
}

#include "windows.h"

					MB_OK | MB_ICONEXCLAMATION);
		return;					
	}

	dbSyncOn();
	dbSyncRate(0);

	dbLoadImage("ship_light.png",1,1);
	dbSprite(1,0,0,1);
	dbScaleSprite(1,10);

	QueryPerformanceCounter(&oldGameSpeed);
	QueryPerformanceCounter(&gameSpeed);

	while (LoopSDK())
	{
		if (dbEscapeKey())
		{
			printf("Screen FPS:[%d]",totalFps/(totalR-50));
			return;

		for (x=0; x<20; x++)

			for (y=0; y<20; y++)
			{
				dbPasteSprite(1,x*50,y*50);
				dbRotateSprite(1,rot);
				rot+=3.0;
			}
		}

		dbSync();
		dbCLS();

		fps=(int) (gameSpeed.QuadPart-oldGameSpeed.QuadPart)/100;
		oldGameSpeed=gameSpeed;
		QueryPerformanceCounter(&gameSpeed);
		totalR++;
		if (totalR>50)
		{
