Hello, I'm having a problem with DarkGDK. While my computer is definitely powerful enough to run this code at a high frame rate, it only runs at 50fps.

+ Code Snippet

#include "DarkGDK.h"

void DarkGDK ( void )
{
	
	dbSetDisplayMode( 1920,1080, 32 );
	dbSyncOn();
	dbSyncRate( 0 );

	dbBackdropOn();

	while( LoopGDK() ){

		dbText( 0,0,dbStr( dbScreenFPS() ) );
		dbSync();

	};


	// and now everything is ready to return back to Windows
	return;
}

Whereas the equivalent in darkbasic Professional runs in excess of 200fps.

+ Code Snippet

set display mode 1920,1080,32
sync on:sync rate 0
backdrop on

do
text 0,0,str$( screen fps() )

sync
loop

Specs:

AMD Athlon X4 640 @ 3.2ghz
4GB Ram
ATI 3000 graphics

Any ideas as to why this is happening?

Thanks

The original GDK that you've downloaded is capped at it's frame rate. There is a way around it (somewhere in the forums). But the updates have fixed that simple issue.

Are you sure of this? I've updated to the latest version. I will try replacing the files again.

EDIT: I didn't realise DGDK had vsync enabled by default. I've fixed the issue now, thanks.

Thanks
