Question

Hi guys, 

I couldn't  find anything about how to query the processors clock speed in metro apps so far.
Is there a possibility to do so ?

Kind regs,

Hi Roman,

If you are looking at processor speed as a way to adjust gameplay, then an alternate approach would be to draw a bunch of stuff on a splash screen and time it.  You could use QueryPerformanceCounter/QueryPerformanceFrequency to do so.  Then, you would have an indicator of both CPU + graphics capability in a practical, "what can this system draw, as it relates to my app" perspective.

I hope this helps!  Good luck!

Hi Dan,

Thanks for your reply. Well, i use the couple QueryPerformanceCounter/QueryPerformanceFrequency for not too timecritical measurements. 
But ofcourse to get the elapsed ticks between each frame.

I just needed the core speed for profiling purposes.
I would like to use the processor core speed in combination with RDTSC to get the elapsed ms of certain sections of the code.
These profiling-routines get called a many thousand times a frame. Anyway it's just for debugging / profiling purposes to see which code runs
faster and how much. I can still do this now - it's just that i won't get the results in milliseconds which would be nice to compare
it to other computers / os'. But, oh well.

Thanks, Roman
