AMD Athlon(tm) 64 Processor 3200+

Framerate: 22.560120 fps

In my case at least it gone worse (or the new version made the measuring more accurate?).

when ran from 800*600 res it has no flickering... 1024*786 - has some filckers..
but for both gave about the same result.. Very Happy

It's difficult to change the resolution...

Thank you for sharing your work. I understand multiple resolutions was not the original intent and your help is much appreciated.

Attached is a small modification for other resolutions - which unfortunately does not work. Maybe it is my video card or some other problem? I believe all the changes you have indicated have been made.

[edit] appears to be the bytes per line, change IMUL ESI,EAX,SCREEN_WIDTH*4 to:

Code:

mov esi,eax
imul esi,[ddsd.dwLinearSize]

I don't know that ddsd.dwLinearSize contains bytes per line. Thank's for sharing it.

I don't change the measurement.Maybe the reason is

Okay, I see that you interleave the instructions. Sometimes it can be benefitial also to keep the blocks united and just do the iteration-end-check in the end.

Maybe this optimization is processor-dependent.

Fixed BIOS settings result in slight increase:

You can't disable the thermal throttling, it is an automatic function of the CPU to prevent damage.

Then what does TM1 Enable or TM2 Enable of MSR 1A0h do exactly, I thought this enables or disables thermal throttling in recent Intel CPUs ?

Very nice Kempis

Erm, I don't know, perhaps at the kernel level the throttle can be disabled Confused

Sounds scary, I certainly hope not, else a virus could cause real damage! Just disable throttling and run all cores at 100%, most users wouldn't notice until too late.

Kempis, beautiful fractals!
But I haven't been patient enough for the first time having your programm launched Smile

I don't think it would be as bad as that, AFAIK the CPU should still shut down if it gets really really hot ie enter a halt state and need resetting to start up again. Hopefully the kernel will take notice before this happens and save our data but who knows. What if active cooling stopped ie a broken fan in a laptop, would even a working throttling system be enough to keep the cpu below the danger line at maximum demand?

I can answer that because one of my laptops suffers from this problem. The PSU abruptly shuts down the whole system. Although I hope that this is an automatic hardware operation, I would not be happy to learn that something as stupid as a kernel bug/virus could make my laptop melt and burn with no hardware protection.

I'm sorry that I don't collect your benchmark result. Actually it just for fun.

BTW, So, is the program dangerous, and can cause serious damage?

So, I want to make screensaver version. But how? The CPU usage is too high. If it's delayed, the animation will be slow.

Maybe if you generate the set before hand and save it as a bunch of pictures and make a slide show out of them?

Thank's for your suggestion... but it's slideshow, not animation
