odd buzzing sound at run time [SOLVED]

[oringe]

When I run my Irrlicht program, I hear this weird buzzing sound. It changes pitch and frequency along with changes in my program's state. It's not loud, but very annoying.
I heard it before I implemented irrKlang, and ignored it hoping it would go away once I implemented sound in my game. But it is still there : (
Anyone experience the same? Any ideas how to get rid of it?

It's because of high framerate in your application (Probably v-sync is off, and you're not limiting it).
I don't know if it's the gpu that's causing it or not, but I'm sure it's because of high framerate
Just run any other application that has high framerate and you'll see.

Yeah, it's the power supply/regulator of the GPU (or transitively from the CPU/board, where ever the worst components are used). This will remedy once your app has more to do on each frame.

That sounds right. I'm getting around 2K fps at the start of my scene, and I'm doing nothing to limit it.
Turning on vsync cleared that right up

What would be the best way to limit my fps? -see these threads ->

maybe it would be a good idea that the engine had a method so you could define a desired framerate?

[Abraxas)]

yup, just loop device->run() if a timer is less than your framerate timer. reset on drawing a frame of course.

I'm glad to gear that it was frame rate. I was starting to worry. Thanks for the info.

There are quite a few different ways to do it (I think, read some article about this ages ago), so it's probably best to leave it up to the user
