Lowering cpu load

[supperpiccle]

I am running the first example in irrlicht and noticed on my quad core it uses the equvilent of a whole core(some on each core) i am using ubuntu 13.10 and was wondering if there was any way to lower the cpu load. I just think for a small app it is rediculous to use that much(i have intel core i5 4670k should rape the first example no sweat)

May be use the sleep function inside the loop.

Use Vsync? Most game player's preference is for high frame rate, which implies that the CPU should not pause.

In any case, you should be able to use two cores with a properly written app. So the example is using only 50% of the expected CPU utilisation!

The first example uses software rendering...

Put

Code: Select all

 
device->yield();
 

in your render loop.

Use

Code: Select all

device->yeild()

this code just pauses the processor for a brief amount of time to let it cool down.

i tried using vsync in the createdevice function but didn't change anything...looking up documentation for it it seems as if it is only for fullscreen?

Hey i followed the indirect advice of hendu and yes software renderer must use cpu. When i changed to opengl(cause im on linux!:) ) it didn't make the cpu freak out. Thanks for the help!

Also, since your game loop doesn't limit the frame rate in any way, the engine is free to update as fast as possible which can eat all the processing power
