100% CPU when playing BoA

Wed Mar 29, 2006 3:44 pm

Hello everybody,

When I have loaded BoA I always have 100% CPU and of course the fan trying to disipate the heat inside my laptop, even when I am not playing and BoA is alone the CPU is 100% so I think is not related to the specs of my laptop:

Toshiba laptop, P4 2,66Gz., 1Gb. RAM, 30GB. HD, 2Gb. page file, NVIDIA GForce 4 420 Go 32Mb.

I do not have antivirus or other applications running in the background at the same time.

¿ What level of CPU do you have with BoA?. Is this 100% normal?.

you'll have 100% CPU with every DirectX application, when they are active (if they are minimized, its another thing, though some still eat all your CPU).

Check in the options window, system tab if you have "cpu always active" unchecked. If unchecked, boa will not use any CPU if minimized or if you are using another application.

Pocus, it is amazing your level of support :hat:

Maybe this is another newbie question but ¿ Several hours playing can harm the laptop?.

Regards.

hum, it depends ;)

Most laptop like the one you have (high end with video card having dedicated RAM) can... I would say its safe.
On the other hand I bought 2 years ago a laptop, for coding and gaming. I burned 2 fans and a CPU with it. This was not a high quality laptop on the other hand...

I sometimes use my laptop for games:

(1) You can usually get third party motherboard monitors which sit in the system tray and continuously monitor stuff like CPU temp. Then, you can tell how hot it is running.

(2) You can get a pretty thin platform (sorry forget what its called) which sit under the laptop between it and the desk. Mine has two fans in the platform powered from the USB hub. That improves air circulation and reduces operating temperatures.

(3) Once a month I blast out the cooling ducts/heat exchange of the laptop with compress air to dislodge dust.

(4) Dell intentionally downclocked their video drivers for my laptop to reduce heat generation.

(5) If you have speed step technology, you could through Windows power management downstep to the DC clock speed and that would reduce heat generation.

I think the platform product's name is called a Cool Pad.

support for CPU throttling down when possible will be added in 1.06.

1.05 is due for this week-end.

Very good idea to include some CPU reduction in the next patches, more and more people are buying laptops instead of standard PCs.

Meanwhile I will work with the Windows Power Management system (is available in my laptop), clean the cooling ducts and made a custom-made platform :sourcil:
