so i downloaded project 64 and the mini runs it great!

the only problem is I can only run it when it is plugged in. i get about 60 fps when its plugged in, but when i unplug it the fps drop to about 30 and it becomes unplayable.

is this some setting that i can adjust to make it run right or am i SOL?

thanks.

I'm not sure what's wrong I'm afraid. It works just as well when it's not plugged in as when it is not for me.

hummm... its very interesting then. it happens it instant i unplug the mini. and as soon as i plug it in fps jump back to 60.

SpeedStep interfering?

Sounds like it might be speed step. What OS are you running?

Speedstep is a process where the processor is downclocked when the extra speed isn't needed. This is to conserve power and reduce heat output. I am thinking that maybe your mini is set that when it runs off the battery the cpu multiplier is locked.

oh ok. well can i adjust that in the bios or what? it seems dumb that it would be set like that.

I thought I saw the option to disable speedstep in the BIOS?? ...pretty sure. You will run your battery down much faster disabling it though. Your processor will not down clock and will always run at 100% using more power. Here's another thought that I am not sure about but the integrated graphics may also do something similar when running on battery so the graphics chipset consumes less power when running on battery. I'm not sure about this but in dedicated graphics processors this is the case.
