HI

I have done 2 test, then i think :

Hyperthreading is very bad for dolphin.

this is picture of my test with i3 330m 2.13GHZ Hyperthreading :

first situation : http://img831.imageshack.us/i/httest1.png/
second situation : http://img204.imageshack.us/f/httest2.png/

For the first situation :

Dolphin is running, i have 25fps(so not fullspeed) and cpu working at 60%

For the second situation :

2 dolphin is running, 2 dolphin are not fullspeed but my cpu is working 100%.

Then, i want than during my first situation, my cpu must be 100%

Thanks and sorry for my bad english Big Grin

Yes, it's a notebook, my graphic card is ati mobility 5650 1G but as you can see, my graphic card is loaded at 40% max.

Thanks for your answer Big Grin

Turn off audio throttle. Turn on use fps for limiting. Set the framelimiter to 30. Turn on lock threads to cores. Try it now.

If that doesn't work try turning off efb scaled copy.

Unfortunately, even with your setting, load cpu max is again 60%. with lock thread to core, it's worse.

I don't understand

Sad

don't use lock thread to core. and you need at minimium, 3.2Ghz

This is not a true statement, the clock speed doesn't = real speed.

As an example, I can overclock a Pentium 4 to 4 Ghz and it will still be slower than a Core 2 Duo, i5 or i7 Under clocked to 2.0Ghz.

He knows that. He's just saying that for this game 2.13 GHz on any modern cpu is not sufficient.
