Dolphin became slow after some days of use. What could it be?

Thank you for the fast reply!
I though that this could be a problem too... but the notebook doesn't seems too hot, I know that this isn't the right way to "check" the temperature, but it really seems OK!
I picked Realtemp and did some tests... also donwloaded the latest Dolphin version 3.5 r105

With the PCSX2 Realtemp gave the same results...

I installed a PC game (Sonic Riders) to check if it had the same problems. It is a old game but what I have in hand... and Sonic Riders ran good enough, even with the max settings... but being a PC game it's different from an emulator ¬¬

But if the problem is the CPU temperature, why it is happening just now and not in the first time I used Dolphin??!

Thanks again admin89!
