(slightly) overclock your detonator, without risk and without opening your computer ...

Chankast is CPU limited, not videocard, so overclocking your video card core/mem will do absolutely nothing for Chankast.
The reason lower CPU gives more FPS is because you're virtually underclocking the SH-4 (the Dreamcast's main CPU), allowing your CPU to do more, as it doesn't have to work as hard at say 100 CPU.

No, the emulated CPU runs at a lower speed, causing your physical CPU to have to do less to emulate the emulated CPU.

That depends on the game and the speed of your computer. Guilty Gear X isn't the best example due to it not being very intensive. Try running something like SA2 at 50, you'll see the emulated CPU causing slowdown, not your cpu.

I think we need some clarification here. So here goes:-
Chankast is not a real DreamCast it is a program that simulates various functions of a real Dreamcast in order to allow the execution of real dreamcast software on a current PC.
Like any program certain aspects will require more of the host PC's processing power than others at times.
The spam listed above doesn't really prove much at all. It's one case scenario, demonstrating Chankast's power at emulating the Dreamcast running a rather simple game (ie very few 3D translations and limited alpha processing).
When we change the speed of "emulated SH4" (DC's CPU) we are really only changing the amount of time Chankast is giving it in relation to the other emulated devices (sound : ACIA/Redbook Audio, gfx : PVR2 and GD-ROM reader) that make up the rest of Chankast's emulated suite of devices that work in concert to simulate a working Dreamcast. If we give more of the host PC's clock cycles to the emulated SH4 (by pressing + numerous times), we, in effect, take some of the same clock cycles away from the other emulated devices as mentioned before. The reverse is true in the SPAM mentioned above : taking away clock cycles from the emulated SH4 gives more of them to the rest of the devices, in this case the emulated PVR2 gfx engine, meaning that we see an overall increase the number of frames per second.
This only applies on a case by case basis, as different Dreamcast programs (games ands apps) may require different aspects of the emulated devices to be 100% operational (ie not having the host PC's clock cycles taken from) to remain functional.
It would be nice if people would recognise Chankast as an emulator and not treat it like a game. It's a serious peice of software, that has taken quite some time to come to the current wonderful stage that it has reached.
Cheers,

Why does everyone think I'm being rude to them lately? 
I meant nothing by it. Maybe I should use more smilies? :icecream:
