By enabling the DSP, do you mean setting the DSP emulator engine to LLE or something? The DSP is always emulated in some capacity, else most games wouldn't boot. LLE is much more demanding than HLE; any frame rate drops are not unexpected. If you are using LLE, you'll need to enable LLE on Thread + Accurate VBeam Emulation to get the most from your system without overclocking.
Btw, just thought I'd point out that this game is extremely light on the GPU. Feel free to pump up the graphics as far as you can go. I can easily play this on 4x IR with the max AA for OGL.
