Currently playing Grandia II on nullDC 1.0.4. I've enabled the 'DSP Emulation' option, under 'Aica', which is necessary to hear lots of sound effects, ambient sounds and some voices. However, at frequent intervals it makes the FPS drop significantly, to as low as 25. This happens most notably during certain spells/attacks, but even sometimes when I'm just walking around it dips to 40 or so. Disabling 'DSP emulation' gets rid of the slowdowns, but also disables the aforementioned sound effects. Does anyone know of a way to remedy this problem? Thanks in advance.
