dx9 blitter.., no - its missing half the features of the d3d blitter. also d3d7 works fine out of the box, most of the time the user has to install the dx9 runtime package for dx9... (even on win8+)
dx9 blitter also It doesn't have pause / recording/replaying icons, and is missing the chat feature for kaillera.
Also most sound cores run at less than 44100hz (hw-rate), so resampling to 96k will be even more lossy and induce possible aliasing than resampling to 44100/48khz.
