I had a similar problem with stuttering when using Halion and was still present even when I switched the audio driver to NME.

Solution so far for me is to use asio4all v2, so far so good no stuttering in Halion, Set as default synth, even with a mix of midi and realtracks.

And its an old computer as well, with only 4gb of Rab
