I've just set up my PCs in a small LAN. My DAW is quite an old machine, with a hyperthreading Pentium IV processor. I was about to install RA and EWQLSC, when I found a paper insert in both manuals, saying that hyperthreading should be disabled for best performance.
I was aware of GS and hyperthreading issues, but so far I've never come across a problem with NI stuff - Gary's instruments don't come with any such warning, and the full blown versions of Kompakt, Kontakt and Intakt are fine. Does anyone know why this is an issue?
I doubt it really is an issue. I ran KP1, KP2 and K2 fine on my old P4 with HT enabled. And as far as I know the Kompakt Player is built on the Kontakt 1 engine, same as is KP1. It certainly is built on the same engine as the full blown Kompakt.
Well, the note says "For best performance". It doesn't say it's a "problem". There's a difference. For applications that are not designed for hyperthreading, there is a performance hit when it's enabled. Ask any gamer.
