Setting affinity

I've been trying the setting in task manager where you can set affinity to one CPU in a Hyperthreading P4 system. I'd prefer this to disabling Hyperthreading completely in ther bios as I run several graphics apps that use this. Will this give the same advantages as disabling hyperthreading in terms of Scope's performance and what improvements should I expect to see? (up till now I can't say I've noticed anything)

Ht seem cause problem with multiple creamware cards,I think is a driver problem of scope
HT in not dualprocessor/dualcore is only one optimizazion of cpu pipeline data stream i think

I had terrible audio performance (ticks and pops) with my dual-core system, and the affinity setting didn't help. Not even setting the interrupts to one processor helped; the only solution was to completely disable multiprocessing. Don't know about Hyperthreading, but I imagine it would have the same results.

I don't get clicks and pops anyway (except with really low latency and high CPU synths) but I do have 2 cards and up till now have run HT. Now I've set affinity to one CPU I see no difference so far but its early days.
