Yes i know, it is mining at half of the speed but it still uses 90% of the cpu power....
After you have specified the number of threads, set(if possible use task manager) the cpu affinity to be at core X or whichever you choose. And that's basically it.
I have already set the affinity from the guiminer.
There's a slight possibility it's not working via guiminer. Do it via Task Manager. Also, how many cores do you have?
Only 2 cores.
Then what did you expect? I have a quad core, so if i use one thread that's only 25% of my CPU. For you, it will be 50%. Basically, that is why you have the so called "high cpu usage"
Maybe he expects 50%. That's what I get on my dual-core systems with one thread, and that is what he should be getting based on your post. The 90% that he is getting is significantly higher than 50% I hope someone congratulates me on making a pot as useful as yours...
Yes that's my point...
