Every process only able to use 1 core ?

Today I was wondering why my media converter and my sony vegas were going to slow. I checked the task manager and they were both being limited to 12-13% or 1/8th of my cpu each.

It's a i7 860 with hyper threading on so that explains the 1/8th. But I don't know why these programs can all use multiple cores as they have in the past with me and I can't find anything on google about this.

I've tried setting the affinity, I have plenty of ram, my harddrive is fine.

Unless they're written to take advantage of multiple cores, they won't. And there's no way to "force" them to either.

CPU usage on an i7 limiting to the 10-15% is very common, at least in my experience, simply due to the power of these cores. I have a i7-720QM and the CPUs rarely go above that range unless I am watching a movie, playing games, or using Photoshop that requires a bit more processing power. Also, the programs need to be written to take advantage of those cores, and most software still has not been update to do so.

So, unless you are experiencing some sort of lag from this, I would show no concern. Maybe check the power settings if you are using a laptop to see that it is not on Power Saver mode, which throttles the CPU to save energy.

I'm experiencing a lot of lag, a task that would usually consume around 80% and take 15 mins is only using 13% and taking over an hour. I disabled hyperthreading and then the max is 25% so for some reason all of my usually fast programs that always use multiple threads are only using one thread now.

Also Sony Vegas keeps on crashing because I'm trying to do a task that needs a lot of power, editing a 50 min long clip which is 15.3GB because it's not compressed.
