RANSAC sucks the life out of my PC

[RobF2]

I know I'm behind the times with a quad core Q660 @3 gHz and Windows XP 32bit, BUT is there some way to tell RANSAC or other CPU hungry routines to leave a little bit of my processing power intact?  Now I'm doing more extended processing of >30-40 subs with the preProcess pipeline script I'm happy to let things run slower in the background as they're be going for many minutes anyway.

I haven't tried fiddling with the PI global priority - just wondering if anyone had any suggestions?

thanks,
Rob

Try to adjust your thread priority in the PI preferences. it's probably set to time-critical or some other inappropriate setting. We had some discussions about that a while back but Juan feels PI should suck up every last Hz it can grab.

Let us know what the current value is and what the effect is when you change it. You may want to do a few benchmarks and see if there's really any performance degradation like the ominous warning in the tool tip suggests.

And yes, you really should update to W7 x64

Thanks Sander - you're a champion! 
I wouldn't have looked there, but perhaps under settings for the PI icon for Windows.  Anything above "normal" let's RANSAC stop even the Windows Task Manager performance window from updating.  I've got it on "normal" and can now at least surf the net or other low processor activities while PI is doing its thaing.  Only a little thing, but helps keep a smile on my face   8)

I didn't do proper performance measures, but can tell PI is still ticking along nicely looking at the processing console.
