guiminer started eating my CPU

[tonto]

Hey all, just installed another 5770 (already have one), and I started back up guiminer and had a couple of my miners take the new card, and all a sudden my CPU spiked to 100%.  I can't seem to bring it back down short of using the -s flag, but then my GPUs take a hit.
 
so right now I have a happy medium of -s0.005 until I can find a solution.  Thanks!

If you use phoenix, try to set AGGRESSION=9 or lower, with higher Numbers over 9, CPU usage grows.

well I don't know what guiminer is based on.  Is it based on phoenix?

It is since the last version.

Download Version 06/14 and go on [File] -> New miner -> phoenix miner
You can find good flags for all cards here : https://en.bitcoin.it/wiki/Mining_hardware_comparison

With the flag AGRESSION you can control how much computing power is taken, higher numbers, more cpu usage, more lags on the Desktop, but higher MH rates.
