A question about LTC miners

[starships]

I'm trying to switch over to LTC mining with my 7950 and GUIMiner scrypt. I ran into a problem regarding the intensity settings, as I'm a very casual miner using the single 7950 in my main pc, I use my pc throughout the day and the miner slows it down dramatically. I notice my GPU usage stays locked in at 99%, with the BTC variant of GUIMiner it scales the usage dynamically. It's much more convenient then manually adjusting the intensity everytime I want to open something on my computer, are there any scrypt miners that do this?
