I recently joined COllatz and am crunching on GPU's only. I am using a power app downloaded from the COllatz page. I have two GPU's, and one seems to be very slow now in updating the screen. I tried adding <cmdline>L3 I5 S1</cmdline> to the app_info.xml file, restarted BOINC, but that didn't seem to help. I was previously running MIlkyway@home on my gpu's and did not have that problem before. How can I get some of my screen update performance back?

I've got 3 monitors hooked up, although I can't tell you which card is driving which monitor. I honestly thought my slower 8600GT was driving my left monitor, and my newer GTX260 driving my center and right monitors, but now I think the 8600 is driving the right monitor, which is where i have my email program displaying, and the slowness is driving me nuts. I don't want to move email over to the left monitor as it is farther away and harder to see.

Can anybody offer any assistance in this regard?

Option 1. Change the settings so that it doesn't use the GPU when the computer is in use. That the the video response will only be slow when you are not using it.

Option 2. Change the settings in the cc_config.xml to omit using the 8600GT. For the complete list of settings, check out http://boinc.berkeley.edu/wiki/Client_configuration

Option 3. Change where the monitors are plugged in so the 8600 is running the left monitor.

Option 4. If you have an open slot add another GPU. e.g. a cheap PCI one that doesn't crunch and run your left monitor off that (not exactly practical if you don't have the cash, the slot, or also use it for gaming)

Option 5. Lower the L setting and increase the S setting such as L1 I5 S3. It may slow down your crunching considerably though.
