I only seem to be downloading 1 WU at a time, but as I have a GTX 270, I can get through it in less than 10 hours. Unfortunately, no more WUs download. Hitting "update" only gets "communication deferred 30 secs" and nothing ever happens. So I have to detach and re-attach to the project to get another. Is GPUGrid not entirely compatible with BOINC 7.0.18 x64 (which I'm running)? Or is there something else going on?

EDIT: My global settings are set to maintain 5 days' worth of work, and I have plenty of hard drive space allotted.

Yes, GTX 570. Sorry.

I was hoping to use the GPU exclusively for GPUGRID, but I can't if it won't automatically download new WUs when it's finished. I have the "report results immediately" flag set in cc_config, and it does submit the work shortly after it is complete. Isn't there a way to get more than 1 or 2 at a time? Manual WU download? Anything?

Also, I've only been getting the Long Run WU, and they seem to only use ~70% of my GPU (I have a little script that automatically adjusts the process priority to "normal" from the default "below normal", but 70% is the max it ever gets to). Is there a setting somewhere that I'm not aware of that would enable closer to 100% use? Or maybe run 2 WU in parallel? I have yet to come across a functional app_info for GPUGRID that would allow that.

Where do I set the minimum and maximum work amounts? My computing preferences for BOINC say that I'm always connected to the internet, and I should maintain enough work for 2 additional days.

Yes, like I said, I have had to reattach to get new WUs. I went ahead and "merged" the computers via your link (thanks).

I still only seem to be getting 1 WU at a time, then nothing until I reattach.
