How do I get Boinc 7.0.28 to process GPU WU's from different GPU projects? I am attached to Collatz, Moo Wrapper, Prime Grid and Seti Beta for GPU WU's but Boinc will only get and process WU's from Prime Grid. And it downloads 10 WU at a time. I have each project set @20%. I want to d/l 2-3WU from each project and have Boinc switch between them every 120mins and replace them as they finish.

Make sure that at each project's project preferences, you set to use the correct GPU.

E.g. http://boinc.thesonntags.com/collatz/prefs.php?subset=project
Use ATI GPU
Enforced by version 6.10+ yes/no
Use NVIDIA GPU
Enforced by version 6.10+ yes/no

Yes they are all set for my GPU.

I've also got the same issue as sorceress, and I've always had my GPU settings as Ageless suggested. Currently running GPUGRID and Seti@Home for my GPU, but they never switch between each other, even when the setting in the computer preferences is set at one hour or five minutes.
Any help would be grateful.

I don't have a complete answer, but I have BOINC 7.0.36 x64 (Win7 64-bit), and it runs both POEM and WCG/HCC beta properly on my two Radeon HD 7770s. Since I prefer to run WCG, and only want POEM as a backup on my GPU when there is no WCG work available, I set the resource share to "1" for POEM and leave it at "100" for WCG.

I don't know yet if it switches between the two at the right intervals, since I haven't gotten that much WCG work yet, but at least it works to some degree. I suggest updating to BOINC 7.0.36
