Is there a way to only download projects that can be completed in the deadlines requested or different projects that will run in less time. Previously I was able to complete projects but not since the New Version has been active.

You might want to visit wuprop@home https://wuprop.boinc-af.org/ and review the typical crunching times for various project applications and tasks to make a guided decision about which projects can be crunched within the deadlines with your hardware.

When there are not GPU tasks for GPUGRID I run Milkyway@home and Einstien@home. There is also a small amount of GPU work for World Community Grid which squeezes in between those.
