EW Running slow
First thing I would try is create a new profile and see if that helps. Also make sure you have the system power plan set to High Performance.
I regularly run EW 7.4.1.9 with an RX 480 with no issues.
Only if you delete the old one. In this case, you would be adding a new profile as a diagnostic test alongside your existing one.. If it solves the issue, then you more than likely one or more of the databases in the profile have become corrupted. Then you would import your your songs, presentations, and media from the old profile into the new one.Your settings shouldn't change..
I have 4 different profiles on my home computer that mirror different computers at our Church.
Also use a different name for the new profile, and use the Transfer and Backup tool to make a copy of the original profile.
