Lightroom 7.3 Update Huge adjustment lagging

I would find it hard to believe if i'm the only one suffering from this tremendous lag when editing photos.

Has anyone else had 4-6 second lag when making a correction/ editing with lets say the brush tool. You click add your adjustment and literally wait 5 seconds before your edit appears.  Obviously this is critical to my workflow and makes editing and photo a monumental frustrating task. The previous Lightroom MAYBE once in a great while would lag for a second or two which I would say is normal.

I am using a GTX 1080 card, 6g of ram, and only running Lightroom when experiencing this. This is so bad it makes me not want to edit photos at all, just seems strange why it would all of the sudden be so bad. Anyone who might know the cause of this any info would greatly be appreciated. I was so excited to use the new features but their all so slow it renders the program useless to me unfortunately.
