Major performance issues with Premiere Pro 15.2

Having some major performance issues with this latest update. 
Warp stabilizer and other effects now needs to be rendered "manually" always worked like a charm before with cuda.
Bringing up the scopes in the tab takes for ever. And overall it seems to drain the system. 

Scrubbing on the time line is also very uneven and choppy causing spikes. 
Even though we're trying to edit h.264 all-i 1080 video from an entry level Canon SL2. 
And there's an almost rolling shutter like look on the footage on the program monitor. Even on locked off shots. 

We made a fresh install of everything yesterday including win 10, got the latest driverns as we installed everything from scratch again. But same molasses like performance. 

Not the newest hardware, but it's within the system req and should have no issues playing back that type of material. Atleast not in the past 2 years. We've even run some of h.265 all-i footage (2K DCI) from my X-T4 without issues on this machine and even 4K 265 all-i.
