Hi all I've read a fair bit about Premiere 2019's choppy playback issues but i wanted to get an experienced user's advice on what i should reasonably expect performance wise from my new machine as I'm relatively new to Premiere? My new machine is an i9-9900k (Asus Z390 Prime-A Motherboard) with 32GB RAM. My 4K Premiere pro project is coming from a Samsung 970 EVO NVme. My media cache and proxies are also coming from the Samsung 970. I've create a bunch of 2 camera multicams shot at 4K 25fps. I've imported these to a 1080p 25fps sequence to match the final intended output. I've created proxies of the 4K at 1080p. When i playback at full resolution with mult-camera view disabled, with or without proxies enabled - i get dropped frames. My cpu is running at ~55% at this time - regardless of proxies or not. At 1/2 resolution cpu drops to 30% and the problems appear resolved, however adding just 1 or 2 lumetri moves loads the cpu up to 100% and it drops out unbearably. Dropping to 1/4 resolution helps but then any changes in lumetri and it gets messy again. The 970 drive is running at 0-1%. I appreciate that the 4K footage is being scaled to 50% to fit the 1080p sequence which must cost some processing overhead, but should i really be experiencing such bad performance for this spec of machine? I find it hard to believe that i can't add any effects without it becoming a horrible experience, but i'm not sure where the bottle neck is... I've tried a a bunch of things to improve on matters including audio settings, proxies, high quality off etc but nothing seems to make a difference. If anyone can advise it would be greatly appreciated - it would be nice to know that i've not just wasted the £1500+ spent in order to get this job done! Or maybe i should just try Da Vinci?!?
