Capture One 20 slider lag

[LiE]

I've been testing Capture One 20 Fuji Express the past few days to see if it can replace Lightroom. Overall I'm very impressed but I have a show stopper.

When I'm editing and adjusting the sliders, the changes don't appear until a few seconds after. It isn't instantaneous like in Lightroom which makes it impossible to fine tune. For example as I move the shadows slider the image doesn't change, then when I stop moving it 1 second late the change takes affect. Is this normal? Any settings I can change?

Did you get anywhere with this? I've put Capture One Pro 20 on my Macbook (early 2015 model) and I'm experiencing laggy sliders that isn't fixed by changing the HW acceleration mode. So just wondering if you'd worked it out?

It improved when I got the Blackmagic eGPU but it still wasn’t as instant as Lightroom. So sticking with LR.
