Lightroom Version: Classic CC

Question or Description of Problem:
Is really slow and unresponsive curves tool a common problem with a new Classic CC?
In my computer (i7-2600K, 16GB, system and caches in SSD, geforce gtx1050ti) the curves act like this short video capture shows: https://www.youtube.com/watch?v=uogKm99ofko

In past versions, the curve tool has been choppy and changes are reflected to the picture after short lag. But now it's really painfullu slow.

Any tips?
 
I’d guess it’s GPU related. The engineers will need to take a look, so post it at the Official Feature Request/Bug Report Forum at Photoshop Family Customer Community

I guess that I found the cause.
I have a lot of tone curve presets in Camera RAW and that slows everything in LR side down. It should not do that but it does :(
 
Oh well done hikari! Make sure you update the bug report with that info so the engineers can figure out a solution.
