Hi All
I’ve stopped playing KC:D around february/march becuase of massive amount of bugs and low fps.
Just wondering is it worth to start playing again or should I wait a bit longer ?
Thanks
Most bugs are fixed (but not all).
The game is still very demanding (performance). You will not get so much FPS like in Witcher3.
But many people love the gameplay(beside savesystem, lockpicking and combat). 
Give it a try. Start a new game.
I haven’t experienced game breaking bugs since the latest patches, just some minor bugs like open doors that can be unlocked in Rattay, ugly rain, some combat unresposiveness…
In terms of performance there have been very little progress, at least on standar PS4, but I know it’s a very demanding game.
I still love the game, the beauty, the quests, give it a try.
There are minor bugs, the fps issue bothers some, not an issue for me. The last patch changed some things, some not for the better but not bad either.
If on PC the mod situation has gotten worse. and for me the side to side shake when turning has crept back with 1,6 ( amd pc with XB!1 wireless controller but affect my mouse too.)
You may have do a clean re-install. I would wait until the next patch update with the DLC.
