Hello all, I have searched the web for a solution to the stuttering of Blood and wine. I have always been able to play a ultra prior to latest patch.
FPS runs from 60 dropping to 18. its unbearable to play, I have played Witcher since it's first version, waited a long time for the dlc come out and now can t play it.

my rig:

CPU: I7 3820 MOBO" Rampage IV Formula, Corsair 16 g ram, GTX 970 Strix, 2 monitors 27" ( both 3d ready)
O/S W10 pro.

I have remove the user and user setting bak but nothing changed, dropped all setting to low, no change.

pretty desperate at this point sine no solution seems to be out there.

any help is appreciated

If you're using GoG downloader then:
Uninstall the whole game, wipe anything witcher 3 from registry.
Reinstall everything except for patch 1.22

1.22 made my cpu temps 10c Higher and lowered my gpu usage/temps so the game ran too hot for the CPU.
I was elated by 1.21 but seriously this1.22 patch is Total Fail!

Thanks for information.

Received a reply from another forum and it worked to perfection and very simple.

Uncheck the "in game overlay" option in GOG Galaxy under settings and voilas no more jagging or stutter
