Still a bit of work to do on performance in handheld. The framerate is fairly close to target throughout but there's some frequent stutter problems. The docked gameplay CD Projekt Red showed off doesn't have the stutter. I'm betting this is a bit further from final than docked. This is backed up by their presentation a few days ago where they said they had been recently testing handheld. I'll be following this with interest, if they can smooth out the stuttering it will make for a pretty darn impressive handheld showing.
Edit: Also, other off screen footage of handheld gameplay lacks the stutter so some of it may be the video or recording method.
