i assume isfet means the undub patch? someone did a nice longplay of it here:
if they don’t mean this, then they’re likely confusing it with the recent drakengard 3 patch, which got it running at 60 fps, though with all due respect i don’t understand why anyone would want to play drakengard 3 in the first place and if they did it feels like it would defeat the point to do so as anything other than a slideshow.
