Overall, or at least in the same area as the old Alpha (such as the village) I get better performance, and can move from a preset of Medium, to a preset of High and keep the fps I was getting in 0.3. But, moving into some new sections and especially the camp I get some major (sub 20fps) drops, which I guess are linked to AI rather than rendering. Dropping back to lower settings does not help, so it seems at this point the AI is a huge bottleneck, even with a few characters on screen. It seems that to allow large numbers of active NPCs the devs are going to need to perform some major optimisations to make this game work.
My PC is not a powerhouse (i5 2500k@4.4 – 8GB 1600mhz RAM – GTX670) but my reference points, such as other CryEngine games, and other RPG’s such as Witcher3, show that there is some serious work needed to make this playable when introducing large scale AI… something I’m sure WH will address.
