For anyone wondering about the bad pop-in, it seems to be caused by enabling ambient occlusion.
With AO enabled objects in the distance just seem to pop in immediately instead of fading in. It's the combination of AA and AO which causes the pop-in, not AO on its own.
The default AO implementation looks really bad (low res/flickery) so I would have disabled it anyway.
Hopefully someone can figure out a way to inject some better AO without any issues. (I'd rather have no AO than AO which bleeds or disappears at certain angles)
The larger issue for me is performance. I have an overclocked 1070 and the open world seems to jump between 30% and 70% GPU usage at random, when using 1080p with no AA/AO.
2xAA pushes that higher usage up to 90-95% which I assume means that it will drop frames during combat.
The game stutters badly at times when running around the open world. Seems like streaming issues. (off a fast SSD)
And the pre-rendered videos run really poorly. Definitely not running at 30 FPS here.
It probably doesn't matter for anyone using a dual-analog controller, but the input handling seems really bad too.
Aiming has lots of negative acceleration, so slow inputs turn more than fast inputs. That makes touchpad/gyro aiming with a Steam Controller rather unpleasant.
No mixed input support either, so I haven't tested mouse aiming to see if it has similar issues.
There's no analog character movement, only three movement speeds; walking/running, and holding RT to sprint.
The game doesn't remember the state of the right trigger, so if you're sprinting and then pick up an item or run into something that slows you down, you have to release RT and press it again.
That might be fine on a dual-analog controller, but I have that mapped to the outer edge of the touchpad which makes it really annoying.
If you're not familiar with the Steam Controller, it works like this.
Dodging is unreliable with RT on the outer ring, so it also needs to be mapped to a button for that. I can't just hit the outer-ring binding to dodge attacks; that ends up sprinting instead of dodging.
Seems like an okay port at best.
Assuming they sort out the pre-rendered cutscene problems, it's surely a better way to play the game than the console version if your PC is fast enough.
It's just more demanding than you might expect.
