Units fading in and out of the fog of war looks a bit messy, and is handled cleaner IMO in other games - including the Infinity Engine games. The bright ring on the edge of the FoW also doesn't look very good/looks unnatural when moving.

 

Here is a PE Demonstration

 

 

Here is a BG2 Demonstration

 

 

BG2 handles it a little bit cleaner IMO by doing a full instant fade of obscured units, although it's delayed slightly after the FoW covers them.

Here's how Warcraft 3 handles it

 

 

The unit fades instantly, the FoW fades shortly after.

 

IMO the best way would be to have the unit and FoW fade at around about if not the same time, maybe fading the unit instantly after their whole selection circle has been obscured ?

I think I prefer the way PoE does it to the Infinity engine games.

None of them handle it perfectly, the best way IMO would be for units to instantly disappear once their selection circle is no longer visible. The fading just looks bad.

I agree that none of them are perfect, but I actually disagree about the fade looking bad.  I feel like the fade makes it less visually disturbing than having character model instantly appear.
