So, finally got to see some TXAA in action, not some pixelated compressed Youtube video, but actual game play.
This is definitely going to be one of those subjective things. The blur is very visible, and when moving it is almost like a motion blur (no, not excessive blur like in some games where you turn and everything is out of focus.)
If I had to describe it, it reminds me of back in the day when HDR was all the rage and blooming was every where, jaggies were masked by light sources.
This doesn't affect the light but the edges look...fuzzy. Not jagged, but also not smooth (does that make sense?) I'd even say ghosting, but that would be too strong of a descriptor.
Not sure if it's our settings or not, but the game felt less smooth with TXAA vs FXAA. Sort of goes back to that fuzzy/ghosting/spacey vibe I was trying to describe.
All in all, a decent new feature, if you like it, and quiet impressed with how it handles crawlies, just wish it didn't have a dream feel to it, and for the love of God don't stop moving or the blur will consume you (the blur when not in motion is really really REALLY bad.)
EDIT: Dream sequence - it gives me a vibe like a dream sequence in a movie. The edges are a tad fuzzy but that's probably the blur in motion (who ever says blur is gone when in motion is lying.) Like hazy. But even that is too strong, you'd have to see it person. GOing from No AA to FXAA to TXAAx4 is like getting drowsy, that's the best I can do right now to describe it.
