How much performance does TressFX cost?

[shankly1985]

Maybe then perhaps compare The Witcher and Tombraider?? They both use hair animation!!

Then when the next Tombraider is out we can compare it to the older one and see what IQ is like and whether the performance hit is less??

Yeah that's a fair point. I don't have witcher 3 though.

Witcher 3 uses hair effects on monsters as well though so you would have to bench it in scenarios with just Geralt and Lara.

Cheers ladies and gents, results updated.

Side note: I've just used TRESemme - it makes your hair really soft.

I just bought some new shampoo, guess how much it cost me?

You can set it to Geralt only

You based your point on the fact that at 2160p the fps were lower so there was more time between the frames and less opportunities for TressFX to have an effect on the performance.

So I did a run @2160p where the fps was higher than anything anyone else had posted yet the performance hit was still lower than 1080p.

DM you are busted !!!!

Actually it doesn't really change things

Assuming perfect SLI scaling then surely the time taken to render the frame will still be the same under AFR (seeing as one card is still doing one frame)

You just get more FPS on screen at the cost of some display latency.


I am seeing similar results in 1080/2160p (33%/25%)to what has already been posted in both single GPU and SLI. TressFX does look nice but it is a bit glitchy for me in SLI which is a shame as the game is otherwise a great multi GPU title

 

[something daft already!!]

I think Tressfx costs about tree fiddy IIRC.

Actually it does

SLI and AFR are two different things.

Just had another thought regarding TressFX testing.
Can anyone test using Lichdom (which I believe also has TressFX?) to see if the performance hit is the same?

Would also be interested to see how HairWorks compares. What games use HairWorks?

Its does and TressFX in Lichdom is by far the best example of Hair Simulation i have seen yet.

I've not seen it, I saw the dire TrueAudio demos but haven't seen anything else from Lichdom.
Would be interesting to know what the impact is.

Hmm, still not an effect I'd turn on if it cost any performance. I've also not seen Tomb Raider or Witcher 3 with hair effects on to tell how they compare, but if that's the best of them I have to wonder why they bother.

HairWorks in W3 looks like straw, ridged angular straw.
