Fibermesh - what is that?

And I'm not sure at which point one has problems with them according to their machine specs: I have 16 gigs of ram and a late model Intel quad and I never have any trouble with any Redz hair, body hair, eyelashes, brows and any other combo. The only time my computer slows down at all is when I have an animal in the scene with LAMH fiber hair. Then I have to change the preview to Hidden line or I won't be going anywhere. LOL However, there are no head hair or bodyhair props than even give a hiccup.

Well colour me amazed! I have a pretty beefy i7 with 32 GB of RAM and my viewport slows down considerably when using any high-poly hair. The lag between dragging the slider and actual movement of a limb or rotation of a figure wearing the hair is frustrating. That is true also for smaller body-hair additions though it is all relative to the polygon count. As I said earlier, using fibre hair and the IRay preview together is practically impossible (and yes, I do have an NVidia GPU so rendering is not the issue).

@ChangelingChick : I think you are mistaken about hiding. I've had this conversation a number of times and have always been told that hiding the hair does not speed up the posing. That is also my experience.

Ah, that's the difference. I never use Iray preview. Kills my machine response time too ;). I do it the old fashioned way - change what I want and render to see if it's what I want. LOL

As for moving limbs and such, no it doesn't slow down my machine either. And I've had characters with fibermesh hair, eyebrows, eyelashes, and complete body hair and not had a slowdown.

My settings for the vieport are mimimum possible using the openGL textured preview. And I have mayjor slowdown with fibrehair and clothing being collided and smoothed on characters if I so much as click on a bone. And it's gotten much slower in 4.10 compared to 4.9.

There needs to be a universal master switch that turns all that calculating geomtry adjustment off so one can compose & pose a scene & then when it's done it can be turned on & tested/rendered. Basicsally dForce needs to work as efficiently as cloth physics in Unity. Further, a universal switch for each parent object in a scene that affected all the children would be welcome too.

Well thank you for confirming that I'm not the only one experiencing this. Nevertheless, there has to be a reason why it slows posing for some and not for others. By the way, if I gave the impression that I use the IRay preview for posing, let me correct that - I can't and dont. I only mentioned it because that and fibre hair is a killer combination.

I'm pretty sure it's the smoothing some hairs have on by default that causes the lag in posing sometimes.. I rarely add hair until I'm done posing, draping, done almost all of the surface and light tests, etc so all I have to do is a couple extra spot renders to make sure the hair isn't poking through anywhere or looking weird.

Yes I was moving limbs without any lag.

OpenGL:

Per Pixel Shading: Off

Hardware Anti-Aliasing: On

Display Optimization: Best

I think the last setting is the most important for avoiding lag.

Edit: Some products turn smoothing on by default.

Mine are the same. I'll try a different setting for the Texture quality slider - mine is at Maximum (far right).

I checked for smoothing on the hair I have loaded and there is none. Smoothing is not enabled.

My texture Resources and Pixel Buffer settings are set to the default settings. That means texture quality is about 40% of the slider. I would be surprised if that is what is creating your problems, but you can always try and see.

No, you are right - it made no noticeable difference moving that slider.

Ah well, it's a mystery.

Don't supposed Mesh Smoothing -> Interactive Update is On on anything fit to your figures? Some items have that on by default and is typically the culprit when posing suddenly gets super slow for me.
