Hi - First of all I have read all the post's about IClone's Lagging Viewport's and I have tried all of the common replies such as: update video drivers ( although I know that nearly all of NVidia driver updates are geared towards the latest game releases ) I have a GTX 1080, so I have 8GB VRam.
a i7-6850k, 32GB Ram and I also use 3DS Max 2017, Motionbuilder 2017, ZBrush, Adobe Premiere for video effects, and ALL these programs run smooth as butter and very quick and responsive as they should on this system. I am very pleased with the performance of all of them. Then I fire up IClone which I might add I bought 6 months ago and have probably used for <15 hrs. Because every time I start playing around with it, the da#m program crashes way to often, but what really drives me crazy is how unresponsive the program is: The viewport lag is HORRIBLE. I can load a single character, turn off every lighting effect, It show's I am using only .6 to .9 GB of VRam! and The viewport when I rotate will lag and freeze for 1-3 seconds then resume..... It also has this effect when simply panning. all this is while using " QuickMode" And it is not just the Viewport, when I click menu items - It will also hesitate before letting me select a item ( On the top row pull downs )  It is so bad I just shut it down and keep hoping some update will fix this. I am open to anyone with Good idea's how to FIX for this. Does anyone know if this viewport is OpenGL or just what Graphics functions it utilizes? There are absolutely so graphics video settings IE: driver selection, mode, ect in the program.  Thanks ahead for reading and I hope for some response - the last post I posted about FBX export problems got 1.3 thousand views and not a single response... and the Technical support from IClone leaves A LOT to be desired. ( But that is of course my opinion ) THANKS

That's really weird.  I'm sure you've already tried this, but have you completely uninstalled iClone and then reinstalled?  That would be the minimum I would do to begin with.

I'd also, if possible, run from an SSD rather than a mechanical drive.  iClone isn't very good at managing disk resources, and nearly all of us have noticed huge improvements when changing to SSDs (I've always run my OS on a small SSD, but I never got iClone working *really* well until I installed my 2TB SSD and installed ALL my iClone content and such on it.  Now it's lightning fast).  Still, one character in your scene shouldn't cause issues -- running Win 10 with all the latest patches?\

(And as for video drivers -- I'm using the 1080 with drivers from last March.  As you correctly note, most updates are for games, and I found later drivers screwed up iClone considerably).

If you uninstall, run a registry cleaner, CC Cleaner, and then delete the temp folder(s) at:

Thanks for the reply Kellytoons ( I note that you are active in replies on these here Forums )
I have re-installed IClone7 on 2 different occasions to no avail in regards to this problem. It is installed ( as well as the content directories ) and runs from 500GB Samsung SSD.
( In fact it is the only 3D Program that loads from the SSD ) all my other programs perform fine loading from a 4TB WD Black. They gain no advantage from the ssd other than loading speed ) I do load content from the ssd however.. ( projects, video, ect )  I have win10 with all the updates - EXCEPT KB4056842 - the Intel security patch - I am not convinced they have fixed anything yet, and I read of a lot of Re-Boot problems with all processors not just the Broadwell that I have - I had to uninstall that patch when it installed itself - it wouldn't allow my ASUS -  I have a X99 Deluxe 2 MB -  and it killed the ASUS AI Suite ( The Bios Interface ) Asus have fixed that issue with a update, but I am staying away from BIOs updates and patches for that problem - It is minimal security risk for me as that system ( I have 2 and a laptop ) is seldom ever on-line. Anyway I have steered away from the topic here a bit...  I have NVidia driver 388.0 ( Oct/2017) installed currently. One thing I have not tried is installing IClone on my Game/media system ( i7-7700k, 16GB Ram and a gtx1070 ) and see if any difference. That system gets regular NVidia updates because of the game use. But, I'd really prefer not to have to do that, but I may have to try cause I cannot use it as it runs know on my 3D System. Anyway, thanks so much for the quick reply. ~ Dave

I have found that iclone suffers in performance if you don't have your energy settings set at high performance, if it is on something else you tend to loose frames when playing back. This setting affects the processor clock, and i have noticed some performance issues occur when panning for example if set to balanced power mode, this doesn't fit all the issues you described but it is worth a try. On the meltdown/spectre patch i can confirm no issues at all on  a core i7 4930K, this patch does affect performance but only very specific tasks which normally do not apply to regular computer use, it did kill my AI suite. So far all media creation behaves as usual on my system ie iclone, my daw cubase pro, hitfilm, video conversion etc don't seem to mind the kernel patches.

Something else you could try is resetting the nvidia control panel preferences for 3d applications.

Dave,

(Some would say I'm way TOO active in replies here :>)  So you have iClone installed on an SSD but everything else is on your WD drive?  Is that your C: drive?  If you changed iClone's default settings (which default to the C: drive) in any way I think I'd at least ONE MORE TIME try uninstalling (as Rampa says, make sure you clean everything up afterwards before the reinstall) and then install to all the defaults and see what happens.  Unless you've changed something it's VERY odd that everything else you have runs fine but everything else you have runs off a different drive -- that tells me the drive itself is the issue.

So, conversely, if that SSD IS your C: drive (and you were allowing iClone to install to the defaults) then change things and install to that WD drive.  IOW, you want to minimize the variables, and at least one variable you've outlined: all programs that run correctly run off another drive.  So for sure you need to follow that path whether it makes sense to you or not.

Something is definitely amiss.  Based on your system specs, you should get much, much better behavior.

For a quick apples-to-apples test, can you open up a couple of "sample projects" that ship with iClone 7, please, and see if they perform okay?  That will help eliminate a lot of potential variables.

Also, consider installing something like "GPU-Z" which is a free graphics card monitoring utility.  It will tell you how much VRAM is being used and how busy the GPU is.

There are a lot of assumptions being made with regard to what scene you are creating, and under what conditions you are operating under.
Is it optimum?
Because one avatar with high resolution hair all by itself can sink iClone into a sputter.
Also, do you have any other applications open, etc...

You have to Benchmark it yourself vs an actual step-by-step comparison, and see where the breakdown lies.
I recommend this:

(1) Open up a blank scene and
(2) follow one of the online tutorials put up by RL for iClone 7, EXACTLY, and
(3) see/mark where the speed behaviour difference begins to occur, and note if the RL tutorial also had this speed issue.

Take that and send to RL support, or show to the forum. 
Either way, make it as detailed and specific as possible.

(ie - at 0:45 in the tutorial, the instructor navigates his UI without any loss in speed, but on my UI, I see (x) behaviour.)

Good Luck!  

Thanks for the reply's
Yes, IClone is installed on the default C Drive with all defaults. There are no other problems related to that SSD. It is a year Old Samsung EVO 500GB - Win10 runs and performs very quick and snappy on that drive. 
I am using as reference The IClone Character "Zane" nothing else in the scene. It displays it is utilizing 1.5 GB VRam. ALL light Effects are off.
No IBL/HDRI, No Effects, No Shadows, No AO, No Physics -  No anything that you might think would cause the Screen Lag. When I find time I am going to install it on my other Game/Media system ( Specs noted in another post ) just to check it out. It stumps me because every other program I have ( 3DSMax, Adobe, Keyshot, all them that have a similar viewport perform without any flaw - like butter. 
If I knew how to do screen recording I would and send that to IClone/post it here. ( Perhaps I should learn how to do this )
Also all the NVidia 3D settings ( NV Control Dialog ) are set correctly for this program - actually all are set to defaults - so no added overhead there. The system is set in Performance ( Power settings )
Thanks for the replies.
