I just thought of a potential bottleneck, as I brought up cooling in an earlier post.

There are two types of fan cooling for GPUs. The basic fan type, and the blower-fan type.

The basic fan type requires that your computer case have good fans and ventilation built into it, as the heat is dispersed into the computer case. The blower type is enclosed in a housing that has a fan at one end (odd-looking fan) that blows air through the enclosed housing and out the end of the card. That blows the hot air out behind your computer. Pretty much any pre-built computer you get will have the blower type. If you have a small or crowded case, you should also get the blower type.

I've been watching my GPU temps and they seem fine, I have iC6 and 3DX running now and this is the report from the "HWiNFO64 Program"



Dell XPS 8900, Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz, 3408 Mhz, 4 Core(s), 8 Logical Processor(s), 16 GB RAM, - 4 GB GeForce GTX 745, NVIDIA compatible.

@Snarp Farkle: Make sure focus is on iClone when you monitor, because that is when the GPU starts working. Looking at the clock speed of your card it is in idle mode. it would also be good to check CPU temperatures.

Another thought: what is your power supply rating? Dell is probably OK, but I used to have an HP that had a low quality power supply that I had to replace.

EDIT: I just downloaded the tool and noticed that if you run iClone with a sizeable project and take the values in the Maximum column, you'll get a pretty good idea of the load and temperatures.

This is what I got while running the Abandoned House project in loop mode.



I looked on the Dell site and found that it has a 460W power supply.  PWA INTEGRATED, 460W, POWER FACTOR CORRECTION, whatever that means lol.

I went here: http://www.coolermaster.com/power-supply-calculator/ to check the needed power supply, and 275 Watt is recommended so you have plenty extra.

Also, everything looks fine under load, so your system doesn't seem to be the problem.

Thanks animagic for looking into this, it's good to know the system is as adequate as I thought it was when buying it, so at least that's one thing out of the way. 
Now on to see if the problem is software related, I've tried so many things now my mind is like rice pudding! :crazy:

Would faster SSD's help prevent frame drop during live link animation to UE4? For example, when I try to record the incoming live link face capture stream I'm missing frames. How can I increase performance of the UE4 sequencer recording from the iClone Live Link animation stream?
