Hello Michael.

I repeated the test with the huge "engine" model, on my Desktop PC.

Windows 10 64Bit Pro Eng
i7-7700K 4 cores/8 Threads 4.5 Ghz (running at constant 4.45 Ghz)
32 GB DDR4 at 3000 Mhz (dual channel)
SDD NVME M2 Samsung Evo 500 GB
Overclocked Nvidia Gtx 1080 Ti (11 TFLOPS in FP32 and 11 GB GDDR5X RAM)

First of all i want to tell you that your overall job for this v4 is amazing!! Thanks a lot for your constant efforts.
And I'm aware that this in only the very first beta :)

With that said, Michael please consider these following considerations only from the point of view of someone who wants help you in developing an even better Moi.

These tests took me a long time to be completed so please Michael check this summary report and its detailed part :)

At the end of the day these are my final considerations :

1) Load time can be acceptable although I still consider it a bit too long
(Same model in Rhino V6 WIP is loaded and displayed in 1 min and 20 secs!!)
2) Exporting time is good
3) Memory usage is good
4) Memory releasing on exit is excellent
5) Viewport performance : I have to be honest. Actually I'm a little bit disappointed by the viewport performance of this V4 beta.
It's really too slow, above all if I consider that I'm running Moi on an overclocked Gtx 1080 Ti equipped with 11 (!!) Gb of super fast VRam,
that although is not a high-end Quadro P6000, it still the most powerful Graphic Card on the market.
Moi's viewport performance are very weak when compared to the smoothness of the viewport of Rhino V6.

And this is the detailed report :

Thanks a lot and have a nice day :)

I stay tuned.
