Hi,

I am continuing this rather older thread, almost six years past since last post and sytsems available have again been developed.

I come to the edge with my notebook and PC from 2012 when making more complex models in MOI or loading vectorized pdfs or other formats. Working in MOI with such complex things make it start stuttering and selecting lines is with a delay of one or two seconds which is zero delay at simple models.

I think that with a new system it could run smooth. The question is, is a "gaming pc/notebook" the key or a "cad pc/notebook". I read that softwares use sometimes only one core and other use multicores, where latter the amount of cores is relevant and not the frequency.

Nvidia RTX A .... ? This is mentioned when reading about dedicated CAD systems. AMD has the counterpart RX I think.

Any idea what to do? I don't want to invest in a new system loaded with best graphics and CPU and RAM and then I am again with stutters, just because it's not the sytsem for such graphic / 3D moeling works.



Thanks,
Axel

Hi Axel, re: "gaming pc/notebook" or a "cad pc/notebook"

Either should be fine but the CAD marketed one will be a much smaller market and will have a much, much higher markup and cost, with little actual benefit.

So I'd recommend targeting a gaming oriented system.

It would not hurt to look at a CAD workstation but I wouldn't be surprised if you would be seeing like 3x the cost.

Hi Michael,

thanks for your reply and advise. There are indeed "CAD solutions" by famous notebook and PC makers and these are definetly aimed for large companies with same budgets.

But there are also very similar prices for gaming and CAD software use. The difference is the graphic card. There are those cards for gaming purposes and those made for CAD, I even just recently learnt about these CAD graphic cards.

I thought MOI has better performance on such dedicated CAD graphics and certain CPU types.



Best regards,

Hi Axel,

re:

Well that's what the graphics card companies want you to think but no it's not really the case.

The GPU vendors have special "CAD" editions but usually the "CAD" hardware is exactly the same as the "Gaming" hardware and the main difference (aside from a much higher price) is that they give you a better quality OpenGL driver on the CAD version.

That's why MOI doesn't use OpenGL by default for Windows.

By default MOI uses the Direct3D interface that is also used by most games. The GPU vendors don't play this "intentionally poor driver" upsell tactic with the Direct3D drivers.

If you are going to be using other CAD programs that do use OpenGL then it may be helpful to get the CAD version.

Hi Michael,

thanks for clarifying that. It's really helpful for my decision.
