Does Freecad use GPU?
So quick question.
Does Freecad use or can take advantage of a good GPU on Linux?
I could not find a good answer for this question.

No, it does't use the GPU.Does Freecad use or can take advantage of a good GPU on Linux?

Re: Does Freecad use GPU?
this is very interesting information. can one conclude that when buying a pc, more value should be paid to the clock rate of the processor than to a fast graphics card?
Re: Does Freecad use GPU?
very interesting indeed and rather counter-intuitive to a simpleton like myself
Can you please, possibly point to somewhere where this is explained in more detail?

Re: Does Freecad use GPU?
I'm sure it uses it a little to render the 3d view but that's just not even close to being the bottleneck, it doesn't have fancy lighting stuff or any particle effects so it's lightweight. It's the geometrical operations and tessellation that require heavy computation and those are all done by the CPU. So you don't need powerful graphics for FreeCAD and I think this is true for most other CADs out there too (on the other hand something like onshape doesn't require much CPU because it's all done in their servers so there the graphics might be more important). Also most things in FreeCAD run single threaded so a CPU with better single thread performance should be better than one with more but weaker cores.

I have read this before - so what you really want is "...CPU that has the highest Clock Speed possible..."

Re: Does Freecad use GPU?
OK FreeCAD doesn't, but Coin3D lib does use it right ?
For big 3D models, with a lot of instances and with transparency enabled for eg., a good GPU is an advantage isn't it?

there are quite a few pages out there that discuss our choice with specifically CAD in mind.
The one you quoted is just a general advice?
I am interested since I am thinking about treating myself to a new machine

I have tested the ryzen 3900x and can recommend it
