real view, occlusion, shadows: sometimes you do not - why?

[reggio]

Hey, guys.
I have certified nvidia card, but I happen that in certain assemblies I can choose whether to activate real view, occlusion, shadows while other times not... :

In this case, for example, in general I cannot select anything (except for perspective) instead in its sub-assistances I can activate everything ...
Can you tell me why and how to fix it?

depends on the complexity of the assemblies. he calculates that he cannot because he exceeds his memory and does not enable it.
then it seems to me that it depends even if you have weight solved or not.
If you don't have to make some pictures a little more bellina doesn't need anything.

hello and thanks, I remembered something about the weight solved, but that should be fine but it still doesn't allow me to activate anything...

In fact, I only need it for aesthetic issues: send images to customer

for the memory speech can I intervene somehow to "shake it"?

Can the display be in the presence of large axioms or not?
to which number of parts did you associate the automatic switch to the display large assemblies?

Hi, then I would say I've solved even if
sw says that big assemblies is activated - I have ever set it active
... in any way carrying light weight (which was not active or was solved) from 500 to 700 (with 640 parts together), closed and reopened together and solved ...

I do not know any difference of sort of speed from 500 to 700 so I will leave it so and to the next problematic group I will raise it again qb enough ... I just hope to remember this post and find it again without asking for help;-p

thanks to all for the inevitable support
