Graphics/program performance

[0502880]

Hello,

I have encountered a couople of time a strange behaviour of orbiting the view. Especially it occurs with use of 3DConnexion CAD mouse (I have the newest drivers). And it seems, that it's related to model/file size. The mumber of sketchches seems also to be some factor.

I've takaen off all view effects and I in preferences I have chosen simple display and better performance. I have also chosen limit effects when graphics memory is low. I have to use DirectX 9 driver because of my render software.

Is the problem in my modest hardware (NVIDIA Quadro FX 4800, Intel Core Quad 2,66GHz, 8Gt RAM) or is it more related to Fusion 360 performance?

What behavior are you seeing?  I just got an older space explorer myself and have been noticing some odd behavior too.  What I'm seeing is that sometimes for no apparent reason orbiting is either slow/jittery or has a significant lag.  But then suddenly it will go back to normal.

I also have a faster computer (but not by a lot).

It's very likely due to the graphics card. Look at my reply in this thread.

Hmm, that would be unfortunate as I have a Firepro v4800.  A gaming card is not really an option either since I also use Solidworks.

I'm not totally convinced it's a graphics problem though.  I didn't notice the same issues when using just a trackball.  Next time it happens I'll have to see if it makes a difference which one is used.

There may be certainly some influence of the 3D Mouse but the main problem is the graphics card. Actually, not the card but the fact that for these "professional" graphics cards the DirectX drivers are not optimized and fine as long as they work. All of the optimization goes into teh "certified" OpenGL driver.

For comparison, I use a 3D Connexion Space Navigaror on a 27" iMac from mid 2010 with an ATI Radeon HD 5750 1024 MB. Thats a mobile/notebook graphics card.

DirectX does not exist on OSX and until most recently Apple's only API to 3D applications was OpenGL and Apples implementation was not the best.

However, with all graphics effects disabled except antialiasing, navigation with the 3D Mouse is buttery smooth. I only have to turn of antialiasing with the monster T-Spline in my most recent project due to too little graphics memory, but that's it.
