Graphics lags when having sketch turned on. Inventor 2014

[lch]

Hi.

Im using Inventor 2014 SP1 on a HP Z620 with 2 CPU - 16GB Ram.

Graphic card is a AMD Firepro W7000 4GB.

When i am rotating a big assembly 500+ it doesnt lag that much, but when i have a sketch turned on at the same time, the graphic lags extremely when rotating.

I have tried all the recommended drivers and the newest drivers and nothing changes.

I tried different hardware settings in inventor (Performance, Compability, Quality) and there is no difference.

I also tried to change the graphic Card with a Nvidia GTX 660.

It rotates much better (smooth) in big Assy than my firepro but it is having the same issue when having a sketch turned on.

Do you have any input on this issue?

Lars.

I inquired about this issue over a year ago but received no reply:

It seems almost as if Inventor does not use the graphics card at all for sketch geometry but instead does it all through the CPU. Unfortunately, since no one from Autodesk responded to my post, I couldn't confirm whether this is true. Whatever the cause is, it makes for frustratingly slow sketch performance.

I wish I had a better answer for you at this time.  We're aware of this issue and our graphics developers are working to improve it.  I don't have an ETA at this time.  I've asked the development team if there are any suggestions I can provide which might offer immediate help.  If they do suggest something I'll let you know.
