3ds Max 2014 Viewport Display Issues

[jcox]

When viewport is in wireframe mode, after selecting an object, camera or light, everything switches to bounding boxes then switches back to wireframe. When I drag-move an object everything switches to bounding box. This didnt happen in 2013. I had a Quadro FX 4800 with latest drivers. I just installed a Quadro K2000, I still have the same problem. We have 3 other computer with FX4800 and they all have the same problem. It makes it hard to select objects or move objects to another place. I have attached screen captures of this problem.

did you try selecting all objects and turning of backface culling in object properties?

I googled my slow viewport problem and found this thread.  I see it's old but wanted to see if someone found a solution they might share.

I too have a quadro k2000 2gb with my DELL T5600 office computer and tried using the latest 332.76 Quardo drivers and I'm seeing horrible viewport perfomance in both 2014 3ds Max & 2014 Revit.  I stair stepped all the way down to version 331.82 to get a little boost in performance but still not acceptable.

My home computer has an Nvidia GTX 660Ti 3gb card with 334.89 Geforce drivers and its performance is way better, I thought a Quadro workstation card even though a 1gb less of ram would outperform a desktop card in these applications.

To note, I tried the adaptive degradation toggle - no help, unchecking back face cull on all objects - no help.  Any other advice would be appreciated!

We have been experiencing the same issue on our Dell T5600 and 7600 workstations here with Max 2014-15 on a variety of Nvidia cards and drivers.  After some serious testing we discovered a couple of bios settings that seem to make a difference.  The most effective was to disable something called "C States" under the Performance section in the bios.  For some reason this negates most of the lag when using Backface Culling in Max, although it is still there.  

The other thing I have discovered that seems to get rid of the lag completely is to set your Nitrous Driver to use DirectX 9 mode and not DX11.  I'm not talking about using the "Legacy Direct3d" mode, rather "Nitrous Direct3D 9".  I'm not sure what feature you lose other than viewport AA, but it is way smoother with Backface Culling enabled.
