VRAY 3.50.01 quad viewport performance issue

[walee]

i've just installed the vray 3.50.01beta and it has broken my viewport in 3DSMAX 2017.
Let me explain. I'm starting max with an empty scene.
If i'm using a single viewport layout. No problem. i can move and rotate the viewport camera and i get around 400FPS (i've juste created a single box)
if i switch to a quad viewport layout, when orbiting around my box i get aroung 6 FPS. Moving around the object is getting so slugging, and the only solution to get a better framerate is to disable to other 3 views (it's then like working in a single viewport layout).

i've uninstalled vray 3.50.01beta and i don't have this problem anymore.

i've also reverted to 3.40.03 and everything is working alright.

What could possibly be the cause of this problem ?

i'm running windows 10 pro 64bit with the latest updates.
i'm running with the lastet nvidia drivers 376.33
CPU is i7-6850K
64Gb fo ram
3 X 1080GTX
3 Monitor with a resolution of 2560x1440

Hi,

I'm not aware of any view-port issues with this build and can't replicate this low FPS in my quick tests. Would it be possible to install and try the beta again ?
Do you use any custom presets or max start-up file? Have you tried to switch between Realistic and Shaded view-port to see if there is any difference?
