Rhino5 fps problem

Hello everyone.
I have a problem with Rhino5 sr14.I am attaching a video about it.Thanks in advance for your help.

R5 sr14 why underperforming ? everything is the same but R6 is very good performance

Hi @user1213
The display pipeline was rewritten for V6 and is just faster (and more stable) than V5 was. Same goes for the V7 pipeline compared to V6, although V7 does require and newer, faster and better graphics card to perform full throttle.
