It seems my GTX670 is not compatible with open GL in Vue and Im having to use the software option. Am I losing much in performance? Studio 2014 is like treacle sometimes. Is there anything I can do to rectify the open GL problem. Ive got the latest drivers, have unticked background draw and use wireframe.
My other specs are;

Win7
Intel i73770
16gb ram

No hardware openGL mode is compatible, or just the "shader 4 " will not work?  The only performance loss really is in the User Interface, renders will be very close to the same on a fast system.  I believe only anti-aliasing is the only render task that can be passed to teh GPU and it needs to be enabled, only in Vue 11 or later.

 Thanks dreamcutter. No, only the software mode is available but if you say Im not losing much Ill stop worrying about it. Renders aren't too slow, it`s the actual positioning of the objects that takes forever.

Tnats expected however something isnt right.  That is a popular GPU and it should work fine. If you are using Windows default GeForce drivers try the Geforce/com factory drivers  - or the other way around.  You should see no conflicts or hardware errors in the Windows device manager.
