Better OpenGL performance

[Christiaan]

I realise a 3.06GHz Intel Core 2 Duo with a ATI Radeon HD 2600 Pro 256 MB graphics card isn't a very powerful machine but it can run 3D games like World of Warcraft and Call of Duty no problem.

So why does VW choke and stutter when viewing a small 2 storey house in OpenGL?

It views okay at work on our more powerful machines but what's going to happen when we try to model a large block of flats?

This OpenGL performance problem is something ArchiCAD just doesn't even begin to have, even with very large projects. What is it about VW that makes OpenGL performance so bad?

Neither does Revit, ADT, SketchUp etc.......could the facts have caught up with them after all? Time for 64bit support PERHAPS??!!!!

Have to say even on machine with the following spec you can still detect some lag:

iMac 3.4 GHz Intel Core i7?12 GB RAM?2GB AMD Radeon HD 6970M

ArchiCAD and the like don't need 64bit to avoid this problem. It has to be something about the way VW is built and works in 3D that makes this such a problem.

Yes Christiaan, i have 12GB of Ram too and VW doesn't even look at most of it or the many cores up for grabs.

VW only seems to make use of a very small percentage of these or the Graphics card but the SSD has made an improvement to most aspects. Still not the whizz i had hoped for.
