HP Pavilion dv7-6b76eoi7 2670QM 2.2 GH, 6MB L3 CacheChipset - Intel HM65 Express1TB SATA 5400RPM8GB RAM DDR3 1333MhzSwitchable Graphics between: 

The on-board Intel® HD Graphics 3000, which is just for power-saving purposes

and the discrete GPU, which is meant for things like Revit - AMD Radeon HD 6770M 2gb GDDR5

I am running Revit Architecture 2012 x64.

The GPU has a feature called PowerPlay (hereinafter PP). It's a pretty annoying feature as it causes my notebook to experience Black Screen of Death and to freeze now and then while watching movies or while in a video call. So I just disabled the feature and the problems seemed to have gone away until I started up Revit and eventually found out it was unable to utilize Hardware Acceleration, thus it worked crappy. Once I enabled PowerPlay again Revit worked smooth again cos it was obviously taking advantage of Hardware Acceleration (hereinafter HA). Up until that moment I hadn't changed anything in Revit and it was by default having HA turned on. So the possible combinations I got are as follows:

PP enabled + Revit HA enabled = Revit working smoothPP enabled + Revit HA disabled = Revit working smooth (somehow? though disabling HC would make it work bad)

PP disabled + Revit HA enabled = Revit working really bad (???)PP disabled + Revit HA disabled = Revit working smooth (???)

So does this make any sense to anyone? Could anyone explain how enabling and disabling HA affects Revit, because what I expected was that disabling it would make Revit work bad, but apparently it didn't. How is Revit able to work smooth when I turned off HA? I though HA means that the hardware boosts up the performance of the software, What happens in the case when HA is disabled and why does it not have any negative effect in my case?

Sorry! Shift+Enter apparently didn’t work well.

I dont know alot about effects of HA. But Revit should basically run fine if HA is on or off. Depending on your graphics card you should get better performace if HA is on when working in 3d with large models. there are certain Revit features like Photo Realistic display that only work when Ha is on.

Thanks! It seems, though, that it works just fine for me even in 3D, even in Realistic type view.
