Graphics Stuttering during Neverwinter Nights

[erlloyd]

Hi everyone,

I'm trying to run the GOG version of Neverwinter nights on my Macbook Pro using virtualbox and windows 7 ultimate. If I install the game on my Boot Camp partition, everything works fine, but I'm having some graphics issues using the windows 7 guest via virtualbox.

When I first start the game, there is no issue - everything runs smooth and works great. As soon as I save, however, (quick save or regular save) the graphics performance drops significantly (framerate drops, stuttering, etc). The only way to get it back seems to be quitting NWN and restarting it.

I have enabled 3d and 2d acceleration, and installed the Direct3d virtualbox guest extension, but after I save, it's almost like virtualbox is falling back on software rendering.

Does anyone know anything else I can try, or any logs I should look at?

System information:

Host: Macbook Pro, core i7, 8GB RAM, nVidia 330M graphics card, virtualbox 4.2.6 r82870

Guest: Windows 7 ultimate, 2GB RAM, 3d Acceleration, 2d Acceleration, 256MB of graphics card memory.

Games are not designed to run in a VM, and Virtualization products don't try to make games work either, so performance issues after some event would be an expected thing.
As of how to solve it, your guess is as good as mine...
