I have two graphic "cards" in my notebook: a HD4000 and an nvidia card. Is there any way I can find out which card poser is using for preview? Or change in case it chooses the slower one?

I would guess that it would be using the same card that Windows is using as the display adapter.  In general, unless you have changed your bios settings, your motherboard will "hide" the onboard card if you have another card.  But that's only a "guess".

No not in case of a laptop. By default it chooses the HD4000. Then if you're going to do work that demands more graphic power, it switches to the nvidia card.... at least in theory. Practically it doesn't always work that way. My laptop has a HD3000 and ATI. With most applications, it changes fine, but poser for example keeps on choosing the HD3000. In the end I switched off the HD3000 completely to prevent switching cards and make sure it always picks the right one. Switching is done to preserve power, so if you travel a lot the HD4000 will preserve energy.

I'm not sure which nvidia you have in it, but the HD4000 isn't too bad at all, but I assume the nVidia is better.

I'm hoping you have windows 7 and nVidia works the same as ATI....... If you go to your desktop (no matter which application is running) and right mouse click you get a menu. Top option is the graphical properties and the second one just below you should click (I'm not sure what it's called in english, my windows 7 is dutch). Now you get a window that tells you which graphic card is running at the moment and you should be able to switch cards from there as well.

I've got my laptop set up that it will always choose the better one, no matter what. You can set this through energy management or the grahics options, telling it to always run the high powered gpu.

Hi, thanks for the hints. It pointed me into the right direction. The Nvidia Control Panel can set the preferred card per executable.After I assigned the Nvidia to PoserPro.exe, the preview viewport seems to be much faster. On the other hand, more fan noise :)

You're welcome, more noise means you got the right card. They always work a little different, Ati or nVidia's, but I'm glad you were able to figure it out.

I wish my laptop had the HD4000, it's much better then the HD3000. My desktop has it and it works much smoother then the older versions.

Hm it was OK but when using the poser morph brush, for example, I always had to reduce the preview mode quality to wireframe. Now I have hope that it will be more usable.
