asus n55sf laptop viewport problem in 3ds max 2012

[erkutacar]

hi i just bought a brand new asus n55sf laptop and it has 2gb gt555m card but it also (for some weird reason) has intel hd video card too. and if i disable intel card it also disables the nvidia card. so both must be activated.

 

now the problem is the viewport performance is extremely poor. i can only work in wireframe and even that works slow but!, max actually uses the gt555 card because iray sees 1 cuda device and renders properly.

 

if i switch to shaded view or even flat view viewports freeze. program doesnt crash but i cant navigate the viewports..

 

btw im using the latest drivers.

system:

i7 2670QM

8gb ram

2gb geforce gt555m

win7 home pr x64

3ds max 2012

update: ive tried the same file on a very similar asus laptop and it works fine.. so what could be the problem with my laptop?

Does Asus have any driver updates available? The Intel/nVidia thing is called Optimus. It will switch between video cards depending on what you're doing. If it's somehow become confused it could be trying to use the wrong video card - though I don't have personal experience with whether this will happen in Max on a laptop like that. You can force it to use the nVidia card when in Max - the instructions here: http://netbooknetwork.net/2010/force-nvidia-processor-on-specific-programs-for-laptops-with-nvidia-optimus/ should cover it.

99% chance it's not Asus's fault. It's nvidia, Microsoft and Autodesk products mucking things up.
