Autodesk Inventor

[#1]

So I got a new Lenovo W530 this week, with nvidia k2000 gpu., win7 64bit,

running inventor 2013 and setting hardware tab to "quality" i have some unusual behaviour

The model does anti-alias when static but as soon as I move the mouse the anti aliasing disappears. Once the model is zoomed/panned anti aliasing returns.

I've tried to show this on this (poor) video

If I move around with 3D mouse (space explorer) then every think works fine. It's only when mouse cursor moves that anti aliasing breaks.

I've tried 3 different mice and also disconnected everything and tried laptop cursor etc too

I've played with nvidia control panel for ages but those settings seem to have zero impact on inventor,

Does anyone have any advice on where to look to fix this?

Most computers ship with old drivers for the graphics card. The first thing I would do is update the graphics card drivers.

Thanks for the reply,

I did a clean install of windows after getting the PC and updated all the drivers to latest versions, I've also tried an older gpu driver.

W530 has intel hd graphics along with nvidia k2000m discrete

Setting intel gpu in bios only, then inventor actually works fine.

Setting the nvidia gpu only in bios, the same problem recurs.

Try "Compatibility" mode within the Inventor>Applications>Hardware folder.

Gives the same as performance, anti-aliasing off.

"Software graphics" actually makes anti-aliasing work, but poor frame rate performance etc.

You are back to the "Default" settings in the Nvidia control panel?

Hi Blair

Yes settings were back to default in nvidia control panel.

I'm now tried the following

lenovo provided drivers

296.79

296.80

296.88

Also tried nvidia verde 301.42 driver but won't install on the k2000m

I've reverted back to lenovo oem hard disk and factory install, reinstalled inventor etc. Problem still recurs. updated all the drivers again but still no improvement.

I just need to find someone else with a new W530 and see if they have same problem...

Try one of the modified drivers from: http://laptopvideo2go.com/

You may need to used one of their modifed drivers to get the latest/current Nvidia drivers. Used to use this site when I had a Dell Precission laptop as I could only install "Dell" drivers on the machine. By using the modified DLL file you can install the current Nvida drivers.

Had a try and it looks like the k2000m is still to new, I think it's also referred to as 2100m. Either option still isn't listed in the long list of models for the latest 300 series win 7 driver

laptopvideo2go released version 305.53 with a modded inf last week.

This installs without issue on the W530.

The problem still remains though
