Missing Antialiasing

BriHecato — Mon, 02 Feb 2015 13:30:52 GMT

I cannot turn on "Antialiasing" in 3D presentation (part or assembly).

Config: Dell Precision T3500 with Xeon W3690 / NVidia Quadro FX 4800 / 12GB Ram / 2x FullHD screens

NVidia Drivers: 307.45

Inventor: HSM 2015

Hardware set to Quality.

Display Quality set to "smoother".

Visual style changes - nothing.

In NVidia panel:

User preference to Quality (nope)

Manually set Advanced settings (Inventor found by the drivers) to 2xAA, 4xAA and other types - nothing ..

What else can I do ?

Or it is limitation of Inventor version (HSM edition)?
Or This quadro and drivers are not good enough for 2015?

I was having problems too..

First.. set all nvidia settings back to default.. Once Inventor starts working you do not need to do anything outside of Inventor to get it to work.

Then see this..

Fairly sure that running the inventor reset utility then switching to quality/software graphics then restart Inventor.. Then turn off software graphics and see if that causes the anti-aliasing to work again..

Something has just gotten confused/corrupt (I think its because I was playing with the nvidia settings too for a while)

Thanks for reply

I set Nvidia settings like eljoseppho, and it's almost what I expect.

"Defaulting" and software graphics on-off doesn't work.

Ordinary Radeon 7770 with previous Inventor 2014 work much better - only Inventor "smoother quality" settings.

I'm fairly sure the inventorreset utility plus the on-off is what did it for me..

Not just the on-off..

But if you are good then thats all that matters.
