V7900 2D line AA issue

Hi, I am developing Holomark 2, a benchmark tool for Rhinoceros 5.0.

I have been a longtime nVidia user and have just switched to you, but I can not get good 2D line AA with my card... And I am afraid it is a Rhino-issue or a driver-isse. Can you please shead some light on what could be wrong?

Please look at the images, one is from my dated Vista home machine with a geForce 8800GT card and the other is from my i7 workstation with Win 7 64 bit and the FirePro v7900 with the latest drivers (all drivers have had the same issues)

With this kind of linedrawing it feels like I have sat my screens at the wrong resolution 😐
(And other users have the same issues with both the v7900 and the v5900 and probably other AMD cards too)

Thanks for all help.

can you please try to enable AA in the Catalyst Control Center. This should improve the line quality a lot. Please open the Catalyst Control Center and go to AMD FirePro->3D Application Settings. You will find the Anti Aliasing section. Please try disabling "Use application settings" and select Level x4.

I have tried, It is sat at 8x on the image I sent you.

We have also recently made the switch from older NVIDIA cards to the V7900 and have been very dissapointed with the antialiasing when using Rhino.  Is this issue being looked at to find an improvement?


We will look into this issue and investigate how we can improve the AA line drawing quality with Rhino.


That's good news. I have the same problem in Rhino. I like the power of my new Firepro for dealing with very large meshes and textures, but the AA is a deal breaker. Looking forward to a fix soon.


Have a comparable problem with a w7000 and solidworks in "3D with shaded edges" mode. Comparison between the brandnew firepro and my old quadro fx4800 (both with 8xAA) brings similar results as we can see in holo's images. The difference seems to be the "antialiasing gamma correction" option in the quadro driver. When i switch it off, antialiased edges are looking as "bad" as when i use the firepro....
