gtx 660 anti-alias

[rmerlob]

So, I got a new GTX 660 rig and antialias looks worse on my 1920x1080 monitor than with my gt220m laptop, really looks like a bug, seems to try and anti-alias but when i move the model it gets jagged like in the picture, some artifacts too.

I know these cards aren´t supported but come on if looks okay on a gt220m it should look okay in this one, by the way I got a quadro 600 at work and looks exactly the same as the gt220m though it is faster.

Any suggestions?

Thanks,

RM

Yep, still same problems even with the latest and greatest NVidia drivers on a GTX670 here.

So I've been doing extensive research on the subject, since my last post.

I've decided to go with an ATI Radeon HD 7970 GHz Edition. It performs just below the 7990 and 690 cards, but better than the other 600 series gforces.

I used tomshardware's various graphic card comparisons as a reference. They included Inventor in one of their comparisons.

Also, I've read that the 600 series was just a stripped version of the 500 series cards, making the 580 actually more desireable than the 600's. If you do decide to go with 600's it should be a 680 at the least, but don't expect compatability. The 770 cards are just at the sweet spot for performance. Similar to the HD 7970.

For the record I'm not considering dual GPU options as they only create additional overhead and complexity without much benefit. So SLI/Crossfire is out of the question.

The only reason I'm holding back is furthur reviews of refreshed x79 motherboards that are supporting the 4930k CPU. I'm hoping they stablize the USB 3.0 situation.

Otherwise I'm speccing as follows:

Intel 4930K

Asus PX79 Pro

32 GB Gskill

ATI Radeon HD 7970 GHz Edition

Cooler Master V850

blah blah blah...

You wrote about SLI/Crossfire. As far I know Inventor doest not support this solution. But GTX 690 is dual core itself, I dont think that this is an advantage for Inventor. Does anyone knows something more about 690?

I'm about to choose 4 new computers I dont want to choose bad. Maybe AMD like HD 7970 is what I'm looking for?

Now I'm working on HD 7470 and my AA dont work at all. I've testes Quadro K600 and I bearly can see the difference.

I am working mainly with the Inventor, my assemblies have 2k-5k unique parts, up to 25k occurences. the parts are mostly very simlpe (shwrinkwrap or derived assemblies as bounding boxes). I've stopped dreaming about Quality mode long time ago.

So. I switched to GTX 780 from HD7470 and I must admit that I'm dissapointed.

Anti-alias is working only while I'm rotating model. Does anyone know why?

full spec:

FDSP+PDSU 2014
Intel® Xeon® E5-2620 v2 (6x2GHz)
16GB 1866MHz DDR3 ECC RDIMM
nVidia GTX 780 3GB
240GB SSD + 1 TB HDD

SUCCESS!

I've installed the newest version of nVidia driver, curently it's 332.21. Antialiasing works perfectly.

With previous (attached to the BOX version) 320.11 driver I had problems with AA.

You can mark this post as a solution 🙂

hopefully it solves the issues on my secondary machine too, it was always so annoying seeing it look good for moments at a time then reverting a jaggy mess

I just upgraded my machine to GTX660 and I am having the same problem with anti-alias with Revit. (anti-alias does not work).

Did not have the problem before.

Thanks,
