Does anyone own a machine that screams in 2D?

Anonymous — Wed, 20 Jun 2007 14:40:19 GMT

I have lag on all my machines in 2D to some extent. AC11 has pushed things slower yet.

I am re-evaluating my set ups and wondering if anyone that uses AC10 or AC11 all day has a machine that moves in real time with your clicks and pans. Especially in layouts where it seems the slowdowns are the worst (and yes, I have auto updates off)

I am planning on either building a machine from scratch or even switching back to mac platform. Desperate to have my 2d navigation get back to the speed I had in AC9.

My newest machine should be able to fly but it doesn't. Flies in all other 2d intensive apps (photoshop). Graphisoft is trying to help me figure out where the problem is.

So I was hoping to get a list of successful processors so that if I build a machine I am going to be successful.

Thanks much

Greg,

When was the last time you updated your Nvidia driver? I have almost the same specs as you (3.6 mHz P4 and NVidia 7900GTX), and updated the video driver a few days ago. Made a HUGE difference in AC11. Previously, I had a fairly recent video driver, so I was skeptical about the need to update it.

One of our forum colleagues reported that two graphics cards worked together to make 3D OpenGL navigating faster. I think it was 1Gb in total.

I wonder if combining cards can speed 2D redraw?

Richard,
I just checked and I do have the most recent driver installed. I have been checking regularly. I even tried installing nvidia's newest 8800 card w/ 640mb of memory but did nothing in 2D.

Thanks

I have one that screams about 2D, does that count?

Ha. I know the feeling.

You might check the NVidia settings and check to make sure that the Anti-Aliasing is set to "Application Controlled".

I have that adjusted. Have tried turning it off as well.

A setting that does help a bit is turn the color to 16 bit as opposed to 32 bit. Speeds up a bit, actually maybe as much as a third.

Still unbearably laggy though. My older, single processor machine is much faster. Slow, but bearable.

Thats why I am wondering if people are having luck with the new core duos. Maybe just an overclocked single processor with a good graphics card is a better solution w/ archicad. I keep feeling that it is my processor that isn't liking Archicad. It runs @ 50% at rest when Archicad is open.

I have had a strange thing happen.

Discovered that if I open up a one gig photoshop file and then open my archicad file my cpu usage goes to a normal 1-50%, 1% at rest.
Archicad works much better. When I close the photoshop file archicad goes to the dogs again and my cpu usage goes to above 50% and usually is hovering closer to 100%.
Somehow, photoshop is forcing Archicad to be less demanding of the cpu... Maybe forcing it to use the video card? Any thoughts on what is going on. Wish I knew someone using the same CPU as me to see if the problem is there.

Weirdest workaround I have come up with for Archicad yet.

And if I stand next to the aerials and hold them just this way, a little to the left... no, a little to the right...

This thread just helped me solve an issue that was driving me NUTS, and thought I should bump this thread in case anyone else is having the same problem:
Recently installed AC 11 EDU on a machine with an ATI Radeon, and OpenGL was running like a dream but the 2d redraw was incredibly slow - turn off anti-aliasing and such like in graphics cards settings (or turn to "application settings") and 2d now works in realtime.

You have several options with Archicad to improve 2D performance:

1: User Preference>More Options: simplified model - reduces demand on the card to image 2D elements.

2: The was a way to turn off the graphics card 2D acceleration if there was a problem with it but I cannot find it in Archicad 11. Clarification, here?

Found out that closing views, 3d, elevations etc with the red x is not really
closing them.
My machine bogged on 2d panning a lot after I had been working with a file for a while, until I found out about really closing views with ctr W.
Without closing using ctl w, you could be getting slower and slower responses even lock up, the longer you have AC open and working around the file.
Check under AC's Window to see how many "views" are really open.
Even having saved a file with lots of views still open could cause the file
to go slow right after opening it.
