v.11 Problem

[Anonymous]

hello there
i have a problem with v.11.
i m using it for 1 week now and it goes very very slow
while v.10 was faster and of course v.9 faster than v.10 but this thing with v.11 is unbearable. i cannot work any project with furniture and equipment on. but even if it is off it's not going so much faster.
i already ordered 1GB extra RAM ( i now have 1GB) and i was wondering
is this problem going to be solved?

thanks a lot

The only significant difference I can think of is that AC 11 now uses DirectX display technology for some of the 2D feedback effects. If your video card supports DirectX, but does not do it very well, that might cause such problems. Try to update your video card driver, maybe that helps. It is also possible to turn off DirectX support, but that requires fumbling in the Windows Registry, so first please check your drivers.

July, PC World magazine, pg. 68 says, "Windows Vista's DirectX 10 technology promises richer applications and more life-like games, but to enjoy them you'll need a DX10-ready graphics card."
Does this mean V11 will run better under Vista, and should I buy a video card that is DX-10 ready?

Oops! Just noticed that xp supports DirectX-just not 10. Still, if this is a video card problem, that would be good to know.

Thanks,

I have noticed a specific slow-down in AC11 970. Open an independent worksheet and use Trace and Compare to reference in a building section. Now try and do anything. On my configuration there is a slow-down associated with every mouse action: click—wait—drag—wait, etc. Totally unusable. It appears the reference is trying to update with each action. Autorebuild or manual section doesn't matter. Weird since references normally must be manually rebuilt.

Anyone else getting this?

Bummer since this is the target usage, i.e. draft a section or elevation with the model as an underlay. Superior (in principle) to the old standbys of dragging a copy or unlinking.

I've got similar problems during Beta - slowdown when using Trace, selecting and moving objects and most worse - copying to clipboard (best time was about 2 minutes! 🙂 )
All bugs were fixed in succeeding beta versions.
Simple solution was merging old project to new one (from template).
Try this.

There are many slow down issues.

The program does seem quite a bit slower to me.

When I have something surrounded with the marque it is even slower.

?? I still have not installed 11 from the discs being sent out, I downloaded my 970 from the beta site and was able to activate my key from the upgrade site a few days ago.

I am not hopeful that the program coming on the disc will be any different than what I already have. I hope it will be.

I was experiencing some serious slowdowns when my hard drive was nearly full, but since I cleared some 40 gigs it is quite snappy now. AC11 seems to launch much quicker for me than 10 has been.

V11 started off Ok but as soon as I added a curved profile wall it all fell apart. Very slow at moving around the 2D window and between stories. I didn't persevere too long, and deleting the offending wall it all went back to the correct speed.
I do hope this is not another half baked tool.

and when i draw sth in 2D its going very slowly
as if you re watching a video from a cd that the driver cannot read well and its going frame by frame

I'm not personally having any problems with AC11, but one of our framers has struck the same issues you describe - achingly slow performance in 2D. 3D seems to be fine.

They are driving 2 displays so I suggested trying with one only. This seemed to make a difference, but still far slower than AC10. They are going back to AC10 unless I can find a solution soon.

I also found AC11 to be insanely slow in 2D when I first started it up. Then i noticed the little FPS counter in the top right corner, which is only supposed to come up when in 3D apps(games usually). This, as Greg mentioned, is because the 2D windows are now drawn using DirectX, instead of in software as before. This means that if you have a sucky graphics card, the 2D view will be slow. For me the problem was that i had turned on Anti-aliasing in my graphics card driver, and so this was being applied to the 2D window. I turned that off, and now my 2D windows are crazy-fast. I would even venture to say that they are faster than before.

From my experience with version 11 I've found that the speed of redraw within the 2D window is directly related to the Anti Aliasing setting for Direct3D.

This is found under the advanced settings of your display Adapter. There are two 3D settings, one for OpenGL the other is for Direct3D.

When I set the Direct3D AA at "Application Preference" the 2D performance is good but when I set it to 4x or 6x then the 2D is really really slow. So make sure AA is turned off.

ActiveX is a Windows-only technology - the problems reported to me are happening on a Mac. It's not happening on my MBP, so it must be connected to specific configurations.
