Blender 64 - Performance error, settings perhaps?

Support Basics & Interface
#1

Hey all.

I decided to try out the 64-bit version of Blender, yes I have an OS and a CPU that are 64-bit.

The problem is this: There was a project I worked on awhile back that, in 32-bit blender had started causing me performance problems so I dropped the project in hopes that perhaps later I could return to it.

I loaded up that project, and even so the performance problem is still there even on the 64-bit (which I believe is supposed to be able to access more memory, I have eight gigs of ram but I don’t think Blender is even coming close to tapping that)

Do I have a setting not set or what?

#2

Are you referring to real-time performance, in the 3D view? If so, I doubt that a 32-to-64 bit upgrade will help much, if at all. That will allow you to access more memory, and load/render larger scenes … but as for working with all that data, displaying and updating it in the 3D view as you make changes, that’s dependent on your graphics card.

#3

I have a GeForce GTX 260, 896 Ram. So I dunno what is causing this issue, it shouldn’t be considering how advanced that card is.

#4

Yeah, with that card you shouldn’t have any serious issues. What exactly are the problems you’re seeing? What are the specs of your system, and the file you’re working on?

#5

The file I’m working on is for a space-based carrier, it’s got quite a few turrets on it (which I know contributes to the performance) which all I did was make one turret and then copied it several times across the board.

After awhile, as I tack on more details to the ship, Blender starts to get choppy. Meaning it no longer becomes a smooth camera movement and instead the screen skips along - the more ‘details’ that are added, the worse it becomes. For example; if I enable the layer that has all the turrets (there are at least forty of these turrets, twenty on top and on the bottom, give or take) Blender’s performance takes a sudden step dive where it’ll take several seconds for me to even more the camera unless I disable the layer in question.

I run on a Intel Core 2 Quad Q9300 with 8 GB of ram on a Vista 64-bit OS (Ultimate)

#6

My sig has the specs of my machine, and it’s not very different from yours. I just did a quick test on a scene of mine: all layers visible with over 1 million faces, GLSL shading enabled with 16 lamps, two 3D views filling the screen … then I duplicated everything. The duplication caused a momentary pause, but after that view navigation was still pretty responsive.

I have noticed while actually working on this project that Blender does occasionally ‘lock up’ for about 10 seconds, but I think it may be a bug/stability issue with the 64-bit build … even this official “64bit release of Blender for Windows is still in a development stage”, as stated on the download page.

How many faces are being displayed in your scene when the lag becomes evident?

#7

Well, the performance issue is also in the 32-bit version, though I did notice that the issue was more noticable in the 64-bit when I brought up the file.

With just the base layer (which has the ship) and the turret layer active:

Faces: 1,651,157
Verts(I’m assuming VE means verts): 1,618,062

I also have not edited any of blenders default settings; as I don’t know if doing so would help.
