Slow Blender

[Tinuviel]

I really hope someone can help me, I'm starting to get very frustrated:-) When ever I model something and get several objects on the same sceene, my Blender slows down. For instance, if I try to scale, I have to wait seconds before scaling is activated, and then more before Blender responds to my mouse moving. At first I thought the reason was my laptop, so I formated it. Then I reistalled Blender. Same thing happened after a while. Then I saw other people having the same problem with ATI grafics card. So I have now tried several of the latest drives, but still the same problem. I know for some people it have helped to put some sort of a .dll file into Blender, but I'm not sure how to do that. For others it have helped to use other drivers. If anyone have a solution for this I would be very happy. At this point I am stuck modeling very low poly meshes, but I would really like to do a bit more complex stuff to. Well, with my skill it's more proper to say Try to model something more complex. Lol

PS: I'm not good at this PC thing, so I hope anyone with a solution can feed it to with a teaspoon.
I have ATI mobility radeon 9700
Windows XP

Do you know how many steps you're allowed to undo? If the limit's large, blender slows down after a while, and that might be causing the symptoms you're describing. (To change this setting, set a window to User Preferences, click on Edit Methods, and look for "Undo" near the left.)

thanks for replying. I have tested now. I had it on 32, changed it to 9. Still the same result.

Let me ask you a different questions:

CPU: type and speed?

RAM: How much do you have?

[Tinuviel]

CPU is the same as my prossessor right?
If so I have Intel Pentium 1.8Ghz and 512 RAM

[andylegate]

That's not so bad. right now I'm running on Celeron 3.06 Ghz and 512 mb.

Blender stutters for me everyonce in a while when I'm trying to look at large section of my Ages. Or if I swing around to look at something that is very large, with a LOT of faces on the mesh, and it's textured.

[Tinuviel]

I just checked the use of my CPU. I selected one object witch have about 10 faces. Went to Edit and hit s to scale, that made Blender use 99 % of my CPU. Some of the other objects have more faces off course. I just do not know why it is doing this suddently again. It have worked perfectly with bigger projects earlyer.

[andylegate]

I'm not sure what causes it, but I know what you're talking about.

I have a large concrete dam in Camp Bravo. Everytime it comes into my scene in blender, I get stutters and pauses. Yet at the same time, have huge cliffs with literally a thousand more verticies than that dam, and they don't cause it at all. I just learned to live with it.

Of course my computer will be getting a huge upgrade come this Wednesday, so maybe I'll see a difference myself.

It would be of more help for you to tell us what video chip-set your using?
and does your laptop have shared memory?

Many laptops have shared memory, which gets eaten very quickly forcing the OS and programs to use the pagefile ie the hard drive, and because the hardrive is much much slower to read and write than memory, it compounds on you when you use such high graphical programs and games.

I believe this is a case of "get your money's worth".

When I get my laptop, I already know to look for one with separate dedicated memory

[Tinuviel]

Ehh Sorry, not sure if I can find my Video chipset.... Could you please tell me where to find it? I looked under my system and then to something I do not know the english word for. It says nothing about Video. I can only find the Ati mobility radeon 9700. But that is only for grafics? My Haddisk is split in two: one C and one D. I guess that means I have a shared memory.
I went to blenderartist.org and I see several ohers have the same problem with their ATI-card. But I have tried most of those solutions and I still have the problem:-(
If you could help I would be so happy.!!
