Blender Lag Problems.

Hello Everyone,

I am new to blender and I am having a lagging problem. I followed a tutorial on modelling a train tunnel. I modelled a train track piece and applied a mirror modifier, array modifier, and a curve modifier. The curve modifier was so that it followed a nurbs path that was giving the tunnel its path. On the array modifier it was duplicated about 160 times and since there is a mirror modifier that single track piece would be duplicated 380 times. After that is done I tried to move the train track but it just lags a lot and has massive delay when I try to move it. So I was wondering if my computer doesn’t have enough processing power or is it something else.


Operating System: Windows 7 Home Premium 64-bit
Processor: Intel® Core™ i7-2600K CPU @ 3.40GHz (8 CPUs), ~3.4GHz
Ram: 8GB
Graphics Card: NVIDIA GeForce GTX 580 3GB Memory

Now the thing I found strange was that in the tutorial it was not lagging and I checked the specs for the person who made the tutorial and I found that it is similar to mine.

Thanks in advance.

Hi Bolor,

your system looks very good…sounds like the scene is just too complex to update quickly in preview.

Do you have preview set to Wireframe? Would it help to hide some of the elements until you’re ready to render?

Do you have a link to the tutorial?
