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
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.
