I am new on blender, and I seems to have one really annoying problem. I thought my PC is pretty good but seems as I am not right.

i7-8700 CPU @ 3.20 GHz 32GB RAM NVIDIA GeForce GTX 1060 6GB

and my PC seems to barely handle? I mean in most case with Subdivision surface makes my PC go wild and most of times just close down blender. If I do some animation and try to see how does it look like, its nearly to impossible to play it. My blender goes "Not Resposing" a lot of times, even when moving items, but happens usually when I am further down with the project. Wonder if I there is anyway to boost it up? Or am I doing something wrong?

  • $\begingroup$ What levels is the subdivision surface on your object? How many faces does the object have? $\endgroup$ May 30, 2021 at 16:39
  • $\begingroup$ above if I go 10 if usually goes crazy - hard to say how many faces $\endgroup$

  • $\begingroup$ Really! @user124943 10 Subdivisions is millions of faces! Don't go above 3 or 4 or 6 at the maximum! No wonder your computer crashes. It is supposed to crash under such high loads. Even 4 subdivisions are very high! $\endgroup$ Jun 1, 2021 at 11:23

10 Subdivisions are too high. Thats an extreme amount of subdivisions. 4 subdivisions are also very high, and sometimes 5 or 6 subdivisions makes your pc crash while rendering. Subdivisions should be around 2 or 3 subdivisios unless you want to increase your subdivisions and go upto millions of faces. If only one object has millions of subdivisions/faces, then of course your whole pc should crash when trying to move that onject, not only blender. Why do you need 10 subdivisions anyway? Thats a very very very extreme amount.
