My sketchup using only 15% of cpu but why it's still lagging

SketchUp
1

As i type on the topic i’m working on 0.2GB spk. file right now and it using 4-15% while moving or rotating model. I just bought new PC ( couple of months ago) with spec : Intel i7 | RTX 4060 | ram32 GB that i think its already high spce enough to do with everything. I doesn’t have problem much with it just annoying and it’s better than my old laptop.

Here my question do i have to do something with my sketchup and/or PC or if it’s because of some problem? Thank you

Ps. I’m so bad about PC thingy doesn’t really know about technical term and English isn’t my first language please bare with me.

SketchUp like other 3D modeling applications is a single threaded thing. It doesn’t matter how many cores your CPU has, SketchUp will only use one.

Most often the thing you need to do is improve the model. If you share the SketchUp file with us we can give you some ideas about how to do that.

A 200 Mb file is quite large. I’ll guess it can be streamlined quite a lot.
