.Net Framework version requirements

Hello. I’m new to Pro - I’m testing the program on a 30 day trial. The program seems to be very slow (especially using Layout) compared to what I see on the training videos, so I’m wondering if I have the right system. I’m using Windows 10, 64 bit, NVIDIA GeForce RTX 2060 graphics card and .net framework 4.8. Sketchup says I need .net framework 4.5.2. - it doesn’t say “or later”. Is this a problem? I like the promises of Pro, but it’s seems very clunky.
Thanks for your help.

There are many things that can affect the program.
Proper installation, did you right click on the downloaded file and choose run as administrator.
The latest video driver package.
Overall health of the Windows installation and the drivers required to operate correctly.
Exactly what is the unit you have? Power supply, motherboard, memory type and speed,processor size, storage system, video memory…
