I am new in this forum.
Started some weeks ago with SKU.
I used my own house and garden as exersice. Nice.
But suddenly I started up the file and selection was extreme slow.
I found a solution which works since every day
I created a small file with some basic groups like cube and cylinder. I open SKU now always with that file and selection works very fast.
Next I open my big working file (40 mb) even with lots of textures etc. All works at high performance.
Intel HD4000 integrated
2x4 GB Kingston HyperX Fury
SSD 256 Drive.
