Is it up to my graphics card that the imported image is blurry?
I cannot trace through the raster image in Sketchup, but nice and crisp in Layout. Is it up to graphics card? Anything to be done?
OpenGL preferences are already at maximum.
SketchUp does have resolution limits. Your graphics card could have an impact as well. Can you share the original raster image so we can see what you are starting from?
What version of SketchUp are you using? Your profile indicates SketchUp Free (web) but that’s not what your screen shot shows. And if you were using SketchUp Free you wouldn’t have access to LayOut.
This is what I get when I import your image into SketchUp Pro on my machine with Max Texture Size enabled. Click on the picture to see it at full size.
