If your Logitech mouse is running fine in other programs, but very slowly in SketchUp, there is a setting you can switch to eliminate this problem. The newer Logitech mouse drivers have a special setting for use with games that disables acceleration, but this actually applies to all applications that use OpenGL, which includes SketchUp. To re-enable acceleration: Open the "Properties" dialog box for your Logitech mouse driver. Click the "Motion" tab. Clear the "Disable acceleration in games" check box.
3D applications, such as SketchUp, require abundant system resources. Aside from having a fast CPU and large amounts of RAM, your video card and video card drivers must be 100% OpenGL compliant. What is OpenGL? OpenGL is the industry-standard graphics library used in numerous software applications and games, to draw 3D geometry. Most Microsoft Windows and Apple OS X operating systems come with a software-based OpenGL driver. However, these drivers rely heavily on the CPU to perform the rendering calculations of OpenGL (a task that is not done efficiently by most CPUs).
SketchUp can be a graphics-intensive program. Getting your work done can be difficult if graphics performance is slow or choppy.
