I checked the current release of Caret5 for Windows, version 5.613. I have only one PC on which to test it, and the graphics are responsive and Direct Rendering is on (with ATI as the OpenGL vendor).
In the caret distribution is a directory named "lib_windows_software_opengl". These are software OpenGL libraries and, if they are used, the graphics will be slow and Direct Rendering will be listed as Off. These libraries should only be used when there is a problem with the computer's OpenGL libraries. If these libraries are being used, the "OpenGL vendor" is listed as Microsoft. When you view Help Menu->About OpenGL, what is listed for the "OpenGL vendor"? It should be ATI or NVIDIA. If the vendor is anything else, you probably are getting the wrong OpenGL libraries. If so, search your computer for the file "OpenGL32.dll". For any found, right click the OpenGL.dll file and select Properties from the menu. Select the Version tab in the dialog and it will list the creator (vendor) of the library.
