Since KT works with cpu, the graphic card doesn't affect the render, only viewport issues could be. It's a very strange behaviour what you described. Can you post some screenshot and a sample scene, here or at KT forum?
The follow images where created with just the selected only object imported from sketchup, no lights added. All renders were done using the preset "photonmap - medium + AA 0.3".
This first image all settings were default except for changing the sky to background color using red 7, green 9, blue 26. In other words, nearly black. Except for the sun there are no lights in the following renders
This image was created by just changing the sky setting from the image above from background color to sky color.
This image was created using the settings from the above image but reducing the sun radiance color setting to .4.
This image was created with the same settings except the sun was disabled.
I have attached the kerky file saved from the above images.
