I've recently had an issue on my laptop that has an integrated video card and a dedicated graphics card. The computer was defaulting to the integrated video card for the Star Citizen program instead of the dedicated graphics card. Therefore, the video was barely functioning within the game. I had to manually change the default video card to the dedicated card instead of the integrated card. Below are some screenshots of what to do to change it.
Right Click on the Desktop and Click on "NVIDIA Control Panel"
This screen will appear. Click on the "Manage 3D settings" link on the left. Then, click on the "Program Settings" tab in the screen.
This screen will appear. Click on the "Add" button under the "1. Select a program to customize:" area.
A new screen will appear that is similar to this. Scroll through the list and find the "StarCitizen" program (not the "CIGPatcher" program) and click on the "Add Selected Program" button on the bottom.
The screen will go back to the "Manage 3D Settings" screen. Here, under the section called "Select the preferred graphics processor for this program:", click the drop down menu and select the "High-performance NVIDIA processor".
Finally, click "Apply" button at the bottom of the screen. This should change the processor from the integrated processor to the NVIDIA processor.
