I used to have a bad system, and I wanted to play all the custom BC ships I could find.
When I could not, I began searching for a method to do it. I will now share this with all of you.
BC Ship Images are .TGA files. You can do a simple resize with an Image Editor called "XNView".
Instructions: 1-Download XNView: XnView Software - Free graphic and photo viewer, converter, organizer 2-Install it. 3-After Installation, find a ship Image to edit, and double click it. It should ask you to select a program to run with it. Find XNView in the list and select it. 4-After the Image is displayed, press Shift+S (Shift key with S AT THE SAME TIME) to open the resize interface. 5-In this interface, simply use the drop down menu to select 50%. 6-Close the program, pressing yes on all prompts. 7-Enjoy the better frame rates!
NOTE: If you still have issues, then just 50% them again.
DISCLAIMER: I take no responsibility for anything that happens to your BC ships. I am posting this because I was once in other player's shoes with a bad system.
this stuff would be better served on BCC "Bridge Commander Central"
