I took your recommendation and started digging up my system information. While double checking my graphics drivers were up to date, I noticed GeForce Experience had KSP listed as one of their supported games, so I went ahead and hit the optimize button. When I fired the game back up, shadows were working. So that's a victory, even if it's a slightly bewildering one. Below is my system specs, if anybody is interested. I'd like to thank you all for trying to help. Even though the solution seems like a trivial one, I don't think I'd have found it without first trying to trouble-shoot here. ------------------ System Information ------------------ Operating System: Windows 7 Professional 64-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_gdr.140303-2144) Language: English (Regional Setting: English) System Manufacturer: System manufacturer System Model: System Product Name BIOS: BIOS Date: 06/04/12 17:18:09 Ver: 14.04 Processor: Intel® Core i7-3930K CPU @ 3.20GHz (12 CPUs), ~3.2GHz Memory: 16384MB RAM Available OS Memory: 16356MB RAM Page File: 3606MB used, 29102MB available Windows Dir: C:\Windows DirectX Version: DirectX 11 DX Setup Parameters: Not found User DPI Setting: Using System DPI System DPI Setting: 96 DPI (100 percent) DWM DPI Scaling: Disabled DxDiag Version: 6.01.7601.17514 32bit Unicode ------------ DxDiag Notes ------------ Display Tab 1: No problems found.
