Standard cockpit textures downscaled from 4K to 2K. I've also removed all mipmaps from them, so those textures should retain quality even on low texture quality setting. I did like zero extra-editing because everything seems to be readable already.
Installation (assuming.you're using OpenBeta, for stable place it in the DCS folder instead of DCS.openbeta):
Extract "A-10C-2020-CPT" folder into your "Saved Games\DCS.openbeta\Liveries\" and then select "Aged_reduced" option in A-10C II's special options.
Things to do:
Fix white mirrors
Improve CDU & UFC keyboard readability
Fix some artifacts on gauges.
