Through The Inferno [DCS World]

Dynamic and Engaging Air Combat Operations for DCS World

Remove Useless Ground Clutter Objects

Alternatively you can edit the file yourself here:
Setting clutter in-game to 0, doesn’t completely remove them. Doing this will gain some FPS.

Go here:
C:\Users\[YOUR USERNAME]\Saved Games\DCS.openbeta\Config\options.lua

Change these settings to -150000

[“clutterMaxDistance”] = -150000,
