ANOTHER EDIT!!: A new version of the Suite, v2.3 has all these fixes incorporated (and a few others too) – you can download that instead from AVSIM
EDIT: If you are still having problems, try using this version
A patch to bring version 2.2 up to 2.21 is up at AVSIM. Here’s the readme:
FsdsxTweak v2.21 patch for version 2.2
Dave Nunez (firstname.lastname@example.org or https://davenunez.wordpress.com)
This is a patch to be applied ONLY over version 2.2 of the FSDSxTweak suite. It fixes a bug associated with bloom parameters. In v2.2, turning bloom to ‘off’ did not actually inhibit the bloom. Please note that after applying this bug, you need to check all your materials created with v2.2 to ensure that they have the bloom parameter you want (use FSDSxTweak_Edit and ensure that the correct setting appears in the bloom parameters part of the materials tab).
Installation: Locate the files fsdsxtweak_edit.exe and fsdsxtweak.exe on your system, and overwrite them with these newer ones. Double click each to ensure you now have version 2.21 installed. By default, these two files are installed into your FSDS folder.
