There is a new version of DX10 Scenery Fixer, Version 4.0.
The biggest change is that there is no longer a legacy slider….
The fixer can now distinguish aircraft and scenery and use different rules for the two which solves a lot of issues. I believe that all legacy aircraft (built with FS8 SDK) will display exactly the same as in DX9 – with the single exception of any 8 bit textures which require separate conversion to DXT1. You should find that legacy scenery display better as well. The night lighting should be identical to DX9 and much brighter than before. All the Aerosoft, Taxi2Gate, UK2000 airport sceneries that I have examined exactly the same as in DX9 ( with the exceptions of a few AES lite buses and trains).
The release also has improved shadows and better and more reliable effect fixes and numerous fog fixes for Orbx airports.
