For those that want to play on DX9 render this is the simplest way:



1. backup "config.blk" in War Thunder folder, simply copy-paste it in same folder

2. open "config.blk" in War Thunder folder, using notepad

3. find these these two lines which start with renderer (both near the top) and change them to:

renderer2:t="d3d9ex"
renderer3:t="d3d9ex"

("dx9" might also work, but this looks prettier with no FPS cost for me)

4. save and close the file, continue to run the game as you normally do



If any problems arise you have your backup. Launcher renderer box will be empty so you wont be able to tell which rendered is actually being used but in my case the effect was immediately noticeable in-game by having exact same FPS as my usual dx9ex (25% more than dx11).

This way also prevents potential future problems by having to ready-only the config file, as suggested in link in previous post (http://forum.warthun...cher/?p=4410911), and forgetting to untick read-only when the patching starts. You may have to check if a future patch rewrites those two lines and change them back if needed.
