Managed to port glsl code to hlsl for FXAA.
Seems to work.

Attaching it for people who need it. It looks simpler than the Fxaa 3.11. I am guessing its the old version. But it performs better.
Tried with and without Luma. Works in both cases.

On DX9 you need to do color space conversion, in order to use it correctly.

I do something like this:

Stage 0
Render Main Scene to texture
- Texture Read convert - SRGB to Linear
- Texture Write convert - None

Stage 0.5 (Optional, if filling alpha with luma)
Render Texture to Texture
- Texture Read convert - None
- Texture Write convert - None

Stage 1
Render Texture to Monitor using FXAA
- Texture Read convert - None
- Texture Write convert - Linear to SRGB (as Monitor requires SRGB format)

Hopefully that clarifies some stuff.

For now this works.

@Dragon. Couldn't get the Fxaa 3.11 to work though. I rechecked all the variables, I am not sure whats the problem. if you find something wrong, please tell me. Attaching the updated old one again. Attaching some part of the code, if someone wants to see.

I have a question
FPS drops as follows (@1080p):
- Normal Render (1500 FPS)
- Render To Texture (1000 FPS)
- Texture To Scene with FXAA (500 FPS)
Is that normal ?
