Assetto Corsa Stretched Screen

https://www.imghost.net/hK9MFjV8AT7czEt[object Object] Hello, I've been playing Assetto Corsa since a year, and I recently heard of Reshade.
I've installed a lot of car packs and essential tools as Pure and CSP, as shown in videos.
I've seen some videos and it looks incredible, but I never managed to make it work on my game.

Every filter that I tried, made my screen look stretched and in a poor quality, so I was forced to disable it...

I wanted to know if some of you are aware of the problem, and how to resolve it.

Here is some screenshots 

Thank you guys !

Hello, first your screenshots look a bit dark. Can you check which one of your enabled FX does that?

Thanks for your answer and sorry for the delay.
I tried fx one by one to see which of them does this but no one had this effect.

I reset my pure settings and my game is brighter like that.
When I toggle Reshade, all the menus and things written become really blur at the very limit readable.
I don't know which part of my game/plugins does that.
Here are screens with pure resetted and with un/toggle of reshade
