Real Weather 2 Total HD

Promise is debt!!! 
This is an improvement of weather mod, this version brings high-resolution textures, but also allows a small improvement for those who have DirectX 9 video card. 
Raindrops have a lower pixelated effect in the mod with smaller droplets. 
he version with DirectX 11 can also be used with DirectX 9, but as it increases the size of raindrops, more pixelated effect will have on DirectX 9 video cards, so your own version is the best option, there were other improvements too, like the spray of water from the cars. 
The mod offers a better experience on DirectX 11, but has its improvements in DirectX 9 ( the raindrops ).
But some pixelated in the spray will have always , even in HD, the same is not true in DirectX 11,  due to the spiral effect of water spray in an attempt to become more realistic. 
Enjoy!!
