Kyne's Grass - This is a new grass mod that has high compatibility and decent performance and also looks really nice.
Verdant - A Skyrim Grass Plugin + Snow Grass & OC Update Patch (I prefer this one over Veydosebrom because it has a much higher compatibility) OR.
Skyrim 2017 Textures - 4K Diffuse 2K Normal Map - Briddges.
