I Like Sodium, It Is Very Good.
But A Minecraft Block Makes Still Lagging

That Is Signs. In Some Of Map Metropolis Places Still Lag Because There Have Lot Of Signs
Even Chinese Words Is Most Lag If Type On Signs.
I Suggest To Make Sodium Can No Rendering Signs Behind Blocks But Still Rendering Signs Behind Transparent Blocks Like Glass And Iron Bars

This Feature Can Makes No Lagging In All Maps.
I Suggest This Map For Test And Debug. https://www.planetminecraft.com/project/my-first-minecraft-world-republic-of-flashteens/
