RenderDragon is too heavy: Vibrant Visuals causes unplayable lag

I am writing to express my disappointment with how the RenderDragon engine handles graphics in Minecraft Bedrock. Ever since the old shader system was removed, regular players have lost the ability to enjoy aesthetic visual mods safely.While Mojang introduced the "Vibrant Visuals" (Deferred Technical Preview) feature, it is incredibly heavy and causes severe lag on many devices. I can technically turn it on, but the performance is unplayable due to the heavy frame drops. We shouldn't be forced to choose between the vanilla boring graphics or a heavily lagging game. Please optimize RenderDragon or give us back a lighter, optimized way to run custom community shaders without relying on high-end hardware or third-party apps.
