deldevin This is... not very actionable. It almost reads like you were expecting this to be some kind of known issue. No details about your setup, which specific shader mod and shader pack you're using that is giving you problems, just "laggs with shaders". You're the first person to report anything like this. The only known issues with shaders (which have already been fixed) were issues with Fullbright and the brightness of ores when using X-Ray while Iris is installed. That's it. No known performance issues. Shaders have been working fine for everyone else, aside from Minecraft being in the middle of an OpenGL to Vulkan transition which is outside of Wurst's control. What do you expect me to do here? I need details.
