Extreme Frame drop from 750 to 45fps

I’m currently playing on Minecraft 1.21.8 using the Modrinth Launcher with Iris + Sodium. I’m experiencing a big performance drop compared to last year, and I’d really appreciate some help identifying what’s causing it. A year ago, I could run BSL shaders at around 200 FPS consistently. Now, I only get 45–60 FPS, even though VSync is disabled. Render distance: 12 chunks → ~45 FPS with shaders Render distance: 2 chunks → ~60 FPS Resolution: 1440p (switching to 1080p makes no difference) System specs: CPU: AMD Ryzen 5 7600 GPU: AMD Radeon RX 6800 (16 GB) RAM: 32 GB DDR5 @ 6000 MHz (10 GB allocated to Minecraft) What I’ve already tried: * DDU → Clean driver reinstall * DDU → Reinstalled older AMD drivers * Tried other launchers * Set javaw.exe to High Performance in both Windows and AMD Adrenalin I’d love to get back to the performance I had before and be able to enjoy shaders again. Any suggestions or troubleshooting steps would be greatly appreciated!
