Fabric Loader: 0.6.1.51
Sodium: 0.1.0

Some people said it doesn't work for them, not working for me either, so I felt like pointing it out. I get the same FPS with Sodium on that I get in normal vanilla (60-100 normally). Probably has an easy fix that I'm not aware of.

Here's my specs: It's not shown here but I also have GeForce 820M GPU (not the best, or even decent, I know)

Tech support is better suited to the Discord server.
Performance depends on a variety of factors, so can't be considered a bug unless you're showing that sodium handles a specific thing worse than vanilla.
