Literally, sodium is now not of any use vanilla is better i don't wanna say anything :
My specs
Intel core i3 10th gen
Intel UHD Graphics
4gb ram
256gb SSD
Now just see these images. All of the settings are set to unlimited fps with vsync toggled off:
Performance with sodium in fabric:

Performance with sodium in quilt:

Performance in vulkan mod in fabric:

Performance in Vanilla:

Performance with Optifine:

You benchmark nothing. Sodium optimizes terrain rendering and some other processes, but there is no single chunk of terrain in your test scene. So, in fact, you measure the GUI rendering performance, which isn't modified by Sodium.

Comment above was pretty clear, you're comparing performance in a scene where nothing is rendered. Compare FPS in a scene with actual terrain. In any case this is not a support forum, if you're having performance issues go to the Discord server for help.

thanks
looking forward for better updates , btw thanks for support
