FPS capped at 144 Hz in Sodium 1.21.11 but not in 1.21.1 (240 Hz monitor)

[TimToiletWarrior]

Bug Description

When using Sodium 1.21.11, my FPS is consistently capped at exactly 144 FPS, even though my monitor runs at 240 Hz.

This issue does not occur in Sodium 1.21.1, where I get the expected ~240 FPS under the same conditions.

Reproduction Steps

1. Install Minecraft with Sodium 1.21.11

2. Launch the game with only Sodium installed (no other mods)

3. Observe that FPS is capped at exactly 144

4. Downgrade to Sodium 1.21.1

5. Launch the game again under the same conditions

6. FPS returns to ~240

Expected Behavior
FPS should not be capped at 144 and should match the monitor refresh rate (~240 FPS).

Actual Behavior
FPS is consistently capped at exactly 144 FPS in Sodium 1.21.11.
