Entity Rendering Performance Significantly Worse Than Vanilla On 1.21.5
Bug Description
Entity rendering performance is a crucial aspect of any Minecraft mod, and Sodium, a popular Fabric mod, has been known to offer improved performance in various scenarios. However, a recent issue has been reported where Sodium's entity rendering performance is significantly worse than vanilla on Minecraft version 1.21.5. This problem was first noticed on servers that utilize a large number of display entities in their world, which is a common practice in many Minecraft servers.
The Impact of High Entity Counts
High entity counts can be a significant challenge for any Minecraft mod, and Sodium is no exception. The issue at hand is not just a minor performance degradation but a substantial drop in performance that can be felt even in relatively small-scale servers. In a world with approximately 1000 Zombies, vanilla performance is about double what is achieved with Sodium. This is a significant difference, especially considering that many servers rely heavily on display entities to create immersive and engaging gameplay experiences.
Performance Comparison
To better understand the issue, it's essential to compare the performance of Sodium and vanilla Minecraft in a controlled environment. The following images demonstrate the performance difference between Sodium and vanilla Minecraft in a world with a high entity count.
Sodium Performance
Vanilla Performance
As shown in the images, vanilla Minecraft performs significantly better than Sodium in a world with a high entity count. This performance difference can be attributed to various factors, including the mod's rendering engine and optimization techniques.
Tested Versions
The issue was tested using the following versions:
- Sodium: 0.6.13+mc1.21.5
- Fabric API: 0.123.0+1.21.5
Reproduction Steps
To reproduce the issue, follow these steps:
- Install the latest version of Sodium on Minecraft version 1.21.5.
- Summon a few hundred Zombies in a world with a high entity count.
- Compare the performance of Sodium with vanilla Minecraft.
