Changes over r5.9_dev1:
Improved frame rates by around 3% to 10% in most cases thanks to a few small performance improvements:
Improved terrain and shadow rendering performance a bit with technical changes. Most noticeable with higher render distances. Thanks to cortex
Improved regular fog performance. Thanks to plazmal
Improved performance in scenes with lots of transparent particles. Thanks to plazmal
Tweaked sky horizon to look less saturated during noon
Tweaked ambient occlusion for the Voxy mod to improve the look of grass. Thanks to plazmal
Slightly tweaked noon lighting color of Reimagined/Unbound clouds
Slightly tweaked shading of "Vanilla" clouds
Added separate "Noon" and "Sunset" intensity settings for light shafts
The "Improved Glass" IntegratedPBR option is now enabled by default
Lowered the settings of "Very High" and "Ultra" profiles, and added a new "Complementary" tier as the new highest Profile
"Very High" profile almost only enables colored lighting and rain puddles. It's suited for people that want most features without going into enthusiast territory. This would be the new default profile if it was compatible with all devices
"Ultra" profile increases several settings by a tier, and also enables World-Space Reflections. It's suited for enthusiasts that care about small details
The "Complementary" profile nearly maximizes everything but leaves out setting levels that are nearly impossible to notice in gameplay
After these changes, the gap between each profile should be around 15-25% fps. (But there are many exceptional cases)
Fixed "Vanilla" clouds looking extremely dark during thunderstorms
Fixed waterlogged leaves looking incorrect if the "RP Support" option isn't set to IntegratedPBR
Fixed visuals breaking with Voxy in Minecraft 26.2 (only applies if/when Voxy releases for 26.2 with shader support)
