[🐛]: New 0.12.x shader performance worse then 0.11.x versions

Confirmation

• I checked that there is no error among the open/closed issues before sending.
• I'm using the latest shader version

Minecraft Version

1.20.x

Graphics Mod

Oculus

Graphics Card (GPU)

NVIDIA

Computer OS

Windows 10

Expected Behavior

Shaders were said to be rewritten and have better performance then before.

Actual Behavior

Performance seems worse then 0.11.x versions (more specifically 0.11.16)

Steps to Reproduce

Clean install on prism launcher, add newest Distant Horizons, play on new world

Additional Information

Specs:
Ryzen 5 5600X
RTX 3070 8GB

Shader settings were imported from last major version, distant horizons are on 100 render radius and medium quality preset. The shaders have new Supplemental and Euphoria pathces settings have not been touched yet.

Forests and especially forests when raining impact performance a lot more then they used to, by roughly 10-15 fps drops when looking at forest. Even in general it seems to have worse performance then before and that could be due to worldgen being changed but even then being in a normal forest when raining and having a torch in my hand sends my gpu in overheat mode which has never happened on older versions. I do have distant horizons enabled and maybe the newer version of dh is worse then older dh version (had 2.3.4-b updated to 2.4.5-b) but even then I lowered the render to 100 from my usual 180.

Old settings:

Current settings:

// might be NO_RAIN_ABOVE_CLOUDS and RAIN_STYLE (2, heavier rain), will need to investigate

I played a lot more past couple of days and I have to add that most foliage lags a lot more with latest shaders, beneath is especially hard on the frames (like 15-20 avg fps), any tree or bush just ads up to uncomfortable small frame stutters. It is hard to pinpoint exactly what about the foliage lags, is it the culling not working, light messing with it or something entirely different. I will do more testing with and without DH.

we don't have any leaf cullers in the pack because they don't work with TFC leaves, so yes they do impact the frames more than most modpacks. TFG shader 3.x has a bigger coverage of waving foliage than TFG shader 2.x so maybe waving foliage is causing you some grief. But to be completely honest, the biggest difference is complementary. TFG 2.x uses comp 5.0.1 whilst TFG 3.x uses 5.7.1 + euphoria patches. I don't think we'll be able to help performance unless we do drastic changes to comp itself, which is far off if we even do it.
Do some testing with a fresh instance, play with DH settings or vanilla settings. those are things that can help

TLDR: I don't think we'll be able to address your issues any time soon

I see, well it sucks a bit that it isnt a fix that can be done easily with the shaders themselves, I will try and play with settings a lot more and see how it turns out. Anyway thanks for the help
