Frame Drop instead of Performance Increase

[TqLxQuanZ]

Hello there! I am the author of DeceasedCraft and recently there are people suggesting me to add this mod,
after some several testing, I compared with 240 zombies on same spot with NoAI on,
With AR:
FPS: 80

Without AR:
FPS 210

May I ask is there some kind of configuration needed to tweak for it to works? For some reason I didn't get frame boost but instead I have frame drop issues worse than vanilla version.

Here's two of the comparison for the photo:
With AR:

Without AR:

Forge Version: Forge 47.4.0
Mod Version: acceleratedrendering-1.0.8-1.20.1-alpha.jar
SparkC: https://spark.lucko.me/KQfK6Lva5v

Is there any log? it seems that there is a log spam.

Also, EMF support is broken, try disabling EMF

Log is being spammed with OpenGL error

[03Jan2026 22:40:21.819] [Render thread/INFO] [com.mojang.blaze3d.platform.GlDebug/]: OpenGL debug message: id=1007, source=API, type=ERROR, severity=HIGH, message='No detailed debug message due to a non-debug context'

Is there a way to keep EMF on but I don't use the AR entity rendering for the entities? EMF is currently used for something else, if there's no support or at least a toggle I guess it can't be helped.

[Argon4W]

There is currently no toggle for EMF, 1.0.9 will remove EMF support.

I have totally no idea about the logspam, could you pack your modpack into mrpack format and upload here so that i can check for that?

[TqLxQuanZ]

hmm what's a mrpack format? I am not sure if curseforge can do something like that,
as for the modpack, it's directly on the curseforge already
Refer to 5.10.14 version.

Ok then can you upload your save here? The one that drops frame rate.

Sure! Here's the world file, once you installed the modpack with Curseforge launcher, you can try add Accelerated Rendering on your end and toggle it on and off to see the FPS differences.
Let me know if you need anything, or if you have a discord/bilibili we can chat easier.
