[Bug Report] (1.16.4) Massive FPS drops and too high RAM usage.

berkkrkc09 commented 3 years ago

Description of Issue

FPS drops start right after any world loads and RAM usage doesn't even go under 4.2GB(if i remember correctly) in any world. If i give more ram to the game RAM usage just goes up and up and up and up... Thested with a used and a new generated world, tested with and without "Terra Forged" mod and nothing diffrent.(I did this because it was the last new mod i added) F3 screenshot was taken when "Terra Forged" was loaded. I am saying that the ram usage is too much because i played with about 215 mods with the same machine and same amount of ram given to the game but unfortunately i don't have that mod list so i can't narrow the mods.

Steps to Reproduce

Just load a world
Oh, my frames!..

OptiFine Version

OptiFine HD U G5 (1.16.4)

Installation Method

Dropped the JAR file into mods folder.

Forge Version

forge-35.1.13

Other Installed Mods

https://pastebin.com/2WKWkW7z Sorry for the unnecessary info, I had to use a cmd command to get the list. There are more than 250 mods. 😮😐

Prior Testing

If you've installed using Forge:

Does this happen without other mods installed?
- Only OptiFine and Forge --> no
Does this happen without any mods at all?
- Only Forge by itself. --> no
Does this happen in OptiFine standalone? --> no
Does this happen in Vanilla without OptiFine? --> no
Have you tried using a binary search to find which mods cause this issue? --> no (There is more than 250 mods. Sorry!)
- To find conflicting mods, split your mods into 2 groups (not including OptiFine/OptiFabric, obviously). Remove one group, and test in-game. Keep the group that has the problem, and repeat until no more mods can be removed without the issue disappearing.
- Does the issue still happen with only the remaining mods installed? --> ?
  - Forge and remaining mods, without OptiFine --> I don't know because i literrally don't have the hardware to play with this amount of mods without OptiFine. :(

Additional Information

I didn't use any shaderpack or resourcepack. Playig singleplayer.

I am using CurseForge client, if you need i can export the profile for you so you don't have to find all of the specific versions of the mods by hand and you can just import it.

Yesterday i tried to use "Eclipse memory Analyzer" for the possibility of a memory leak. The Program found 2 possible causes but i am not familliar with java so i didn't understand anything.

Looks like a conflict with one of the installed mods. To find the problematic mod

Test with half of the mods and OptiFine
Keep the mods that have the problem
Repeat from 1 until only one mod and OptiFine are left

I also got memory leak issues in 1.16.4, not happening in 1.16.3.

I split mods to about half(excluding coremods and libmods). Both halves are playable and has low RAM usage(around 2/3GB). I didn't expect this outcome. 😶 So what do we do now? @sp614x

yeah, it didn't happen to me on 1.16.3 either.
