Just as a note for some reason Mojang closed the bug report linked earlier in favour of one made later.

Really sorry about necroing this, but I'm having exactly the same problem with Bedrock and PureBDCraft 256x on our Realm.
I'm running a RTX 3090 and, sometimes, the fps is just fine. But most times it just sinks to around 9 fps and the gpu and cpu use isn't even at 30%, usually not even 20%.
I'm now at v1.16.220 and really don't know what else to try. Already did a full video driver reinstall with DDU and full Minecraft reinstall and nothing seems to work.
It's worth mentioning that resource packs and realms right now are really messed up, since we can't even see which resource packs are active and can't delete or change it. It's just that months ago when I last played the Realm was just fine and we changed nothing since then.
A friend of mine with a 3080 and a 5800X has the same problem.
Please halp!
Thanks for any input.

Thanks, HanFox! And sorry about the wrong place.
I see now that's not as uncommon as I thought. I hope Mojang or Sphax could fix this bug soon.

I would like to expand on this post due to experiencing similar issues. I recently purchased Bedrock version of Minecraft for my new PC. I was previously playing on Xbox Series X with zero issue.

I use the PureBDCraft w/ PureBDCraft HD UI on Minecraft Realms.

I have a storage room setup with item frames to label the boxes with an enchanting area next to it. When looking in that direction of my base framerate drops so bad I can barely move. The only way I can get into my base is by looking at the floor. Also seeing frame rate drops where lots of items are on the ground such as if kelp has been broken and floating in the water. I've had several instances after being in the nether for an extended period of time performance drops to the point where the game is unplayable.

  • If I remove the texture pack zero performance issues.
  • I have deleted and reinstalled the texture pack to Realm and PC several times
  • Updated drivers
  • Taken off realm and ran locally, still performance issues
  • Only happens when playing on PC

I also have the same issue. When going near my storage room with item frames the framerate drops to 2 fps. After removing the items from the item frames the framerate rose back to playable levels (50-68fps). It seems to be the items in the item frames that causes lowered framerates.

It's not item frames it's entities. Simply the number of entities being rendered will drop frames heavily. Even at lower resolution settings. BDCraft historically has blamed Mojang saying it's a problem with all texture packs, but I've tested every high res pack available and BDCraft is the worst performance wise by far. Unfortunately it's also the best looking and I can't really play on any other texture pack since I've gotten so used to it. Even the other 128x packs. Don't think there's another 256x.

The only solution is lowering the res to 128 or 64x which helps but will still get overloaded with too many entities, and limiting the amount of entities that are allowed in a loaded area, which basically makes it not worth playing at all. 1 Guardian farm or really anything complex or worthwhile and it's back to default textures or single digit frames. i7700k/2080Ti/32GB 3200 RAM

I wish it had an option to not apply bdcraft textures to floating item entities as they aren't really neccessary and seem to be the majority of the cause of entity frame drops. Other entities will do it too, but obviously it's easier to mass produce items in farms which is where alot of the "lag" comes from when playing with texture packs like this. Item frames and the like are easy to avoid. Building worthwhile farms that produce tons of items is not.

Having the exact same issue as soon as enough Entitys drop FPS goes into single digits is this going to be fixed ?

FIXED!!!!
At least for the Windows 10 edition that I am playing (From the Windows Store)*** The problem is that the game executable that shows up in Nvidia Control Panel is NOT the executable that the game runs when you launch it, so custom settings are NEVER applied to your game.

The first step is finding the actual .exe the game uses to run off of on your computer
1. Start the game, and then open task manager
2. Find the currently running minecraft exe, right click and select open containing folder
3. find the minecraft executable inside this folder (should be Minecraft.Windows.exe) and copy its file path location
4. Open nvidia control panel and click Add under program settings tab
5. Click browse, and then paste the file path you copied into the top input field
6. Select the Minecraft.Windows.exe that shows up in this folder

Now you can get on with editing the settings for the ACTUAL executable that cause the FPS drop. I noticed that minecraft was NOT using my 3080 to actually do 3d rendering for the game, which tells me that the game is bottlenecking the CPU for some stupid reason. In order to offload to the GPU, I changed the following settings;
1. Cuda GPUs - All
2. ***Low Latency Mode - Ultra (This prevents frame queing on the CPU, which allows the GPU to process them faster)
3. OpenGL Rendering GPU - Select your actual graphics card
4. Power Management Mode - Prefer max performance
5. Preferred Refresh rate - highest available
6. Virtual Reality pre-rendered frames - 1

I went from 5-15 fps inside my house, to over 240 fps instantly. Zero lag spikes, and zero fps drops. Cheers, and I hope this works for you.

Someone active on the Mojang Bug Tracker report (linked earlier in this thread) tried the stated settings and it didn't improve their FPS.

Whilst it doesn't mean this won't work for some people it's not a definitive workaround and, thus, still needs Mojang to rectify the issue in their game engine.
