Extreme fps lag and chunks not rendering properly

[Snivine]

When playing on singleplayer the chunks don't render properly and there's extreme fps lag My hardware if you need it: CPU: Intel Celeron N3060 GPU: Intel HD Graphics 400 RAM: 4GB DDR3L 1600mhz

Hi, thanks for the report :) Which version of the mod is this with?

[Snivine]

it's 0.1.2

[Gegy]

Okay- interesting, will have to investigate further.

[Snivine]

if you wonder I'm running the mod with lithium and sodium, I don't know if that could have something to do

[Snivine]

You have old, low-end hardware and are trying to run high end graphics, possibly fabulous shaders. What you're trying to run requires high-end hardware. Of course you're getting lag and chunks not rendering. I don't understand how no-one can understand this. No wonder some ppl are laughing at this bug report on discord. This feels like a joke post from reddit. You either need to run fast graphics without fancy clouds on render distance 8 or accept that this will constantly happen. Even I don't get 60fps 100% of the time on 1-2 year old mid-range hardware. What makes you think you can?

You're assuming my graphics settings, not only that you're spreading bullshit because I'm pretty sure a 2016 CPU still not old, this PC can run the game with Lithium+Phosphor+Sodium at stable 40 FPS, I have EVERYTHING on fast, and this lag doesn't happens normally, please ask first and then comment, don't just assume. ![Uploading IMG_20201023_123054.jpg…]()

I have a laptop with such specs(except the ram is different),sometimes chunks don't load (or something because pushing entities through them makes them stuck) I am not sure if it happens in the latest release, at some point, I will test and report back. as for the fps lag,I am not sure what is causing it for you (it may be tic-tacs and it may not be)-I have to do more testing to see if it happens to me- have you tried playing the game with only tic-tacs, sodium and lithuim if the lag still happens then we maybe can say it is from tic-tacs, after that, you can try adding phosphor because it may help you.

I did some testing, not very scientific but still, I got some results, I'll lay them out: I have gone through phases of testing:(All mods are up to date from curseforge except for tic-tacs which was from GitHub, and the fabric mod loader is up to date) I was using:

Operating System: Manjaro Linux
Kernel Version: 5.9.1-1-MANJARO
OS Type: 64-bit
Processors: 2 × Intel® Celeron® CPU N3060 @ 1.60GHz
Memory: 1,9 GiB of RAM(2GB of ram)
Graphics Processor: Mesa DRI Intel® HD Graphics 400

used the bundled jre. and these jvm arguments: -Xmx1G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M PHASE1:LITHIUM + SODIUM + TIC-TACS + FABRIC API Didn't test with this configuration much but here is what I noticed: I flew around in creative after a bit of flying I noticed a bit of terrain not rendering(blocks seem to be there and I can break them) switching the rendering backend to opengl 3.0 rendered a bit of terrain and then to 2.0 the same bit got rerendered and switching back to 4.3 the same bit got rendered. quitting from the world and then opening it again rendered the chunks properly(Not sure about f3+a) in the image, it doesn't show well but blocks were pointable. PHASE2:LITHIUM + TIC-TACS + FABRIC API(sodium removed) I flew around, didn't notice any terrain that was loaded yet not rendered but I noticed some chunks that weren't loaded in the first place: Not sure if I would encounter chunks that are loaded but not rendered if I would have played for longer. PHASE3: TIC-TACS + FABRIC API(lithium removed) I flew around for a bit, and found some chunks that aren't loaded, quitting and entering the world fixed them. I realised "chunks that aren't loaded" may not be the correct term because I can stand in them, there seems to be terrain but it behaved like ghost blocks because entities bounce up and down when they stand on them(These are observations from the chunks I found in phase 3, but I think they apply to phase 2-I could be wrong-) to conclude there seems to be an issue but I can't really say for sure because the tests where not that scientific and the results may be completely inaccurate and I may have forgot something or reported something wrongly, so take them with a pinch of salt.

Using a multi-threaded chunk loading mod on a mobile CPU with only 2 cores is at least a 5Head move, Big Brain Plays

Isn't multithreading optional?

"Tic-TACS additionally enables optional multithreading of chunk loading which can bring significant improvement in generation speed, as well as allowing for much higher chunk view distances."

on Windows 10 this issue doesn't happens, tho the FPS lag still there but that's with phosphor and lithium only

nope it still happens, bear in mind that I disabled multithreading

This is much larger than just a rendering bug. I just encountered this on my server. Multiple people see the missing chunks and broken entities around the chunk. While the chunk loading was broken we were able to place blocks of sand in the air and place blocks which were invisible to other people. After a while the server reported that we went into unloaded chunks and would prevent us from joining the server. I then proceeded to try and shutdown the server but this bug caused the server to no longer respond to commands. I eventually had to try kill the process with it's pid and the server will not shutdown. I ended up having to restart my entire server which successfully shutdown the Minecraft server.

This is a vanilla issue, but Tic-TACS makes it easier to occur, I think that Tic-TACS uses more resource than vanilla Minecraft, making it easier to overhead, so I don't know what could be done in this case, maybe find out why it uses more resources?

[EcoBuilder13]

@Snivyer1910 Do you know if this has been reported on the Mojang bug tracker?

[Snivine]

I don't know but sapnap experienced this same issue in 100% vanilla

[EcoBuilder13]

Do you know what version of the game they used? I also found MC-146778 and MC-138114 but it might still be broken.

[Snivine]

they where using 1.16, I don't know the patch number tho, but I'll guess 1.16.1 bc it was a speedrun

I have found that unloading all of the broken chunks then reloading them fixes the errors, but if any player still has them loaded in on server side any player which comes near the chunks will see the error too. It might be possible to unload then reload all the chunks around a player when the game warns of the player entering unloaded chunks. I have noticed this occasionally happens when players near or enter the broken chunks.

[RangoMcRoony]

Same issue occuring for me too. Chunks just refuse to load, F3+A doesn't do much. Restarting the server or world seems to be the only way to fix this. U wasn't sure if this was an issue with Tic-TACS or with starlight but since other people are experiencing this it seems to be a Tic-TACS issue

[EcoBuilder13]

@RangoMcRoony You can also "fix" it on dedicated servers if all the players disconnect and reconnect that are near the broken chunks. This seems to be a problem with the server not sending the chunks to the client correctly. Which is still possible in single player since the game just runs an internal server you connect to.

I use windows, and it it the other way around for me; chunks don't load but the FPS is fine.
