For the record the reason I didn't reply to Ted80's PM, is I don't trust him (sorry).
It's a long story, but involves the mass deletion of content and features from BoP simply to avoid updating it, including code I had only recently rewritten. When I asked for permission to use the deleted code I wrote, as a separate mod I was abused by the current team and totally ignored by Ted.

Wait are you talking about the removal of the Promised Land dimension? because that happend after I left the bop team.

Wow, delete happy much ?
It's just the APIs for Thaumcraft, MFR, Forestry all you do is import them.
Oh by the way I did ask for permission to use those APIs, unlike some.
Guess what, the Multiworld API is copyrighted, and not open source. You're in a lot of hot water already.

lol

I have no idea what you're talking about, I haven't been working on bop for over a year now.

I've got 2 questions:

1. what bugs do I need to fix?

2. do you guys like the custom blocks a lot? is it worth keeping them? (because it's a lot of work to keep them compatible with all those other mods)

Id like an option for smaller biomes too. The RWG looks really cool, but I keep spawning in savannah/desert areas, and I fly for days and cant find any other biomes. Its just a huge endless dry place.

edit: I finally found a cold forest. Now Im on the look out for a jungle!
Ted, do you plan on adding swamps eventually? I so loved your swamps!

Swamps, jungles, oceans and coasts biomes will be added in the next big update

Please make ExtrabiomesXL compatible! The BOP is very laggy, and buggy... PLEASE!!!

ExtraBiomesXL and Highlands support is coming soon!

I can keep the highlands mod alive if I have permission from fabricator77

Ted, Hi! I am really digging on the FWG mod. I've recently upgraded from BWG, which I was using to run a skyland server. WHen I attempt to to connect to the server running FWG, the client crashes. Here's a link to my client log: http://paste.ee/p/1tLwT I'm not quite sure what I'm doing wrong. Here's my server.properties:

generator-settings=SKYDIM\#0

Can you take a look and see if you have any insight? Thanks!

V1.0.3 should fix it: http://www.mediafire.com/download/15o11e8m3e4qad2/FWG-1.0.3.jar

i downloaded the newest version which is 1.7.10 version 1.2.02 and i just get one world type which is the Realistic Alpha any idea why i have this problem?

What world types did you expect?

RWG + BetterFoliage + CUDA-Shaders v5 Ultra (DEV 16)

Minecraft 1.8 has so many performance problems that I just don't know where to start with.

Maybe the biggest and the ugliest problem is the memory allocation. Currently the game allocates (and throws away immediately) 50 MB/sec when standing still and up to 200 MB/sec when moving. That is just crazy.

What happens when the game allocates 200 MB memory every second and discards them immediately?

1. With a default memory limit of 1GB (1000 MB) and working memory of about 200 MB Java has to make a full garbage collection every 4 seconds otherwise it would run out of memory. When running with 60 fps, one frame takes about 16 ms. In order not to be noticeable, the garbage collection should run in 10-15 ms maximum. In this minimal time it has to decide which of the several hundred thausand newly generated objects are garbage and can be discarded and which are not. This is a huge amount of work and it needs a very powerful CPU in order to finish in 10 ms.

2. Why not give it more memory?
Let's give Minecraft 4 GB of RAM to play with. This would need a PC with at least 8 GB RAM (as the real memory usage is almost double the memory visible in Java). If the VM decides to use all the memory, then it will increase the time between the garbage collections (20 sec instead of 4), but it will also increase the garbage collection time by 4, so every 20 seconds there will be one massive lag spike.

3. Why not use incremental garbage collection?
The latest version of the launcher by default enables incremental garbage collection (-XX:+CMSIncrementalMode) which in theory should replace the one big GC with many shorter incremental GCs. However the problem is that the time at which the smaller GCs happen and their duration are mostly random. Also they are not much shorter (maybe 50%) than a full scale GC. That means that the FPS starts to fluctuate up and down and there are a lot of random lag spikes. The stable FPS with a lag spike from time to time is replaced with unstable FPS and microstutter (or not very micro depending on the CPU). This strategy can only work with a powerful enough CPU so that the random lag spikes become small enough not to be noticeable.

4. How did that work in previous releases?
The previous Minecraft releases were much less memory hungry. The original Notch code (pre 1.3) was allocating about 10-20 MB/sec which was much more easy to control and optimize. The rendering itself needed only 1-2 MB/sec and was designed to minimize memory waste (reusing buffers, etc). The 200 MB/sec is pushing the limits and forcing the garbage collector to do a lot of work which takes time. If it was possible to control how and when the GC works then maybe it would be possible to distribute the GC pauses such that they are not noticeable or less disturbing. However there is no such control in the current Java VM.

5. Why is 1.8 allocating so much memory?
This is the best part - over 90% of the memory allocation is not needed at all. Most of the memory is probably allocated to make the life of the developers easier.
- There are huge amounts of objects which are allocated and discarded milliseconds later.
- All internal methods which used parameters (x, y, z) are now converted to one parameter (BlockPos) which is immutable. So if you need to check another position around the current one you have to allocate a new BlockPos or invent some object cache which will probaby be slower. This alone is a huge memory waste.
- The chunk loading is allocating a lot of memory just to pass vertex data around. The excuse is probably "mutithreading", however this is not necessary at all (see the last OptiFine for 1.7).
- the list goes on and on ...

The general trend is that the developers do not care that much about memory allocation and use "best industry practices" without understanding the consequences. The standard reasoning being "immutables are good", "allocating new memory is faster than caching", "the garbage collector is so good these days" and so on.

Allocating new memory is really faster than caching (Java is even faster than C++ when it comes to dynamic memory), but getting rid of the allocated memory is not faster and it is not predictable at all. Minecraft is a "real-time" application and to get a stable framerate it needs either minimal runtime memory allocation (pre 1.3) or controllable garbage collecting, which is just not possible with the current Java VM.

6. What can be done to fix it?
If there are 2 or 3 places which are wasting memory (bugs), then OptiFine can fix them individually. Otherwise a bigger refactoring of the Minecraft internals will be needed, which is a huge task and not possible for OptiFine.

7. Example
A sample log of GC activity with effective FPS for the GC lag spikes is available here.
- the average rendering FPS is about 50 FPS
- the GC lag spikes have effective FPS of 7-20
- there are 1-2 lag spikes per second caused by GC activity

tldr; When 1.8 is lagging and stuttering the garbage collector is working like crazy and is doing work which has nothing to do with the game itself (rendering, running the internal server, loading chunks, etc). Instead it is constantly cleaning the mess behind the code which thinks that memory allocation is "cheap".

I have a big problem that i cannot find the solution to.
I have this mod and mo creatures installed, no mobs are spawning, vanilla or mo creatures.
Please help!

By not finding the solution you mean you looked for one? It's a well known issue talked about just a few posts before yours. Mo Creatures does not recognize BWG biomes at the moment. This isn't a bug in BWG4.

Im a retard...

One rep point... because self awareness is a good thing.

If I'm *really* lucky, the 1.5.1 Railcraft and Thaumacraft (and for a bonus, the full release of Forestry, but theres a 1.5.1 beta of that that's working fine so far, so less crucial) will come out at about the same time as your reset-the-world update, so I can get all the world-gen in one go

Quote from Wolftein

Moving to ExtraBiomesXL since the dev here doesn't care about fixing stuff.

Dude.
New devs taking over the code of a large and significant mod right at the time of the Minecraft 1.5 update that included significant changes... you can't just snap your fingers and have everything instantly perfect.

IF its stealed code, HOW DARE YOU, if not, good job, I'm gonna check both codes and see if the code is the same
