If/when you exceed the ability of the gfx drivers to keep the textures on the video card and/or cache them in system memory, Minecraft's fps will start to suffer.Īs you wander through twilight forest, you are exposed to more biomes. As you proceed through the game (and twilight forest) more and more textures are allocated. the sources of lagieness in Minecraft do not usually include garbage collection: The simple fact is that Minecraft does NOT have smart texture (memory) management. big enough that minecraft doesn't crash) for best performance. The only flags you *need* to pass to java are -Xmx and -XX:MaxPermSize, and even these should generally be kept as low as possible (i.e. Java has now been through a rather lot of updates and revisions and the default settings for most of these things are usually optimal. I am, frankly, not expecting anything to come of the experimentation. Perhaps there are some better or additional flags that I can use for Java?Īny tips or advice is welcome. So basically I'd like to know if this is a known issue and if there is a solution to this problem. There were not many entities as far as I could see and nothing spectacular in the profile runs. I'm using Opis but nothing special could be seen there. The lag is complely gone and I can play as normal. If I exit MineCraft and restart my game then all is fine. My entire system is slowing down to a crawl until I exit MineCraft. When I switch to other programs (chromium, shell. I get about 5 seconds for every frame and even when I pause the lag doesn't stop. However, when I explore TF and new chunks have to be generated it seems things get very bad.
Even in the Twilight Forest I basically have no lag whatsoever. So as I told above I basically have really very good performance everywhere. I know I'm not using FTB right now but I have a mostly similar set of mods and I think many people here are probably very knowledgable on how to setup a good MineCraft setup on Linux. Xmx4G -Xms1736M -server -XX: PermSize=150M -XX:MaxPermSize=256M MineCraft 1.6.4 with 163 mods (custom mod pack but based on many of the mods that are also in popular FTB packs). I will describe my problem in more detail here. I know that TF is a heavy mod which has the potential of adding a lot of lag but I feel that my problem is different because I am actually having REALLY very good performance in TF all the time *except* when I start exploring and (presumably) when lots of new chunks are generated. Hi all, I'm having a bit of a performance issue in Twilight Forest.
