      ATTENTION Forum Database Breach   03/04/2019

      There has been a breach of our database. Please make sure you change your password (use a password manager, like Lastpass).
      If you used this password anywhere else, change that too! The passwords themselves are stored hashed, but may old accounts still had old, insecure (by today's standards) hashes from back when they where created. This means they can be "cracked" more easily. Other leaked information includes: email, IP, account name.
      I'm trying my best to find out more and keep everyone up to date. Discord (http://invite.gg/TerraFirmaCraft) is the best option for up to date news and questions. I'm sorry for this, but the damage has been done. All I can do is try to make sure it doesn't happen again.

Bad Performance and Bad seeds

4 posts in this topic

I recently started playing terrafirmacraft again, and this time i`m only getting bad seeds. I`m aways spawning in a medium size island whit no fresh water and no ores laying around. And my performance has aways been horible, whit constant lag spikes and bad fps, but when the mod isn`t installed i get max frames and no lag spikes.

 

Specs:

AMD FX-6100 Six-Core Processor (6 CPUs), ~3.3GHz

GA-78LMT-S2P

GeForce GTX 760

16 gigs of ram (1333MHz)

 

Java: (build 1.8.0_31-b13)

Forge Mod Loader: 7.10.85.1291

Minecraft Forge: 10.13.2.1291

Optifine: 1.7.10_HD_U_B5

TFC: 0.79.15

Try using Fastcraft. Also Kitty has posted JVM arguements to try in a number of new posts in this section. Because TFC has sea level at 144 it is much heavier to run as there are a lot more blocks to render.

i already tried fastcraft, and my JVM arguments are like this atm:  -Xmx3072M -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn3072M

Are you sure you are using 64bit java? Have you tried with Fastcraft and without optifine installed? Optifine can cause more lag that it helps with in modded Minecraft.

 

Your JVM arguments should be this:

-Xmn1G -Xms1G -Xmx2G -XX:NewSize=512M -XX:SurvivorRatio=2 -XX:+DisableExplicitGC -XX:ParallelGCThreads=6 -d64 -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalPacing -XX:+AggressiveOpts

Allocating too much memory can cause just as much lag as not allocating enough. Start with the max set to 2G. If you're still having issues, then increase it to 4G, but do not change the Xmn or the Xms arguments.
