Minecraft Forums

Im using 1.7.10 modded minecraft and i keep getting the lag spikes were
happening before i went to another dimension but the block breaking lag
started after i left wakanda from the superheroes unlimited mod Here
are my number of mods=49 and my pc specs 8gb ram 2.8 ghz processing
speed and i have optifine and fastcraft and optifine is on the best
settings i also have 4gb ram allocated for minecraft render distance is
12 plz help ps:fps has been fine.

Thanks ill try it

how big is your modpack? or how much mods do you have?

oops

ignore what i said

Use a modpack with less dimensions it will definitely decrease lag spikes and if you havent allocate more ram to your server.

mods=49 my pc specs 8gb ram 2.8 ghz also have 4gb ram allocated

Its not a problem with dimensions cause i can play both crazy craft 3 and crainer craft i tried what mazecraft said it helped but then the lag started again after a few minutes in the nether

im also having another problem a diffrent modpacks that has been working fine suddenly starts crashing after i leave the world plz help here is the report:---- Minecraft Crash Report ----
// Oops.

Issue #1: try taking out -XX:+CMSIncrementalMode (if you haven't already, as it plays with dual/quad/multi core PC's)

Issue #2: I couldn't tell you, haven't seen an error like this.

what do you mean try taking out -XX:+CMSIncrementalMode [/i]tell me how please

Go to your launcher, click the Edit Profile button, check the JVM Arguments box, and delete +CMSIncrementalMode from the JVM Arguments box.

I dont have that in my java arguments but i have another issue when i go to nether no wither skeletons are spawning or magma cubes or ghasts only thing spawning are zombie pigman and blazes and modded mobs

ok now some wither skeletons are spawning but no ghasts or magma cubes are

Sometimes, when you load a world, something (like modded mobs) can take control of default mob spawns (had this issue with pixelmon and passive mobs) and stop them entirely. Try adding a mod such as a mob spawn control mod.

thanks still having a lag issue if u could help with any ideas u think would work.

Have you tried updating Java/Are you running the right bit version (x32 or x64) Java?

Also, one of your Core API's doesnt seem to want to properly co-operate with Optifine.

ok thanks yes im on java 64 and 8 ill check out the cores one more thing when i try to play crainer craft once i load the world it says fatal error and takes me to multiplayer screen no crashing though plz help

never mine i fixed crainer craft having an issue with crazy craft 3 crashing when i load my world btw ive been using this world for a while
