best JVM arguments for the mod

[c4mp3r-87]

i need some help with the JVM to run the mod smoothly, i already copied some commands from youtube, but i think there may be better commands to use.

the current JVM i use are:
-XX:+UseG1GC -XX:+UnlockExperimentalVMOptions -Xmx8G -Xms8G -XX:+DisableExplicitGC -XX:ParallelGCThreads=12 -XX:+UseNUMA -Dfml.ignorePatchDiscrepancies=true -Dfml.ignoreInvalidMinecraftCertificates=true -XX:MaxGCPauseMillis=50 -XX:SurvivorRatio=8 -XX:TargetSurvivorRatio=90 -XX:MaxTenuringThreshold=15 -XX:SoftRefLRUPolicyMSPerMB=6000 -XX:ReservedCodeCacheSize=1024m -XX:+UseCodeCacheFlushing -Dorg.lwjgl.opengl.Window.undecorated=true

my PC specs:
-32GB ram
-AMD ryzen 5 4600G with Radeon Graphics

My FPS varies between 30 ~ 120(standing still) , and sometimes i have some huge LAG spikes
i don't use optifine as it cause some strange bugs sometimes

in game i set all the graphic configs to fancy and render distance on 8

Actually scratch that, 8 gb is a bit too much because after a certain point java gc will start giving diminishing returns and start performing worse

so, 4Gb is enough?
