Hi, recently started playing (started as a summon druid) and noticed my framerate would tank in bigger packs. Began troubleshooting by lowering graphics settings, tweaking driver configs, closing other apps, etc. Nothing helped. Next I searched in discord for similar issues, and I noticed a few other people hinting at creepers being a culprit of this (I am only speaking from the perspective of someone playing a summon druid as that is all I've played in this mod so far). I proceeded to do some testing on shenk and his relatively dense packs.
Test 1: All summons from the tree. Framerate drops to sub 30s during the fight.
Test 2: No poison creeper. Framerate only drops to mid-40s.
Test 3: No poison and solar creeper. Framerate does not drop at all.
Test 4-10: Same as test 3, framerate never dipped.
Something about the ground DoT effect of these creepers is causing framerates to take a big hit I suspect?
Note that carrion creeper had no effect on the framerate.
