Use this, replace spoutcraft-launcher.jar with .exe of minecraft launcher. Set xmx to be 1/2 or more of your ram (depending if you want other apps work well), also set parallelGCThreads to equal total number of cores on your PC.If something goes wrong remove -XX:+UseBiasedLocking -XX:+TieredCompilation, and if you'll have troubles and graphical artifacts try replacing noddraw=false d3d=true opengl=false to switch onto direct 3d rendering.There, saved you 5 hours of looking through java docs.
-Dsun.java2d.d3d and -Dsun.java2d.noddraw are the same and useless.
I also add OptimizeStringConcat and UseCompressedStrings as addition to UseStringCache.UseFastAccessorMethods can actually hurt your performance. (here)
You can't use CMSIncrementalPacing without UseConcMarkSweepGC and he is anyway better than the UseParallelOldGC.
I use -Xincgc because he doing both plus UseParNewGC. -Xss128M is an ultra overkill which my computer can't open (default is 512K!!!).
I have a laptop with theses specs
- nividia gt750m gddrr5 2gb
- 8gb ddr3 ram
- 1tb hdd 5400 rpm
Plzz dont say my rig is bad because i had a worse laptop and it got better fps in minecraft
Basically i only get about 90-120 fps (not a big deal as its smooth) but when i try to record minecraft it drops to 30-40 and its very choppy and unplayable as i upload mcsg (MineCraft Survival Games). on my old laptop with a i5 4200u and gt740m 4gb ram and i got 90-100 fps while recording i use bandicam to record.
The Meaning of Life, the Universe, and Everything.
Thanks a lot, I sent my computer back to the manufacture and they said everything was fine I went from ~10 FPS on a highly modded mod pack to 179 because of the setting to dedicated video card. I wasn't able to find minecraft.exe but just allowing Java fixed the problem just mad now I went 3 weeks without that computer and they weren't smart enough to do that lol
span>2058mb is A LOT of new mobs like mo creature, humans+, pokemobs, etc. Also if you have out of memory problems. 4096 is unnecessarily high, but it is possible. These are in megabytes so 1024 is a gigabyte of ram. Adding more memory than default may help if you have a lot of spare RAM.
Instead of allocating 2048mb (2gb) You can allocate 1536mb (1.5gb) with little to no difference.
