This needs to be fixed out of all the other ones so far. No crashes so far, and it seems that when this bug happens the RAM usage is unusual high taking up to 80%+ and my PC slows down. I think the VBO option is the whole problem of this as nothing else does this.
I can confirm that Birch are yielding less Sapling's for every harvest starting from 1.7 and up, what else explains my Birch Tree Sapling numbers getting smaller? But, others seem to not be affected, or why.
I tried Java 7 and 8 and even 9 snapshots, no version have no different effect. I used all the internal settings that came with 1.8 and no noticable difference. Funny how they said this is going to support Multi-core yet Both 1.7.10 and 1.8 only use "40%" of my CPU, I guess 1.8 does not have multi-core support as well. But RAM usage has gone from 600MB-1GB to sometimes MAX out my RAM. There is nothing wrong with my PC as "MANY" games except for minecraft seems to benefit with the optimizations for computers performance. I would like my 150FPS back on 1.8 instead of the 40 and below and constant stuttering (and that's with all the settings turned down).
Specs:
MOBO: ASROCK Z77 PRO3
CPU: i5 3570K @ 4.6Ghz (Stable and not overheating) (Also if this game is CPU intensive, why does it only use 40% and not get what it really needs? Because most games use "more" CPU like than just get stuck at 40% and never use the rest.)
GPU: HD Radeon 7850 @ 1.1Ghz, Memory @ 1500Mhz (Stable and not overheating)
RAM: G.Skill 8GB (2x4GB sticks)
OS: Windows 7 Home Premium (Nothing wrong with it)
HDD: 1TB (Normal, no errors, mostly free from traffic)
PSU: 500W
(Note: underclocking does NOT help)
