64Bit-Java Required for Far rendering?

[nsanexer0]

Why the sudden change, I'm guessing 64-Bit java is better at handling mass of code and slipstreaming everything really nicely.

However, pre-1.9 releases I've always been able to play on max rendering + 3x view distance (Using opti-mine for graphical boosts and lagspike fix)

Now I get lagged to death on far render distance and then it crashes with OOM errors -____-
