Since the 0.12 leaves performance is worse, even a simple forest biome crashes my game, same with windows 10 edition, i have worse performance in forests and taiga biomes than java edition

Still affects 0.15.4 / iPad 3rd gen.

Please respond and add the current version if you can reproduce this issue.

I highly doubt that the devs would want MCPE to be laggy.

Comment by Henry_Anonym [ 12/May/16 ]

I think this is more or less intended. The devs use a technique named "discarding fragments" in their GLSL shaders. Only the latest generation of devices can handle "discarding fragments" in a performant way, these can do it quite good though.
However, the performance problems are not cool. If you can modify the shaders, you can replace every line which says:

discard;

with

//discard;

. This, however, will make everything opaque and make you recognize another performance bug more easily (https://bugs.mojang.com/browse/MCPE-14383).

Yes, it affects 0.14 too

Comment by Luis Robles [ 01/Mar/16 ]

Does this issue still affects 0.14?, if so, please respond

Comment by Fiti Ball [ 08/Nov/15 ]

Yes, as i said the problem are the leaves, any other place runs fine

Have you tried turning your render distance down? I don't know how powerful of a device your phone ia, but that might make a difference.
