In order to play Assassin's Creed Brotherhood through to Rogue you currently need:
PPU Interpreter
Enable Accurate ppu non-java mode
Disable non java mode fixup
SPU Xfloat accuracy set to accurate
Ordered and atomic FIFO accuracy.

Assassin's Creed 3 (BLUS30991) Crashes with above settings, regardless.

Double check that the empty folder ASSASSIN_ISO exists inside PS3_GAME\USRDIR.
Your game won't play without that directory when your game is a disc.

when i apply those changes the game do not freeze anymore but i get a lot of dropframes instead.

The settings are accuracy settings. You will experience horrible performance because you are trading the performance for the accuracy required for the game to load without freezing. It can go anywhere from decent 28fps consistency to sub 12 fps frequently.

isn't there any solution or settings to minimize that horrible performance?

ok ,thank you for everything ,I really appreciate it.

I am testing games as working with only the ppu Interpreter (maybe atomic rsx fifo is needed) but you don't need my other setting suggestions that are old.

I made the edits to the wiki. I made the comment to this github issue.
The game's WERE just fine with ppu Interpreter + their ocean fixes.
But then amidst the PRs and merge, merge, merge somewhere somehow the games freeze again. And I shouldn't have done anything.

RPCS3.log
I logged the kernel and found
Memory Containers (1)
Memory Container 0x3f000000: Used: 0x1000000/0x1000000 (16.00/16.00 MB)
Does this have any effect on the freezes?

To play Assassin's Creed Brotherhood through to Rogue you currently need: PPU Interpreter Enable Accurate ppu non-java mode Disable non-java mode fixup SPU Xfloat accuracy set to accurate Ordered and atomic FIFO accuracy.

I can validate those settings still fix the series random freezes and here is a log without those settings and logging kernel after freeze.
