Patch notes here from the updates I've done from the release of Build 50, there's some good stuff in here so give it a read

Patch Notes

General

• Reworked player movement, viewmodel bobbing/sway and weapon recoil to match Black Ops 1, I used a recompilation project which made it so I could see the exact code used in Black Ops 1/COD4 which should make this 1:1. Alongside this, gunplay should also feel identical, with almost every gun feeling the same they did in their original games
• Replaced Unreal Engine’s default graphics scalability settings with custom presets:
  • Potato
  • Low
  • Medium
  • High
• This custom preset change should improve performance and visuals, since the default scalability settings was changing stuff that simply didn't matter
• Re-enabled texture streaming to significantly reduce RAM and VRAM usage, with minor texture pop-in as a trade-off.
• Reworked weapon asset loading to preload weapon assets at startup, reduce memory usage, and improve stability on lower-end systems.
