Based off latest generic CyanogenMod 12.1 nightly source
OTA updates via built-in CMUpdater
Vanilla CAF LA.BF.1.1.1_rb1.26 display HAL (improved display performance)
Vanilla CAF LA.BF.1.1.1_rb1.26 media HAL (improved video performance)
Vanilla CAF LA.BF.1.1.1_rb1.26 audio HAL (improved audio performance)
OxygenOS camera libraries (no camera bugs and improved camera performance)
Custom camera HAL I modified myself from CAF featuring:
-1080p video recording at 120 FPS
-Video recording at 90 FPS (for both 720p and 1080p)
-1080p video recording with the front-facing camera
-4K video recording at UHD and DCI resolutions
-More picture sizes than plain OxygenOS, such as 9.7MP 16:9
-JPEG quality is always set to 100% (pictures are very high quality)
Disabled Qualcomm performance daemon (CPU boosting is now handled completely by the driver I wrote)
2 CPU cores are not forced online all the time (saves power this way)
WiFi firmware and configuration from LG G3 (better WiFi performance and stability)
Many other misc. optimizations
Kernel features:
Based off latest CAF LA.BF.1.1.1_rb1.26 kernel source from Qualcomm
Most similar to Oxygen kernel (but there are many big differences in major Qualcomm driver subsystems)
Almost 100% pure CAF (very clean, shouldn't be any crazy stability or performance issues)
Removed lots of excessive debugging
Latest CAF LA.BF.1.1.1_rb1.26 prima (WiFi) drivers
Rewrote half of the Synaptics touchscreen driver (over 2500 lines of code modified; your touchscreen might work better)
Newest available Synaptics touchscreen firmware (the per-panel firmware, no battery drain:

Dynamic CPU input boost driver I wrote myself (makes the phone feel smooooth)
CPU underclocked to 1958MHz by default (you can disable this; see why I did this in the FAQ in the 3rd post)
Improved notification LED color (white doesn't have a blue tint)
Vibrator is automatically disabled when recording videos (so the buzzing noise doesn't get in the videos)
Custom thermal driver I wrote myself
LCD KCAL by Savoca
Westwood TCP congestion algorithm (set by default)
NTFS support
No BS patches, features, or compiler "optimizations"
Many other misc. optimization
