– Fixed a bug if no ToSort directory exists, or if there is already a files with the same name in tosort.
– No longer load DAT if the DAT contains no files.
– Changed the encoding used for ZIP filenames and now only using unicode zip filenames if the filename does not fit the encoding 437.(Original IBM PC encoding.)
– Using a newer .net version that permits //?/, so can add //?/ and call the .net function now, instead of having to call the file kernel dll’s.
– Switch from ILMerge to ILRepack to make the single .exe files for the releases. ILMerge does not work with .net core, which I plan to try using at some point.
– Fixed a crash bug in 7z files when there is a zero byte file by itself in a 7z file.
– Added « File | Clear Settings and Quit » option to VGBA-Windows.
– Fixed small windows behavior in VGBA-Windows.
– Fixed window position behavior in VGBA-Windows.
– Saving physical joystick/gamepad selection in VGBA-Windows.
Vulkan/OpenGL: Further improvements to GPU buffer cache
# New in 1.20.0b:
Vulkan/OpenGL: Various fixes and smaller optimizations in the new GPU buffer cache
Vulkan: Added support for texture format D32_FLOAT_S8
Fixes the black screen issue in Ninja Gaiden 3
input: Fixed an issue where configured DirectInput controllers could cause Cemu to crash at boot or when launching a game
# New in 1.20.0:
Vulkan/OpenGL: New GPU buffer cache
Technical details:
– Buffer cache exists to emulate unified memory (PCs generally have dedicated VRAM unlike the original console which shares RAM between CPU and GPU)
– Old buffer cache implementation had separate caches for different types of GPU buffers (attribute, uniform, streamout)
New implementation has one central cache for all buffer types, avoiding redundancy if data overlaps
– Much lower PCIe bandwidth usage since only actually modified data is transferred
– Very high accuracy and almost no CPU overhead since buffer invalidation relies on hints (cache flushes etc.) instead of using polling with heuristics
Known improvements (as of 1.20.0c):
– Better performance in many games
– GPU buffer cache accuracy option has been removed since the new cache doesn’t require tweaking
– All polygon explosions in Sonic Boom are fixed
– DKC Tropical Freeze Level 2-1 should no longer have distorted background models but may still crash
– Broken particles in Breath of the Wild are fixed
Known issues (as of 1.20.0c):
– Flickering or distorted models in Xenoblade Chronicles
– Rare and random flickering or distorted geometry in all games under Vulkan (likely vendor specific)
general: Added import/export option for saves in title manager
general: The quickstart guide will automatically fill in the mlc folder if it is known from a previous Cemu installation
general: Updated language files
Vulkan: Added support for nearest neighbor up/downscaling filter
