KOEI Tecmo and Team Ninja Release Rise of the Ronin Patch from April 10, which includes a number of performance optimizations.
The April 10 update, also known as patch 1.09.0.3, includes optimization improvements for rendering to reduce overall VRAM usage. It also includes GPU performance optimization improvements for ambient occlusion and upscaling. So, in theory, the game should run better than before.
The developers have also added a new graphics setting, Dynamic FPS Adjustment. This option will dynamically change the frame rate based on performance to ensure a consistent gaming experience.
It's also worth noting that the patch fixes a strange issue where CPU usage could increase significantly if the audio output settings were set to "Surround" or "3D Audio Effects" while spatial audio was disabled in the Windows sound settings. So CPU usage should now be lower with these settings.
Moreover, the April 10 patch contains a number of bug fixes. For example, it fixes issues with visual noise during a certain scene. It also fixes an issue where the game would freeze when loading after restoring public order. Additionally, it fixes an issue where the game would occasionally crash when switching languages mid-game.
