re4_tweaks - Fixes and tweaks for Resident Evil 4 UHD

[]Fix blurry image - Fixes a problem related to a vertex buffer that caused the image to be slightly blurred, making the image much sharper and clearer.

[]Enable GC blur - Restores DoF blurring from the GC version, which was removed/unimplemented in later ports.

[]Enable GC scope blur - Restores outer-scope blurring when using a scope, which was removed/unimplemented in later ports.

[]Borderless window - Whether to use a borderless-window when using windowed-mode.

[]Separate volume sliders - Allows seperate adjustment of background music/sound effect/cutscene volume.

[]Mouse turning - Makes the mouse turn the character instead of controlling the camera, similar to Resident Evil 5.

[]Raw mouse input - Makes the game use Raw Input for aiming and turning. Greatly improves mouse input by removing negative/positive accelerations that were being applied both by the game and by Direct Input.

[]Replace framelimiter - Implements a new reduced-CPU-usage FPS limiter.

[]Vulkan renderer - Enables the use of the DXVK-based vulkan renderer, which provides better performance on newer hardware.

[]Multithread Fix - Enables fixes for multithreaded DirectX9, giving a slight performance boost.

[]Restore demo videos - Restores the playback of demo videos that play when the game is idle at the main menu or the "press any key" screen for about 20 seconds. More info in the config menu/.ini file.

[]NTSC Mode - Unlocks minor difficulty boosts previously exclusive to the NTSC console versions of RE4.

[]DetachCameraFromAim - When using the "Modern" mouse setting, the game locks the camera position to the aiming position, making both move together. Although this is the expected behavior in most games, some people might prefer to keep the original camera behavior while also having the benefits from "Modern" aiming. Enabling this will also restore the horizontal aiming sway that was lost when the devs implemented "Modern" aiming.

[]Fix sniper zoom - When playing with keyboard and mouse, this fixes an annoying bug which would cause your camera to be off-center after you zoomed in with a sniper rifle.

[]Fix sniper focus - When zooming in and out with the sniper rifle using a mouse, this option makes the "focus" animation look similar to how it looks like with a controller.

[]Fix "Retry/Load" mouse selector - Prevents the game from overriding your selection in the "Retry/Load" screen when moving the mouse before confirming an action. This bug usually causes people to return to the main menu by mistake, when they actually wanted to just restart from the last checkpoint.

[]Key Icon Fallback - Game is missing icons for certain keyboard languages, normally they would be made invisible, but can now have English equivalents shown instead.

[]Allow reload without aiming - Removes the need to be aiming the weapon before you can reload it. KB/M and Controller supported. (DInput untested). Also provides an extra option to disable the camera zoom when you reload weapons.

[]Flip items in your inventory using the keyboard - Creates key bindings to flip (not just rotate) items when playing with a keyboard and mouse, just like you can do if you play with a controller.
