* video_core: NVIDIA DLSS through NVIDIA Streamline in place of a game's DLSSDuck91210 hours1-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds a Graphics setting, "Use NVIDIA DLSS in place of a game's DLSS" (nvidia_dlss, off by default). When it is on, in Windows builds configured with EGLANTINE_STREAMLINE_SDK, the evaluation Eglantine already replaces with FSR 3.1 goes to NVIDIA DLSS on GeForce RTX cards, with the same inputs (colour, depth, motion vectors, jitter). When DLSS can't run, FSR 3.1 runs as before. Only Streamline's MIT-licensed headers are compiled in; nothing of NVIDIA's is linked or shipped. At run time Eglantine looks for sl.interposer.dll in the user folder's "streamline" folder (or EDEN_STREAMLINE_DIR, or "streamline" next to the executable), checks its Streamline signature and starts Streamline with manual hooking. Streamline's plugins come from that folder or the NVIDIA app's downloads. DLSS itself is nvngx_dlss.dll in the same folder, else the newest DLSS 310 or later that the NVIDIA app has downloaded, checked for NVIDIA's Authenticode signature and copied as streamline/nvidia-app/nvngx_dlss.dll. Like other tools that call DLSS outside a game, it uses its own fixed project id with the custom engine type. - Preset K for all modes (EDEN_NX2_DLSS_PRESET overrides it): the default Performance model (M) and L draw thin dark horizontal lines in some frames at 2x resolution scale; K doesn't. - HDR input with auto exposure; the mode follows the render/output ratio. - Buffer device address stays enabled when DLSS needs it, for DLSS only. - The upscaler waits for the device instead of submitting when it is destroyed: by then the game's channels are released, and a submit read the state tracker's stale flags (a crash when stopping a game). With the setting off, or in builds without the SDK path (the setting is hidden there), nothing changes. Testing: Windows 11, RTX 5080, Fire Emblem: Fortune's Weave docked at 1x (720p -> 1440p) and 2x (1440p -> 2880p), CLI runs and GUI play, stopping and restarting games with DLSS on. Not tested on other GPUs or games. Assisted-by: Claude Opus 5.5 (implementation, debugging) Signed-off-by: Duck912 <350528965+Duck912@users.noreply.github.com>

* [vulkan, android] Initial implementation of LSFG-VK (#4263)CamilleLaVey2026-08-171-1/+7
| | | | | | | | | | | | | Pretty much self explanatory, own implementation based on LSFG-VK available with some additional reverse engineer work for the actual use of shaders inside Lossless.dll, we don't store/ bundle any tools that bypass security and self ownership: to use this feature is required to own your own copy of Lossless Scaling and I encourage to support developers behind this work.

* [vk] Unify RAII in Vulkan (#2679)Ribbit2025-10-081-7/+3
| | | | | | | | | | | This PR consolidates Vulkan RAII on video_core/vulkan_common/vulkan_wrapper.h’s vk::Handle and remove the unused duplicate src/video_core/vulkan_common/vulkan_raii.h, reducing confusion and maintenance. Swapchain now uses RAII‑managed per‑image semaphores and clears them in Destroy(), providing correct present synchronization and automatic cleanup. Expected result: simpler lifetimes, fewer leak risks, and more stable presentation with negligible overhead.

Ensures compatibility with color formats and adds fallbacks for depth/stencil. • Memory fix misallocation: Adds checks for null/zero-length operations in memory management and improves cleanup to avoid crashes (Related to crash issues due to misallocation, RP5 and 865) • Vulkan Initialization (RAII): this almost rewrites the way vulkan initializes to avoid crashes, using a correct order now (thanks @crueter for the initial fix) •Please check before merging: - Test MSAA workflows (especially color/depth transitions and low memory cases). - Verify memory operations (e.g., unmapping zero-length regions). - Check Vulkan object lifetimes and platform-specific behavior. - Check others plataforms beyond android Why is everything in one PR?

* video_core: Reimplement the buffer cacheReinUsesLisp2021-02-131-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Reimplement the buffer cache using cached bindings and page level granularity for modification tracking. This also drops the usage of shared pointers and virtual functions from the cache. - Bindings are cached, allowing to skip work when the game changes few bits between draws. - OpenGL Assembly shaders no longer copy when a region has been modified from the GPU to emulate constant buffers, instead GL_EXT_memory_object is used to alias sub-buffers within the same allocation. - OpenGL Assembly shaders stream constant buffer data using glProgramBufferParametersIuivNV, from NV_parameter_buffer_object. In theory this should save one hash table resolve inside the driver compared to glBufferSubData. - A new OpenGL stream buffer is implemented based on fences for drivers that are not Nvidia's proprietary, due to their low performance on partial glBufferSubData calls synchronized with 3D rendering (that some games use a lot). - Most optimizations are shared between APIs now, allowing Vulkan to cache more bindings than before, skipping unnecesarry work. This commit adds the necessary infrastructure to use Vulkan object from OpenGL. Overall, it improves performance and fixes some bugs present on the old cache. There are still some edge cases hit by some games that harm performance on some vendors, this are planned to be fixed in later commits.
* gpu: Report renderer errors with exceptionsReinUsesLisp2021-02-131-26/+17

* renderer_vulkan: Rename Vulkan memory manager to memory allocatorReinUsesLisp2021-01-151-2/+2

| | | | | | | The "VK" prefix predates the "Vulkan" namespace. It was carried around the codebase for consistency. "VKDevice" currently is a bad alias with "VkDevice" (only an upcase character of difference) that can cause confusion. Rename all instances of it.
