    AntiDupl

    AntiDupl

    Search of similar and defective images on the disk.

    Typically, modern computer users have large collections of images in various formats. And then more these collections, then more likely to have the large number of duplicates. The natural desire of the user is to get rid of them. However, if the collection is large enough, do this manually is a very tedious and unproductive work. AntiDupl.NET program will help you automate this process. It can find and display duplicate images in the main graphic formats: JPEG, GIF, TIFF, BMP, PNG, EMF, WMF, EXIF, ICON, JP2, PSD, DDS and TGA. The comparison is based on the contents of the files, so the program can find not only almost identical, but similar images. In addition, the program can find images with some types of defects. AntiDupl.NET program is free and open-source software. It is simple to use, has high speed and accuracy of work, supports Russian and English interface.

    OpenVR SDK

    OpenVR SDK

    API and runtime that allows access to VR hardware

    OpenVR is an API and runtime that allows access to VR hardware from multiple vendors without requiring that applications have specific knowledge of the hardware they are targeting. This repository is an SDK that contains the API and samples. The runtime is under SteamVR in Tools on Steam. The OpenVR API provides a game with a way to interact with Virtual Reality displays without relying on a specific hardware vendor's SDK. It can be updated independently of the game to add support for new hardware or software updates. This means that you can access the position of the headset using only one API call and it works for all headset brands (Oculus, Mixed Reality, Vive, etc)! The API is implemented as a set of C++ interface classes full of pure virtual functions. When an application initializes the system it will return the interface that matches the header in the SDK used by that application.

    JarkViewer

    JarkViewer

    A lightweight, lightning-fast, and powerful image viewer

    JarkViewer is a lightweight, lightning‑fast image viewer for Windows 10/11 (64‑bit) that supports a wide range of modern image formats, from traditional JPEG/PNG to newer types such as AVIF, HEIC, JPEG XL, and various RAW files. It is designed as a native portable application with fully static linking, distributed as a single executable with no separate installer, making it simple to run from any folder or removable drive. The viewer handles static images, animated formats (GIF, animated WebP/PNG/APNG/JXL/AVIF), and special “live” photo types such as iOS Live Photos (.livp) and Android Motion Photos/Micro Videos, although audio playback for live photos is not yet supported. It also supports a broad set of RAW formats from various camera manufacturers, allowing photographers to browse their libraries without converting to JPEG first.

    OptiScaler

    OptiScaler

    OptiScaler bridges upscaling/frame gen across GPUs

    OptiScaler is an open-source modding tool designed to enhance graphics performance and flexibility in modern PC games by allowing users to replace or modify built-in upscaling technologies. Instead of relying on the upscaling method originally integrated by a game developer, the software intercepts the game’s rendering pipeline and redirects it to alternative technologies chosen by the user. This makes it possible to swap technologies such as NVIDIA DLSS, AMD FSR, or Intel XeSS even if the game only supports one of them by default. The tool effectively acts as a compatibility layer between the game engine and multiple upscaling frameworks, enabling cross-GPU access to features that might otherwise be restricted to specific hardware ecosystems. In addition to replacing upscalers, OptiScaler can enable frame generation features in titles that do not officially support them, improving frame rates and perceived smoothness during gameplay.

    Snapcast

    Snapcast

    Synchronous multiroom audio player

    Snapcast is a multiroom client-server audio player, where all clients are time synchronized with the server to play perfectly synced audio. It's not a standalone player, but an extension that turns your existing audio player into a Sonos-like multiroom solution. Audio is captured by the server and routed to the connected clients. Several players can feed audio to the server in parallel and clients can be grouped to play the same audio stream. One of the most generic ways to use Snapcast is in conjunction with the music player daemon (MPD) or Mopidy. The encoded chunks are sent via a TCP connection to the Snapclients. Each client does continuous time synchronization with the server, so that the client is always aware of the local server time. Every received chunk is first decoded and added to the client's chunk-buffer. Knowing the server's time, the chunk is played out using a system dependend low level audio API (e.g. ALSA) at the appropriate time.
