Extreme Injector
DLL injector for gaming and other uses
Extreme Injector is a software tool commonly used to inject Dynamic Link Libraries (DLLs) into other processes running on a Windows system. Often used in gaming and software development, this tool allows users to modify or add custom functionality to a target application by "injecting" DLL files, which can influence the application's behavior or provide additional features. Extreme Injector is popular in the gaming community for enabling modifications or "mods" in games, but it also has potential misuse in game cheating and malware deployment, as it allows for altering applications in ways the original developers may not have intended. -

Roblox FPS Unlocker
FPS Unlocker for Roblox
FPS Unlocker for Roblox. Download the latest release, extract rbxfpsunlocker-x64.zip into a folder, run the exe before or after starting Roblox, and enjoy the beautiful frames available. All detections are false positives. Internally, RFU "tampers" with running Roblox processes in order to uncap framerate and can appear as suspicious to an anti-virus. For reasons unbeknownst to me, 32-bit builds of RFU garner many more false positive detections than 64-bit builds and are no longer included in new releases. If you don't trust me, feel free to download the repository, review the source code, and compile the project yourself with Visual Studio 2019. Otherwise, add an exception to your anti-virus for rbxfpsunlocker.exe (or the folder it is in). -

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. -
