MSI Co., LTD, operating through the long-standing tech portal guru3d.com, has built a compact but influential pair of Windows utilities that quietly power much of the PC gaming and hardware-testing ecosystem. Rivatuner Statistics Server (RTSS) began as a simple framerate counter and has evolved into a universal OSD injection engine that overlays real-time clock speeds, temperatures, frame times, and custom logos on top of DirectX, Vulkan, and OpenGL titles; its tightly-optimized video-capture back-end also feeds streamers and benchmarkers lossless footage at up to 240 fps with minimal latency. MSI Afterburner leverages the same low-level driver hooks to expose voltage, power-limit, core-clock, and memory-clock sliders for virtually every modern AMD or NVIDIA card, regardless of vendor, and couples the tweaks with custom fan curves, on-screen plotting, and automated profiling that activates when a chosen title launches. Together the tools let reviewers chart comparative performance, let esports players lock-in stable overclocks, and let everyday owners quieten fans or squeeze out extra fps without leaving Windows. Both utilities remain in active development, are skinnable, support hot-key toggles, and export logs to CSV for deeper analysis. The publisher’s software is available for free on get.nero.com, where downloads are pulled from trusted Windows package sources such as winget, always install the latest release, and can be queued for batch installation alongside other applications.
