OptiScaler Client continues maturing as one of the easiest ways to upgrade all the different upscalers across various different games.

As a reminder on what OptiScaler actually is: it's a tool that lets you replace upscalers in games that already support DLSS2+ / FSR2+ / XeSS (), as well as manage frame generation in already mentioned games (either by replacing existing FG options or enabling it in DX12 games through experimental OptiFG). It also offers extensive customization options for all users, including those with Nvidia GPUs using DLSS.

From the release announcement for 1.0.7:

"This update introduces a major overhaul with comprehensive FSR 4 DLL Swapping & Imports (supporting INT8, FP8, and custom DLLs without requiring an OptiScaler install) alongside direct Frame Generation and Multi Frame Generation (MFG) support with multipliers up to x6, DLSS Enabler compatibility, and automated Streamline handling. The Manage window has also been heavily upgraded with direct controls for output upscaler technologies, quality presets, GPU spoofing, quick .ini previews, and support for OptiScaler Nightly builds (thanks to @FelipeGFA). Additionally, users can test experimental integrations for RenoDX and Nvidia Neural Rendering mod for AMD.

Behind the scenes, we have improved game-specific recommended configurations with auto injection selection and Luma UE support, refined FSR 4 behavior on RDNA 3, and boosted overall UI startup performance. Finally, critical stability and interface issues have been addressed, including a new software rendering fallback for older Windows 10 startup crashes, profile changes no longer discarding on exit, and various fixes for touch, high-DPI scaling, and Linux GPU badges."

It's open source and has Linux downloads available with full support making it easy to do whatever you want to get better performance and visuals from your games.
