OptiScaler

OptiScaler is a tool that allows you to replace upscalers in games that already support DLSS2+, FSR2+ or XeSS. It also enables frame generation in those same games through integrations such as Nukem's dlssg-to-fsr3 or OptiFG. It offers advanced customization options for users with Nvidia, AMD and Intel GPUs.

Upscaler replacement. Allows swapping upscaling technologies in games that already implement some native solution. For example, replacing DLSS with FSR 3.1 or XeSS in titles that only include one option.
Frame generation. Implements experimental frame generation via OptiFG (based on FSR3) or integration with Nukem's dlssg-to-fsr3 for games with native DLSS-FG.
Cross-platform support. Works with DirectX 11, DirectX 12 and Vulkan graphics APIs, including specific configurations for each upscaler version.
FSR4. Includes experimental support for FSR4 on RDNA4 hardware, with updated libraries.
Advanced customization. Offers detailed adjustments such as RCAS & MAS, output scaling, DLSS presets, ratio overrides and DRS.
Latency reduction. Integration with Fakenvapi for Reflex hooking, Anti-Lag 2 (RDNA1+) or LatencyFlex (LFX).
Extended compatibility. Support for UWP games like Minecraft, with automatic path detection and critical files such as nvngx_dlss.dll.
Informative overlay. Shows real-time technical data such as active upscaler, input source and implementation details.
Incompatibility management. Includes specific quirks for problematic games like No Man's Sky, Red Dead Redemption 1 and Cyberpunk 2077.
SDK updates. Option to update Agility SDK and use native FSR 3.1 libraries.
HUD fixes. Experimental solutions for interface overlay issues in frame generation.
Performance optimizations. Improvements in memory management, crash prevention and compatibility with overlays such as Steam/Epic.

OptiScaler started development in 2023 as a project to expand upscaling options in games with limited support. The current version (v0.7.7) is written primarily in C++ with HLSL components for graphics integrations. Development is led by Daria with key contributions from TheRazerMD, PotatoOfDoom and FakeMichau, focusing on compatibility across GPU architectures.
