OptiScaler v.0.7.7 - Dla Gracza - Download

OptiScaler is an open-source tool made by cdozdil.

Description:

OptiScaler is a tool that lets you replace upscalers in games that already support DLSS2+ / FSR2+ / XeSS, now also supports enabling frame generation (through OptiFG or Nukem's dlssg-to-fsr3).

While previously only DLSS2+ inputs were supported, newer versions also added support for XeSS and FSR2+ inputs (with some caveats

). For example, if a game has DLSS only, the user can replace DLSS with XeSS or FSR 3.1 (same goes for an FSR or XeSS-only game). It also offers extensive customization options for all users, including those with Nvidia GPUs using DLSS.

Key aspects of OptiScaler:

1. Enables usage of XeSS, FSR2, FSR3, FSR 4 and DLSS in upscaler-enabled games
2. Allows users to fine-tune their upscaling experience with a wide range of tweaks and enhancements (RCAS & MAS, Output Scaling, DLSS Presets, Ratio & DRS Overrides etc.)
3. Since v0.7.0+, added experimental frame generation support with possible HUDfix solution (OptiFG by FSR3)
4. Supports Fakenvapi integration - enables Reflex hooking and injecting Anti-Lag 2 (RDNA1+ only) or LatencyFlex (LFX) - not bundled
5. Since v0.7.7, support for Nukem's FSR FG mod dlssg-to-fsr3 has also been added - not bundled
6. For a detailed list of all features, check Features

Important

Always check the Wiki Compatibility list for known game issues and workarounds.

Also please check the Optiscaler known issues at the end regarding RTSS compatibility

How it works?

OptiScaler implements the necessary API methods of DLSS2+ & NVAPI, XeSS and FSR2+ to act as a middleware. It interprets calls from the game and redirects them to the chosen upscaling backend, allowing games using one technology to use another one of your choice.

Note

Pressing Insert should open the Optiscaler Overlay in-game and expose all of the options (shortcut key can be changed in the config file).

Which APIs and Upscalers are Supported?

Currently OptiScaler can be used with DirectX 11, DirectX 12 and Vulkan, but each API has different sets of upscaler options.

OptiFG currently only supports DX12 and is explained in a separate paragraph.

For DirectX 12

1. XeSS (Default)
2. FSR2 2.1.2, 2.2.1
3. FSR3 3.1 (and FSR2 2.3.2)
4. DLSS
5. FSR4 (Preliminary support)

For DirectX 11

1. FSR2 2.2.1 (Default, native DX11)
2. FSR3 3.1.2 (unofficial port to native DX11)
3. XeSS 1.x.x, FSR2 2.1.2, 2.2.1, FSR3 3.1 & FSR2 2.3.2 (via background DX12 processing)
4. DLSS (native DX11)

For Vulkan

1. FSR2 2.1.2 (Default), 2.2.1
2. FSR3 3.1 (and FSR2 2.3.2)
3. DLSS

INSALLATION:

[Automated]

1. Extract all of the Optiscaler files by the main game exe (for Unreal Engine games, that's usually the win_shipping.exe in one of the subfolders, generally <path-to-game>\Game-or-Project-name\Binaries\Win64\, ignore the Engine folder)

2. Try the OptiScaler Setup.bat script for automating the renaming process.

3. If the Bat file wasn't successful, please check the Manual steps.

[Manual]

Nvidia

Step-by-step installation:

1. Extract all Optiscaler files from the zip by the main game exe (for Unreal Engine games, that's usually the win_shipping.exe in one of the subfolders, generally <path-to-game>\Game-or-Project-name\Binaries\Win64\, ignore the Engine folder).

2. Rename OptiScaler's OptiScaler.dll (for old versions, it's nvngx.dll) to one of the supported filenames (preferred dxgi.dll, but depends on the game)

1

Note

For FSR2/3-only games that don't have DLSS (e.g. The Callisto Protocol or The Outer Worlds: Spacer's Choice Edition), you have to provide the nvngx_dlss.dll in order to use DLSS in Optiscaler - download link e.g. GamePressure

AMD/Intel

Step-by-step installation:

1. Extract all Optiscaler files from the zip by the main game exe (for Unreal Engine games, that's usually the win_shipping.exe in one of the subfolders, generally <path-to-game>\Game-or-Project-name\Binaries\Win64\, ignore the Engine folder)

2. Rename OptiScaler's OptiScaler.dll (for old versions, it's nvngx.dll) to one of the supported filenames (preferred dxgi.dll, but depends on the game)

1

3a. Either locate the nvngx_dlss.dll file (for UE games, generally in one of the subfolders under Engine/Plugins), create a copy, rename the copy to nvngx.dll and put it beside Optiscaler

3b. OR download nvngx_dlss.dll from e.g. GamePressure repo if you don't want to search, rename it to nvngx.dll and put it beside Optiscaler

Check the screenshot for proper installation

[Nukem's dlssg-to-fsr3]

1. Download the mod's regular version - dlssg-to-fsr3 NexusMods or dlssg-to-fsr3 Github

2. Put the dlssg_to_fsr3_amd_is_better.dll in the same folder as Optiscaler (by the main game exe) and set FGType=nukems in Optiscaler.ini

3. For AMD/Intel GPUs, Fakenvapi is also required when using Nukem mod in order to successfully expose DLSS FG in-game.

[Fakenvapi]

0. Do not use with Nvidia, only required for AMD/Intel

1. Download the mod - Fakenvapi

2. Extract the files and transfer nvapi64.dll and fakenvapi.ini to the same folder as Optiscaler (by the main game exe)

Anti-Lag 2 only supports RDNA cards and is Windows only atm (shortcut for cycling the overlay - Alt+Shift+L). For information on how to verify if Anti-Lag 2 is working, please check Anti-Lag 2 SDK. Latency Flex is cross-vendor and cross-platform, can be used as an alternative if AL2 isn't working.

Tip

[1] Linux users should add renamed dll to overrides:

WINEDLLOVERRIDES=dxgi=n,b %COMMAND%

Important:

Please don't rename the ini file, it should stay as OptiScaler.ini.

Note:

OptiScaler supports these filenames:

1. dxgi.dll
2. winmm.dll
3. dbghelp.dll (nightly only)
4. version.dll
5. wininet.dll
6. winhttp.dll
7. OptiScaler.asi (with an ASI loader)
