Published by the Fallout76 NX plugin (Fallout76_DLSSFrameGen.dll) through xScal's plugin callback ABI. If the plugin is missing or rejected, these names do not exist. Setters return false when the feature cannot be enabled in the active renderer session.
Enable DLSS frame generation
__SFCodeObj.call("Engine.EnableDLSSFrameGen"):BooleanNo arguments.
BooleanEnables it in an active NVIDIA session. If DLSS is the saved provider but the renderer started with frame generation off, saves the request for the next renderer restart.
Disable DLSS frame generation
__SFCodeObj.call("Engine.DisableDLSSFrameGen"):BooleanNo arguments.
BooleanDisables the active or saved request without changing FSR.
Enable FSR frame generation
__SFCodeObj.call("Engine.EnableFSRFrameGen"):BooleanNo arguments.
BooleanEnables it in an active FSR session. If FSR is the saved provider but the renderer started with frame generation off, saves the request for the next renderer restart.
Disable FSR frame generation
__SFCodeObj.call("Engine.DisableFSRFrameGen"):BooleanNo arguments.
BooleanDisables the active or saved request without changing DLSS.
Save Reflex On
__SFCodeObj.call("Engine.EnableReflex"):BooleanNo arguments.
BooleanAccepted when the active Streamline session has Reflex and PCL support.
Save Reflex Off
__SFCodeObj.call("Engine.DisableReflex"):BooleanNo arguments.
BooleanAccepted before renderer initialization too.
Providers the active renderer supports
__SFCodeObj.call("Engine.AvailableUpscalers"):StringNo arguments.
String (JSON)| Field | Type | Description |
|---|---|---|
DLSS | Boolean | |
FSR | Boolean |
Sample result
{"DLSS":true,"FSR":false}Requested frame-generation backend and applied Reflex mode
__SFCodeObj.call("Engine.GetUpscalerState"):StringNo arguments.
String (JSON)| Field | Type | Description |
|---|---|---|
DLSS | Boolean | |
FSR | Boolean | |
Reflex | Boolean |
Sample result
{"DLSS":false,"FSR":true,"Reflex":true}A provider stays false until it owns the renderer session, even when it was enabled for the next restart.
Save the frame-generation backend for the next session
__SFCodeObj.call("Engine.SetFramegenProvider", provider:String):Boolean| Name | Type | Description |
|---|---|---|
provider | String | One of DLSS, FSR, Off. |
BooleanExample
var available:Object = JSON.parse(__SFCodeObj.call("Engine.AvailableUpscalers"));
if (available.FSR) {
__SFCodeObj.call("Engine.SetFramegenProvider", "FSR");
