007 First Light - D3D12AgilitySDK Update

What is this

This is a small technical mod for 007 First Light that updates the game's bundled D3D12 Agility SDK runtime to version 1. 619. 5. & No exe replacing required since the game is already using an earlier build of v1. 619

The goal is to improve the game’s DirectX 12 runtime behavior and potentially reduce stuttering / improve performance and framepacing.

What does it change?

• D3D12\D3D12Core.dll — updated to Agility SDK 1. 619. 5

Installation

1. Back up your original D3D12 folder (Don't forget this step)

2. Extract the contents of the mod archive into your Retail/D3D12 Folder

3. Replace the existing files when prompted.

4. Launch the game normally through Steam.

Performance

This mod is focused on improving overall performance, frame pacing, stuttering, and memory efficiency by updating the game's D3D12 runtime.

A newer D3D12 Agility SDK can potentially improve how the game handles its workload and manages resources, which may translate into:

Improved frame pacing — more consistent frame times and fewer noticeable spikes

Reduced stuttering — less hitching during gameplay and traversal

Better 1% lows — fewer severe drops during demanding scenes

Improved memory efficiency — potentially reducing unnecessary memory overhead and pressure

More consistent performance — better utilization of available hardware and fewer fluctuations in performance

Results can vary depending on your hardware, drivers, and settings.

Requirements

•  Windows 10 version 1909 or newer / Windows 11

•  DirectX 12-compatible GPU

•  Up-to-date graphics drivers recommended

Uninstallation

Restore your original D3D12 folder.

Alternatively, Steam's Verify Integrity of Game Files function can be used to restore the original game files.
