ANR FG Beta, FG V.B15

Changes

• Windows (native D3D12 games): VRAM use no longer grows when the game re-creates frame generation, for example on a resolution change or with dynamic resolution (#11). The copies of game textures that ANR FG keeps are freed when frame generation is released and when the game stops using them, and a released frame generation instance is freed 5 seconds later. Before, each re-creation added several hundred MB at 4K until the GPU ran out of memory, the frame rate dropped to a few frames per second and the game could crash.
• nr_fg.ini no longer offers model_size = small: these packages have one model size.
• The logs name our GPU kernels by short codes instead of their source names.

Known limit: at 4K on an 8 GB GPU, a game that uses most of the VRAM itself can still go over the budget with frame generation on. If the frame rate drops sharply, lower the output resolution or the game's texture quality.

Packages

• anr-fg-V.B15-full.zip: for games without OptiScaler.
• anr-fg-V.B15-addon.zip: for games that already use OptiScaler.
• anr-fg-V.B15-kit-windows.zip, anr-fg-V.B15-kit-linux.tar.gz, anr-fg-V.B15-kit-macos.tar.gz: test kits (TESTERS.md inside).
• anr-fg-V.B15-full-optiscaler-source.zip: OptiScaler's source (GPL-3.0).

Install

1. Close the game, extract the package and run the installer with the folder of the game's .exe:
   • Windows: install.cmd (needs the Microsoft Visual C++ 2015-2022 Redistributable, x64)
   • Linux and Steam Deck (Proton): sh install.sh "<folder>", then set the game's launch options to the line it prints (WINEDLLOVERRIDES="dxgi=n,b" %command%, or winmm=n,b in Vulkan games)
2. In the game, turn on frame generation (the NVIDIA option where the game offers several).

To uninstall, run uninstall.cmd or sh uninstall.sh with the same folder.

Supported GPUs

NVIDIA GeForce RTX 20 and newer, GTX 16; AMD Radeon RX 5000 and newer, Steam Deck; Intel Arc A and B. Apple silicon (M1 and later). Windows 10 and 11, Linux and SteamOS with Proton, and macOS 26 or later.

Feedback

Post performance results (the test kit's result file) and problems as issues, with the newest nr_fg-*.log from the game's OptiScaler/custom/Apex Neural Rendering FG folder.
