[Apex Neural Rendering](https://apexcompute.com/neural-rendering) by [Apex Compute](https://apexcompute.com).

- **ANR FG** : frame generation. In beta.
- **ANR SR** : super resolution (upscaling). Beta soon.
- **ANR RR** : ray reconstruction (denoising for ray tracing). Beta soon.
- **Source code** : coming soon.

1. Download a package from [Releases](https://github.com/apex-compute/ANR/releases) :
  - `anr-fg-full` : for games without OptiScaler.
  - `anr-fg-addon` : for games that already use[OptiScaler](https://github.com/optiscaler/OptiScaler) .
2. Close the game, extract the package and run the installer with the folder of the game's `.exe` :
  - Windows: `install.cmd`
  - 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
3. Windows: 
4. 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.

- NVIDIA GeForce RTX 20, 30, 40 and 50 series, and GTX 16 series
- AMD Radeon RX 5000, 6000, 7000 and 9000 series, and Steam Deck
- Intel Arc A and B series

On Windows 10 and 11, and on Linux and SteamOS with Proton.

Please post them as [issues](https://github.com/apex-compute/ANR/issues/new/choose):

- **Performance results** : run the test kit from the release and attach its result file.
- **Problems** : the game, GPU and driver, operating system, settings and what you saw, with the newest`nr_fg-*.log` from under the game's`OptiScaler/custom/Apex Neural Rendering FG` folder.

OptiScaler is GPL-3.0; its source for each release is attached to the release.
