To begin with my PC Specs aren't the best out there, a Ryzen 5 1600 CPU from 2017, 16gb of 2400mhz RAM. and a RX6600 with just 8gb. Game on SSD, the cheap sata type. PCI 3.0 Motherboard. < Yes, im very CPU limited and it is the biggest bottleneck for the card I've paired it with. So you can see with what type of hardware I'm currently running the game.

AFOP.exe

The main executable, right click on it > properties > check Disable Fullscreen Optimizations. In-game select Fullscreen mode.

This is required for the game to load faster and compile shaders more efficiently.

Download the package from here:
https://www.nuget.org/packages/Microsoft.Direct3D.DirectStorage/1.2.4

You might have to rename the file extension to .rar to extract it.
Install the update heading to native/bin/x64 > copy the new dstorage.dll and dstoragecore.dll to AFOP game folder.


The last released upscaling solution from Intel.

Download the package from here:
https://github.com/intel/xess/releases/tag/v2.0.1

Install the update heading to XeSS_SDK/bin > copy the new libxess.dll to your main AFOP game folder. Replace the file.

For Windows paging file or virtual memory I've set it fully managed by Windows itself, on automatic. Leave it auto do not mess with that. It should be smart on how it handles the paging file a.k.a. virtual memory.

Head to the graphic config file

Located at My Games/AFOP/. Here open: graphic settings.cfg and look for these values, set them as shown here:

vignette = false,
presentInterval = 0,
reduceLatency = false,

Explanation:
Vignette and frame generation do not get along too well, so it is best to disable it. PresentInterval is VSync, it has to be disabled for the less possible latency. And speaking about latency.... Ironically as it sounds but reduceLatency has to be disabled, otherwise it'll bring more stutters. So replicate these settings. If you need or want a frame limiter for extra stability, I suggest to cap the game with RTSS (Riva Tuner). This should help with the frametime and frame-pacing issues. It will also cap the frame generation output aswell.

In the same config file look for ["streamer dedicated budget"] = xxxx,

You see I wrote "xxxx" here you should try your total GPU VRAM, in my case it is 8gb so it goes in mb, meaning I put ["streamer dedicated budget"] = 8192, < this is an example.

8GB = 8192
6GB = 6144
4GB = 4096
2GB = 2048 (R.I.P. if you have a 2gb card)

For more just multiply your VRAM in GB x1024.

Save the file. Do a backup first if you want.

If you are on AMD:

DISABLE - DO NOT USE ANTI-LAG NOR AFMF (AMD Fluid Motion Frames).

If you are on NVIDIA:

I can't speak about Reflex but try with or without see what works best, and set your Shader Cache Size to 10gb via the Nvidia control panel.

Enable FSR 3 Frame Generation in-game or DLSS (if you are a RTX40 user), I personally do not use v-sync, a manual frame-cap is always better, both in terms of latency and CPU/GPU usage.

With these settings I am able to run the game at 1080p with FG enabled around 90 to 110fps and it goes actually very smooth. Hope it works for you too.

Always keep in mind, despite FSR3 being an open source technology, it'll always work best in AMD cards, as so does DLSS which will always work best in RTX4000 cards (because it is exclusive to 40 serise only) RTX20/30 cards should handle FSR 3 FG "alright", but not perfect. However 10series users will likely see problems. So this is a gray-zone unfortunately, cant have everything.

This is all trial and error.
