this a collection of files and a guide on how to enable FrameGen on non-40 series cards

this mod contains a file from PureDark Patreon that enables DLSS FG which is disabled by the developers

Installation:

first: launch the game normally and set those Graphics settings as follows: DLSS: anything except off. Nividia Reflex: on. framerate: variable. Vertical Synchronization: on

second:  Download and unpack both .dll files from this mod to your Dragons Dogma 2 folder

third: download Nukem's dlssg-to-fsr3-0.90 (Universal) mod and within that folder you'll find multiple folders. the one we need is dll_version. open that folder and copy: dlssg_to_fsr3_amd_is_better.dll and version.dll to your Dragons Dogma 2 folder.

Now, in your Dragons Dogma 2 Folder, find the file named shader.cache2 and delete it. (you have to do this step Each time you want to launch the game)
(Optional)added a batch file that automatically deletes the shader.cache2 each time you launch the game. treat it as the game launcher
Tip!!! Deleting shader.cache2 is not necessary if you are using ReFramework. Check Compatibility.

We're almost done! All you have to do now is make sure NVIDIA Overlay or Msi Afterburner is turned off, if not the game will crash on launch. if the game still crashes on launch, check if you have any performance monitor overlay turned on and try to turn it off

lastly in the Windows search bar Search for graphics settings, once you're there, depending on the Windows version you have you'll see an option Named  Hardware-accelerated GPU scheduling, turn it on. if it's not there there should be some blue text called something like "Change default Graphics settings" Within it you will find the Hardware-accelerated GPU scheduling just turn it on.

Done.

now after launching you will notice the UI stuttering, well that's the only downside, But You can disable it by pressing the End Key which will stop both The FG and the stuttering.

for non-Nvidia cards try downloading the first file from dlssg-to-fsr3 and only copy the DisableNvidiaSignatureChecks.reg to the game folder and run it.
since I only have a Nvidia card, I don't know if this will work but if anyone knows or has tried it please let me know to update the description 

Uninstallation:

delete: nvngx_dlss.dll, sl.interposer.dll, dlssg_to_fsr3_amd_is_better.dll, and version.dll located in the game's folder
then download the optional backup file on the files tap and place it in the same folder. done

Compatibility 
If you have ReFramework Installed, all you have to do is launch the game once with ReFramework installed, it will then create a folder Named _storage_
 in the game's folder. now cut the file named dlssg_to_fsr3_amd_is_better.dll to that folder and any issues should be fixed.
You won't have to delete the shader.cache2 if you have ReFramework installed
