XeFG Testing and Compatibility List

[TheRazerMD]

OptiScaler v0.9 Test Build is now up on our Discord server

• Check either announcements or opti-test-builds

You can post your experience and findings here regarding different tested games.

Expect issues, but please report them with logs included

• To generate an Optiscaler.log file, please set LogLevel=0 and LogToFile=true in Optiscaler.ini then upload the log file here.
  If the log file is too big, please zip it and then upload.

Changes

• XeFG (+ XeLL) for even faker frames, with OptiFG (upscaler inputs) as well as DLSSG inputs.

Caution

• XeFG doesn't work in exclusive fullscreen! Make sure you are using borderless window.
• XeFG doesn't support Vulkan!
• Easiest way to verify XeFG is working:
  • Debug view which shows pink vertical lines when it's working
  • Along with the FPS jump, the frametimes will be doubled/thicker (but should be flat) - it's Intel's own Flip Metering equivalent
• Due to how XeFG works, you might need to activate XeFG once and then restart the game for all settings to apply.
• For Unreal Engine games, when trying to use Upscaler inputs with DLSS, please disable dilated motion vectors (same step as for enabling OutputScaling)
  • Edit game's Engine.ini and add

[SystemSettings]
r.NGX.DLSS.DilateMotionVectors=0  

• if the Engine.ini doesn't exist, you'll have to create it and possibly make it Read-Only if the game deletes it on boot

• Separation of FG Sources (inputs) and FG Outputs, you need to select both

  • This made the framework a lot more modular for supporting different kinds of FGs
  • In previous builds, OptiFG was always internally Upscaler -> FSR FG, now it also support Upscaler -> XeFG (OptiFG/Upscaler is without the HUDless resource, but unlike FSR FG, XeFG does interpolate the HUD more or less well)
  • To achieve previous Nukem FG, selecting Nukem's DLSSG will automatically switch the output to FSR-FG via Nukem's as that's the only option (Nukem's DLSSG -> FSR-FG via Nukem's)
  • DLSSG via Streamline inputs (only DX12 and Streamline 2+ games), requires you to enable DLSS-FG in the game and then enable FG in Opti's overlay - this is our own equivalent of Nukem's mod which is a lot more versatile, albeit less compatible atm as noted

• fakenvapi included as fakenvapi.dll, add it on Nvidia as well, best to remove old nvapi64.dll

• Option to draw UI over fake frames in some games with DLSSG inputs when using FSR FG

We are also working on OptiPatcher that unlocks DLSS/DLSS-FG inputs without spoofing in supported games - but that requires manual patching, hence only listed games are supported.

Great to see the compatibility list, copying over my 2 tested games from before to have it documented

Both Cyberpunk and Oblivion Remastered work when routing DLSSFG inputs to XeFG. Minor graphical bug on Oblivion, where 5 pixels~ of the border can aliase (also present in the native ingame FSR3FG implementation). Cyberpunk worked extremely well with excellent framepacing. Visually, Optiscaler produced better UI/HUD texture stability with fewer issues compared to dragging & dropping the updated .dll from XeSS (for Cyberpunk)

"Display generated frames" also worked on Oblivion remastered with XeFG. It did crash a few times but i eventually got it to work. RTSS was not in use. So it can eventually engage if anyone wanted to use OBS to capture gen frames only for pixel peeping. Overall, very impressed with XeFG & XeLL and a usual thanks to the Optiscaler team for their work

[TheRazerMD]

From the last few days of testing out XeFG, all these games seem to work:

• Robocop Unfinished Business
• Witchfire
• Ghostrunner 2
• Remnant 2
• The Alters
• Ready or Not
• Roadcraft - also works, but requires a newer version due to some Reflex shenanigans of theirs

All these were tested both with DLSSG via Streamline -> XeFG and Upscaler -> XeFG.
Upscaler -> XeFG required UE Engine commands, but after that worked fine too. XeFG more or less managed to deal with the HUD. HUDfix cleaned up the crosshair and similar if needed (can't vouch for longterm stability).

• Lies of P - Upscaler -> XeFG (no Streamline here)

[DWLX556]

For FF7rb, xefg doesn't seem to work, as there's no change in frame rate, while FSR FG functions normally.

Hitman 3 does not work
Dying light 2 does not work

[TheRazerMD]

@DWLX556 FF7 Rebirth was fixed in a newer build which wasn't "officially" shared and pinned yet. It was yet another Squenix moment with them.

@QwertyCrazy Hitman 3 has issues with DLSSG inputs, but OptiFG/Upscaler works for me.
Don't know for DL2, but it not working is about what you'd expect from that game. You can also try Upscaler -> XeFG to see if that works.

Ghost of Tsushima can run with DLSSG, but it requires Fakenvapi and is prone to crashes.

I also have OptiFG-XeFG working in hitman 3, but XeLL doesn't work, and hudfix doesn't work either.

DLSS Streamline + XeFG working great in Clair obscur Expedition 33. Looking forward to more improvements

[kisekinopureya]

Upscaler -> XeFG works on Stalker 2 with OptiPatcher, but XeFG only works if FSR or DLSS is set to Native. Also, for some reason, after installing OptiPatcher, DLSS and Reflex appear in the settings, but DLSS FG is missing.

@kisekinopureya you've probably ignored this part, would explain why it only works on Native.

• For Unreal Engine games, when trying to use Upscaler inputs with DLSS, please disable dilated motion vectors (same step as for enabling OutputScaling)
  • Edit game's Engine.ini and add

[SystemSettings]
r.NGX.DLSS.DilateMotionVectors=0  

Also not sure why OptiPatcher would even trigger on Stalker 2 since it isn't a supported exe. But if I got ahold of the exe, I could probably patch both DLSS and DLSS-FG to unlock.

[kisekinopureya]

@TheRazerMD There was no Engine.ini in the config folder, so I added that setting to GameUserSettings.ini and created the Engine.ini file. Some people also say that the Steam version does not use Engine.ini reference 1 reference 2

OptiPatcher is triggering because i added it

[TheRazerMD]

@kisekinopureya ahhh, so they're one of those devs. You'll have to create the Engine.ini and make it read-only probably. Technically you can disable the Dilated MV under Advanced Init Flags in Opti overlay, but that'll most likely end up in weird ghosting.
Also good job adding support, but Streamline/DLSSG have different checks, hence only DLSS being exposed.
