TEKKEN 8 has broken visuals on certain stages (epilepsy inducing) with FSR4

[nikpikjoe]

Game name and version:

TEKKEN 8 (Steam)

Mods and mod versions used

Optiscaler 0.7.9 + Fakenvapi 1.3.4

GPU

RX 9070 XT

OS

Linux

Used automated or manual install?

• Automated
• Manual

If on AMD/Intel and Automated, used DLSS inputs?

• Yes
• No
• This is actually not an option on the Linux automated install. The .ini file says DLSS inputs are set to auto.

I tried DLSS Quality, Balanced and Performance modes at 3840x2160 display resolution. The issue persists across all options.

Did you check the Wiki and Compatibility List?

• Yes
• No

Please describe the issue and steps to reproduce it

The stage DESCENT INTO SUBCONSCIOUS - which is prominent in both online gameplay and in the story mode - shows severe graphical artifacts on using Optiscaler FSR4 on the second floor. This can be reproduced by going to training mode, choosing the stage, and selecting the restart position as below:

On initial load, the stage seems fine, however, as soon as any of the windows on the sides of the stage come into view, the entire screen flashes bright white to black rapidly and makes the game unplayable. Please see the video at the link below:

Troubleshooting attempts

Selecting the option Non-linear sRGB Input reduces the flickering, but it comes back within a minute or so, but instead of the whole screen flashing, the artifact changes to huge black squares appearing and blocking the view. Selecting the option Non-linear PQ Input gets rid of the issue, but corrupts the colours on screen (the flames on the candles turn black instead of white, characters get coloured differently, etc.). Neither option fixes the issue. The issue does not persist on choosing FSR 2.x variants in the dropdown menu.

I have attached

• OptiScaler.log (set LogLevel=0 and LogToFile=true in OptiScaler.ini, zip it if too big)

OptiScaler.zip

• Screenshot of game folder (where you placed Opti)

• Screenshot of Opti overlay in-game (opens with shortcut, default Insert)

Hi,

Log you have provided have no use, all init parts of the log is missing.

1. Could you provide whole log, maybe from a shorter play sessions?
2. Could you send a screenshot from this part of the menu:
   
   
3. Does this happens with older FSR4 versions?

[nikpikjoe]

Hi,

1. Sure, let me try to upload the log again.

OptiScaler.log

3. Yes, I've noticed this issue across 4.0.0, 4.0.1 and 4.0.2 - just didn't manage to report it earlier.

[nikpikjoe]

Some other things to note: outside of this scenario, FSR4 seems to work perfectly fine in this game without any issues. So, this is the only remaining problem. However, since the stage is unavoidable, often randomly chosen in online multiplayer and featured in several mandatory sections in the single player campaign, it breaks the whole experience. I am not sure if this issue also happens on Windows.

I'm curious, can the 9070XT run Tekken 8 at native 4K and a stable 60fps? (This game is locked to 60fps)

Wonder if this is an issue caused by spoofing. Hope the game doesn't have some kind of anticheat.

Could you try the attached version of OptiPatcher?

OptiPatcher_Tekken8.zip

• Create a plugins folder where Opti is installed and put OptiPatcher.asi in this folder.
• Enable ASI loading from OptiScaler.ini

LoadAsiPlugins=true

If successful, Opti Overlay should have a (OP) in the title and Spoof: Off

[nikpikjoe]

Hi, I tried the OptiPatcher attachment as you said. Same behaviour. Game doesn't have any anticheat to worry about, thankfully.

[TheRazerMD]

On the bright side, my DLSS patch works as expected. On the other hand, seems like spoofing isn't the issue afterall. Probably either a game or FSR4 specific issue.

[TheRazerMD]

Maybe try setting these commands from my other comment, but Opti should be automatically applying them already since the EXE name is standard UE.

#655 (comment)

[nikpikjoe]

I went to change the .ini file but those options were already set as default.

[TheRazerMD]

Unfortunately, it seems very game specific, might possibly be an internal FSR4 issue even.

[nikpikjoe]

Yeah, considering that all other UE5 games that I've tried work just fine, I'll chalk it up to a game specific issue. In that case, the compatibility wiki should be updated until this can be worked around. Right now, it says the game supports FSR4 just fine, it probably shouldn't say that.

[TheRazerMD]

Yeah, added the note to Tekken 8 entry. Hopefully this gets solved in the future, but we shall see.
