Animation Bug, Constant Single Frame Animation Flicker.

[Poptartsicles]

I've encountered an animation/character model bug, where the animation will constantly flash to a different animation for a single frame, then go back to normal again, and do this so fast that it looks like it's flickering. Freeze frames show the character model performs a different animation for a single frame, like changing facial expression, while standing in a slightly different position, then goes back to normal again. It's borderline seizure inducing at times. Interesting to note, the higher the frame rate, the more frequent this happens. It's almost not noticeable if I lock the framerate to 24fps, but with an unlocked fps it happens very rapidly, indicating it's happening every certain number of rendered frames. I recorded 2 video examples:

- I've already tried verifying game files on Steam.
- I've already tried updating to the latest Nvidia drivers.
- I've also tried reverting back to the older launch drivers.
- I've tried turning on and off and lowering and raising every graphical option.
- I've tried v-sync on and off. I've tried fullscreen, windowed, and borderless fullscreen.
- I've updated Windows 10 to the latest update.
- I've tried fully uninstalling and re-downloading the entire game.
- I've tried turning off all global Nvidia Control Panel settings back to default.
- I've tried the Arc GPU Beta (because I'm desperate).
- I've rebooted my PC after trying everything I've mentioned above.

I've run out of ideas.

I don't have an issue like this in any other game I play, including the first game which I actually just played for the first time a few weeks ago and beat just recently. I was really looking forward to Remnant 2, but this issue completely ruins the experience and genuinely hurts my eyes after a while.

I'm having the exact same issue but worse. The flickers I am getting or constant and insanely large, I had the same problem with Fortnite after some updates and never could fix it. I'm worried about it being 3060ti issue.

I actually just discovered the problem and the fix today, took A LOT of digging... It's got something to do with AMD CPU's it seems. I had to change the affinity of Remnant 2 in Task Manager so it would only use threads 0-11, turning off 12-23. Then the flickering just stopped.

Task Manager<Details< right click Remnant 2, check and uncheck CPU's until the flickering stops.

I'm guessing it's something to do with the infinity fabric that lets the 2 chiplets talk to each other, not playing well with Unreal Engine 5 on specific systems.

I found the solution here:

If your situation is like mine and it's the infinity fabric you may need to disable CPU 11-6 (or 0-5), which sadly means only 3 cores and 6 threads will be usable for the game, but the glitch should stop at least. It's not a great solution, that's for sure, and you'd need to manually re-apply the fix every time you boot up the game, unless you can get this solution working:

I couldn't get the permanent affinity thing to work, but maybe it'll work for you. Worth a shot.

I was going to come back the other day. For me I turn of core 1 and 2 and it fixed it. I am so happy that it was that simple!
