Major Shadow Flickering With SurfaceAppearance MeshParts

Hello, in my live game (not in studio) I have major shadow flickering with MeshParts that use SurfaceAppearance. Two videos are below.


The place file in question is: (1) [Testing] Samurai Combat - Roblox

The only reproduction steps, for me, are simply to join the game and let the shadows load in. They start flickering during playthrough.

The PC specs for the machine that this occurred on are:
OS: Windows 10
GPU: GTX 960 (GeForce driver v460.79)
CPU: i7-8700K

Build: 0.459.2.415937

It never stabilizes. Graphics quality set to Auto and internet download speed at the time was 200Mb/s

That made 0 sense and has nothing to do with this only happening on SurfaceAppearance mesh parts. I’m not running an FPS unlocker.

Thanks

I can’t reproduce this at your place at any graphics and FPS cap setting. Win10, Ryzen 3900X, GTX 1080 with 456.81

@ix_EcIipse Glitches appearing at different, common FPS ranges are indicative of terrible code implementation. Definitely not acceptable in this decade and surely a bug.

Thanks for confirming it’s not happening everywhere with your specs as well!

I narrowed it down, for myself at least so far, and when I join with automatic graphics the flickering happens even if I change them manually in game. However, if I join with manual graphics by default (both videos shown below) there is no flickering.

Hopefully this helps an engine developer look into this if possible.

What part of “no I’m not using an FPS unlocker” are you not understanding?

Unfortunately I don’t have my PC with me, meaning I can only use a phone, meaning I can’t play the game.
However, (this is probably going to sound really really dumb) in your thumbnail it shows the view area kind of odd.
That is probably incorrect to a scale of just stupidity.

If you turn off global shadows do they go away?

Have you tried making a different game, copying everything over, then does it still happen?

Try reinstalling Roblox, does anything change your FPS (Not just the FPS unlocker, but hardware, software, just things that may alter your FPS in general), try changing graphics on Roblox, try on other devices and internets, are any other games doing this, do you have anything in lighting that might be doing it, etc.
