Placeholder texture or struggling hardware?

Was playing yesterday and noticed for the briefest, barely noticeable amount of time a tiny word ‘zap’ pop up in place of a shock/lightning effect.

I found it kinda cute actually, but it made me wonder whether it’s the hardware struggling to render a complex scene, or whether there’s a texture with a placeholder word instead of a graphic.

Playing on XBOX and in terms of smoothness it’s been generally fine.

Anyone else noticed this? It made me chuckle, like something out of a 60s Batman episode.

I’ve never seen that, it would’ve cracked me up!
