My 4090 usually sits at 10-16gb vram in some games at 4k max settings,  dlss quality, ofc the poorly optimized ones like steelrising can chew trough almost 20gb vram at full max settings and 4k dlss quality.

I've heard that sometimes games and apps will use up more VRAM (and regular RAM) than they need if it's available. Could that be the case here?
