for real this is my biggest pet peeve with modern games. shitty shadow cascading. I was playing elden ring and that game has some of of the worst, low res blobby most distracting shadows ive ever seen.
Shadows are INCREDIBLY expensive because their cost rises in logarithm instead of linear fashion. With each new light you have to recalculate whole scene another time and take into account existing shadows. So by 6 light source casting shadows you are looking at power of 6. Only real way to deal with that problem is either bake them aka no dynamic shadows/lights or raytracing which skips whole issue as nothing is recalculated with each new light source and shadows are just lack of light rays thought it creates its own power hungry set of issues.
You can have 1000s of dynamic lights without shadows but you can only have like 6-7 lights with shadows IN MODERN GAMES. So usually you have your sun casting shadows, few nearest lights casting shadows and character torch/light casting shadow and that's it. And even those have very aggressive limits.
So only raytracing can help here and by that i mean path tracing rather than hybrid we use today.
