eli5 Why do old pc games that look good run better than new PC games that look bad

443 views

For example, I have a decent non-gaming laptop I can’t figure out how I can run say battlefield 4 or titanfall 2 or even GTA v which looks great at 50-60fps pretty consistently however I can’t run say outer wilds or apex or cod at minimum with the resolution set so low I can barely see but only get 20-25fps it just doesn’t make sense pleaaase help me understand thanks so much guys!

Performance is all about bottlenecks.

E.g. If you need to load 1 Gb of textures into memory, but only have 500 mb of memory, you’re going to see performance problems as textures are moved in and out of memory.

An old game is probably expecting lower bottlenecks. If you avoid the bottleneck, you avoid the performance problems.
