Unfortunately that’s not how it works. This is coming from someone who studied computer hardware and software in university.

Cache sizes are a trade off. Small cache means quick access speeds but higher chance of a cache miss. Larger caches have a lower access speed but a lower chance for a cache miss.

This is why we have different levels of cache on a computer actually. It allows us to harness the benefits of the different sizes of caches without impacting the speed as much. With multiple layers we can have small caches that are super fast and then larger caches that are slower and so and so forth. This way we can have both speed and size.

Generally there’s a reverse relationship between size and speed. A 8gb cache would also be super slow thus defeating the purpose of the cache. If it were so easy every cpu would have a huge cache

I just wanted to comment to say that I find the game just as buggy as you say. I do think that some people are more sensitive than others. I’m playing couch coop and my gaming partner doesn’t notice any of the bugs until I call them out for him. Unless they are game breaking. Within 11 hours of play I have encountered 3 bugs that warranted a game restarts and countless other bugs that ranged from minor to frustrating.

This is typical larian though. Divinity 1 + 2 were the same for me. If anything this game is even buggier.
