I mean...your CPU can run Red Dead Redemption 2...
Yeah, but BG3 isn't finished. A game can kill any computer if unoptimised enough. While I didn't play RDR2 specs are about more then graphics. Most of AAA systems tend to be rather basic - add a lot of systems and simulations that needs to be run, characters to be trackets etc. and especially processor power can be in great demand. I am sure requirements will come down overtime, but with over two weeks before EA release even Larian might not quite know how high exactly will the EA requirements be.
