Its definitely odd reading some of the user reviews. Most of the specs I have seen people post fall within the minimum to recommended specs. Only one negative review I read posted their stats that clearly only met the minimum for low settings, an old Ryzen Zen 2 and Radeon 5000, that clearly should have known better. I'm betting if people at least selected DX11 instead of 12 (if it's an option in the menu), that might help in the mean time.

DX12 is also coming out with updates that will make it easier for the cpu and gpu to communicate and share a pool of VRAM, which should improve things greatly once devs can utilize it. Some engines are also adding the ability for Devs to pre-compile like in Unreal 5. Right now this stuff is likely to be encountered in other games released this year with the growing pains of new tech.
