I upgraded my PC last year and it can definetly handle AoE4 - and i guess AoM:Re too - on highest settings. The only thing that bothers me a bit; if i knew back then that AoM:Re will have raytracing i might have chosen an RTX Gpu 😅 Oh well, whatever.
No. It's true that game is built in Aoe 3 de engine. But still models are better and there are more details in the game than aoe 3 De. It Even supports ray tracing which is something modern AAA games have. So you can guess. Not just that, the system requirements published on steam are totally similar to aoe 4. Retold has better visuals than aoe 3 de. The game trailer and released gameplay is enough proof of that.
