I played Mars: War Logs before, so I knew what awaits me in this game :)
I have to admit, it is good, I mean really good. The story is very enjoyable, at least for me it was.
Yes, there are many backtracking between different locations, here and there, especially with sidequests, but you know what? Thats why you know the places better and better.
I have made myself a build of two specializations: technomancer (magic) and warrior (attack with stick). It did work for me quite ok.
I only did have two crashed, but that because I ALT+TABed out of the game and when you leave it in this mode it will hang after 15 Minutes or so. So don't do that. Save the progress and exit the game.
I played on: Ryzen 5 1600 with Radeon RX VEGA 7 integrated GPU, 32 GB DDR 3200 MHz RAM, 1 TB SSD, Windows 10 Home 64-bit 21H2. Low settings, 1080p, I've got about 27-45 fps, depending on the scene in the game.
So, if you have a better dedicated GPU, it should work without bigger problems.
