I bought a used 6700XT a few years ago, but — at least according to the official system requirements — my CPU would’ve been underpowered.
According to YouTube it might’ve been fine, although of course the tutorial environment is quite small:
The game environments are quite detailed. Just like nearly all modern games the lack of saving is occasionally driving me crazy. In (classic) Tomb Raider you save before attempting a dangerous jump. The autosave system does something somewhat similar, but less convenient.
The game looks great and the atmosphere is good. Sneaking around is orders of magnitude more challenging than the puzzles at this point, but the good news is I like that sneaking around in e.g. Dishonored and the Tomb Raider 2013 trilogy.
