Yeah, that's a pretty common problem with games from the late 90s - early 2000s. Games either couldn't run at high resolutions at all, or they stretched like that, which happened in the first Max Payne, by the way, or the picture lost its field of view, which happened in the first Half-life before the 25th anniversary update and in the first Deus Ex.
