Day of Defeat 1.3 is a great game, and I get 60FPS on my Geforce 5200FX. When I play Day of Defeat: Source, I actually get 40FPS most of the time, and the game still looks great! Sure I cant put on AA or AF or HDR, but compared to BF2, which on my card, with ALL settings on low, the game looks like crap and runs like it, but not with Source. Even in a 32 player match, there is little slowdown! So if you have any card older than the Geforce 6 series, games that use the Source engine and the Half-Life engine are worth looking into.
