The PSX came first but has the worst graphics of the bunch. Everything looks much better than the first game. However, it pales compared to the other versions. The DC version sports much better graphics, a higher resolution and much less fog and the PC version tops even that. On the Philly level, you can see clear across the stage, all the way back through Phillyside and the trains.
Graphics are great here, crisp, and a wonderful amount of detail.
The distance you can see might not meet that of the PC port, but it does well and all looks good here. Load Times Another simple choice. The PC port has minimal load times as expected, putting this atop the listing here. Well, not quite. You've got to give the dinosaur system credit in that regard.
