Half-Life 2 on Xbox.

The performance is alright, if you played the game before the Orange Box update you'll notice how the Xbox version did have stand out improvements. Notably the lack of a loading stutter. HL2 and other Source games famously had no precaching for sound files so often times when they were first being loaded into memory from HDD they would stutter until fully loaded. It was very bad but Xbox didn't have this problem. The stock audio experience is also tremendous on Xbox. Very good 3D soundscapes even present over stereo sound. PC at the time would require EAX hardware which is its own conundrum these days.

Framerate isn't amazing, but it isn't particularly bad for this generation. I believe it could have ran better but it isn't terrible.
