GT64 simply doesn't have what it takes in the gameplay department. Once you have driven each course once, it gets boring faster than staring into a tub of lard. It doesn't help that GT64's Championship Mode forces you to qualify for each race by driving a full three laps on the often over-long tracks in an attempt to prolong the play experience. Sorry, but racing three tracks alone on the same track over and over again before racing the same tracks for another three laps against a gang of lacking AI drones is not our idea of fun. No steering wheel support, either.
Some games have amazing music, causing the graphics engine to slow down a little.
Other games draw tons of cars and track detail on screen which causes the engine to slow down. GT64 has none of these features. Heck, it doesn't even have music during gameplay. We're still not sure why this game has such abysmal framerates, but trust us when we're saying that MRC runs a whole lot faster. To make things worse, GT64 is blurry and ridden with tons of pop-up and sloppily designed textures that don't quite line up.
