Summary	07568: hyprdriv: Game randomly soft freezes
Description	Video will stop but music will keep playing. It's possible to soft reset (default F3).
Steps To Reproduce	Run the game.
Additional Information	As of 9/5/2021, I can confirm the game does not lock up when running without the DRC. Another issue possibly related to this would be the video would skip every few seconds. During that time, the video temporarily stops rendering for 10-12 frames skipping around 5-6 rendered frames. This, strangely, happens when running without the DRC. This doesn't happen on NFL Blitz despite running on the same hardware.

At the same time, this isn't looking to be an easy fix. With this issue and the frame issue mentioned, this game needs a good pcb recording. I can't help but think Hyperdrive was poorly optimized because of this as well. If anyone can find abnormalities in the game code, that would be excellent.
