1
00:00:00,000 --> 00:00:05,427
In Project Heartbeat mere milliseconds can mean the difference between a

2
00:00:05,527 --> 00:00:09,957
record breaking run or an absolute failure. As a result, we

3
00:00:10,057 --> 00:00:14,793
are in an everlasting quest to lower latency and increase input

4
00:00:14,893 --> 00:00:20,551
consistency. With Project Heartbeat 2's new game engine, we've replaced the

5
00:00:20,651 --> 00:00:25,388
input system and developed cutting-edge rhythm game technology.

6
00:00:25,466 --> 00:00:28,392
The game's logic is now completely dettached

7
00:00:28,492 --> 00:00:31,419
from the framerate, through the new advanced

8
00:00:31,519 --> 00:00:35,614
tickless system developed specifically for Project Heartbeat.

9
00:00:38,700 --> 00:00:44,115
In previous versions of Project Heartbeat, your input used to only get checked

10
00:00:44,215 --> 00:00:48,712
once at the start of each frame. Any button presses you did after

11
00:00:48,812 --> 00:00:53,167
that got snapped to the start of the next frame. With the tight

12
00:00:53,267 --> 00:00:59,249
and fast gameplay of Project Heartbeat, this could mean the difference between getting

13
00:00:59,349 --> 00:01:04,057
a FINE rating and failing a perfect run. With the new subtick system

14
00:01:04,157 --> 00:01:09,361
this no longer matters, the game now knows when you've pressed every single

15
00:01:09,461 --> 00:01:14,382
note and is able to precisely evaluate it. Effectively acting as if you

16
00:01:14,482 --> 00:01:16,928
were running an infinite frame rate.
