Enemies frequently slow down and speed up suddenly

[Graphcalibur]

Basically the title. Enemies seem to change speed often, going from normal speed to slower than back to normal again.

Slow down is most noticeable when the enemies have finished spawning and the "Next Wave" countdown begins.

Could this be due to frame rate variance?

[Graphcalibur]

I didn't notice any frame rate drops, though the FPS counter only looks at the main clock. There might be a drop for the in-game/enemy clock.

Hmm, interesting. I'll see if I can replicate this.
