Changeset 1621 for code/branches/hud

Timestamp:

Jun 23, 2008, 9:12:59 PM (16 years ago)

Author:

Message:

• rewrote the time measure in the main loop frame smoothing is gone for good and the fps display updates faster
• changed "render time ratio" to "tick time in ms" which represents the time necessary to tick() one frame that's saying a lot more to me
