Topic: 3D settings, frame rate and replay file size
Ever since upgrading my computer (it's now much faster than before) I had wondered why many of my newly-made replay files didn't look as smooth as the older ones. Sometimes they were downright twitchy, as if recorded with a very low frame rate. In some cases key frames - such as the exact moment the ball grabbed a coin or hit the floor - appeared to be lost. When replayed, this meant that the ball would miss the coin or that no 'bump' sound would be heard, respectively. Moreover, there was the floor vibration problem. All in all, I had many nice replays ruined by all of this.
I have now found that if I open the NVIDIA control panel and set the "Vertical sync" option to "Force off", all of the above problems disappear. Now that the frame rate is no longer tied to the refresh rate of my monitor (60Hz), Neverball says that I get between 200 and 650fps depending on the level and situation. Previously, the value was stuck at about 56fps. The game feels smoother, and, what's even more important, the replays are now finally as smooth as they should be. Those crazy floor vibrations are gone, too. Hooray!
One consequence of this, though, is that the replay file size has increased by a factor of 7-9. This doesn't cause any storage problems for me personally, but it's unclear how the Nevertable will handle it. I'll open a topic in the Nevertable forum for this. I don't suppose there's a way to tell Neverball to limit the maximum frame rate of a replay to a given value, say, 150fps?
