But I daresay we may actually be approaching the first real Synthesia 11 dev preview.
If never fails.
I should know better than to give predictions. Hence my usual policy of only mentioning release dates a day or two ahead of time.
The new stuff seemed reasonably efficient on my tiny super-computer of a development PC. Trying it on some tablets... I learned that was not the case. On the worst Android device I could find, a sheet music page-turn freezes the app for about a quarter second every time (followed by an out-of-memory crash a few pages later).
After some investigation, there was a funny conclusion: the new drawing code is actually quite fast, even surprisingly so. It's some infrastructural stuff that is causing the hiccups: uploading that large of a texture to the GPU all at once, etc.
Anyway, far from this being a setback, it means I get to work on an interesting optimization problem! This is one of my favorite areas that I usually have woefully few opportunities to exercise. I've already squeezed about 5x(!) the performance out of the GPU upload procedure. The already-fast sheet drawing code is also 2.5x faster now, too.
And, so this doesn't just sound like a feature-less detour -- making things "fast enough to not feel broken" probably isn't especially exciting for users -- already the big gains have required adding some new tech (arbitrary shaders!) that will become phenomenally useful in the short and long term. I've wanted an excuse to add them for years and this was a great one.
In any event, this road is a little longer yet. It doesn't stop until the worst platform can change sheet pages (zoomed as large as possible) without dropping a single frame. I've still got half a dozen tricks up my sleeve and I can't wait to try them.
So, the first real preview is still close. Just not quite as close, hehe.
