Performance Update - Smooth Streaming is Here

Hey everyone!

I've been heads-down for the past two months making some serious improvements, and wanted to share what's new as we gear up for Early Access.

🎮New Features & Polish

There are a ton of changes across Career Mode, the file browser, Measure Master practice analysis, Set-list management, Stats screens, and more. New options, redesigned layouts, quality-of-life improvements throughout. I have it all documented and you'll discover these as you play - but that's not what I want to focus on here.

⚡Performance Overhaul - Finally, Smooth Streaming!

This is where my time went. Almost all of it. I had to stop playing the game entirely and spend two months doing nothing but profiling, testing, and optimizing frame-by-frame. Measuring milliseconds. Tracking down micro-stutters. Writing custom code when standard solutions weren't precise enough. It was painstaking, tedious work - but absolutely necessary. Streaming and recording gameplay needs to be smooth. Frame drops aren't acceptable.

What I tackled:

  • GPU rendering is now on by default and fully optimized

  • Eliminated micro-stutters through precise frame timing at the sub-millisecond level

  • Added Metal acceleration and triple buffering with proper GPU synchronization (Mac), optimized OpenGL buffer management (Windows)

  • Wrote custom C++ modules for precision timing that standard libraries couldn't match

  • Added shader pre-warming so notes don't hitch when they first appear

The result: Buttery smooth 60fps gameplay, even while running OBS and LUNA/UAD Apollo.

🚀What's Next

I'm in the final stretch before Early Access. This update represents a huge step forward in stability and polish. Keep the feedback coming - it directly shapes what I prioritize.

Thanks for being part of this journey.

More news soon!

How it works The beta branch always runs either the same build as the default version or a newer one that's being tested. Opting in is low-commitment — you can switch back to the default version anytime. When beta is ahead, you're previewing the next build before it goes live; w…
