It seems like they’re struggling / battling with the OS level APIs (Windows flavors and OS X).
Part of me wishes they’d do what FabFilter and Waves have done, which is to abandon the OS level graphics calls (mostly) and roll-their-own inside of a pure graphic framework (that’s cross-platform) like OpenGL.
Then, we’d get super responsive video game style performance for the Cubase UI and it would reduce the load on the main CPU, as a bonus.
They’d have to invent a lot of code, but I suspect they’d have better control over it than they appear to have now. And it seems like it would be more cross-platform port-able.
I feel like the Cubase UI shouldn’t have to slow down even when the ASIO Meter is pegged. Video cards are large enough to hold many monitors worth of “textures” which in this case would be Cubase UI elements, not underground mazes and planet scapes.
Anyway, it would probably solve all these font / text issues, too.
