There's been a few references to this but I thought I'd put it into an explicit thread.
I've got higher expectations for Kazoo than I had for Kinsky as this is control point v2.0, so I'm being a harsher critic. With that said, the scrolling experience is disappointing.
I'm using my decent, integrated graphics, Windows desktop (Core2 Duo 6400 2.13GHz, 2GB RAM, SSD), and a 1920 * 1200 display, connected to a fast Windows server (Core i5 2500T, 2.3GHz, 8GB RAM, SSD OS, 4 * 2TB HDDs in RAID 1+0 for data) running Kazoo Server via wired gigabit ethernet connection, with just a single GS108E netgear switch inbetween. Windows performance index scores are 4.7 for desktop graphics performance for windows aero, and 4.1 for 3d business and gaming graphics. The system should be fine.
1. If I have Kazoo full screen and click the mouse wheel up or down a notch, it's fine. By the time I'm scrolling with the mouse wheel at 3 or 4 notches per second, Kazoo doesn't draw covers quickly enough to keep up. If I do this with a smaller window then performance is better but it's still easy to scroll quicker than Kazoo draws covers.
2. If I drag the blue scroller, the blue scroller itself moves very jerkily and with significant lag, even on a small window. Curiously, it seems to be much better when Kazoo is first opened, or after the window has been maximised and restored. But if the window height or width is changed by dragging with the mouse, scroller performance immediately becomes poor and stays poor.
3. Even when performance of the blue scroller itself is good (e.g. immediately after opening Kazoo), the animation of the covers is sufficiently slow that even when move the blue bar very slowly, the screen is permanently blank until I stop scrolling. Or if I move the blue bar a little slower, it may just have the rapidly scrolling (and so virtually illegible, see point 4) album name text, but no covers.
4. Finally, when scrolling with the mouse wheel (which is fine-grained enough scrolling that the screen doesn't go blank if I scroll slowly), the animation of the covers is still so coarse that it's hard for the eye to track. What you want to do, as a user, is scroll vertically while scanning with the eye horizontally, to locate an album by sight. Or just scroll through and admire your collection. As it stands, you have to scroll, then look across a row, scroll again, then look across the next row, and so on. It's not a great user experience and it is trumped by looking through a physical library to look at and scan with the eyes. at this stage of the game, I think it should be at least as good, in that respect, as looking through a physical library.
Scrolling should be really smooth. It's key to making the control point enjoyable to use and not make it feel like a compromise. Is smooth scrolling and fast drawing going to be difficult to achieve because of multi-platform requirements? I had my hopes up that this would be solved with Kazoo.
