Increased "White Flash" in newest updates???
-
@mediamogul Thanks for the kind words, and thanks you and @TMNTturtlguy for testing.
I did make the carousel top speed slightly slower, you are correct. If it's too noticeable, I'm happy to either add it as an option, or revert it. The reason is that, with the previous top speed, it would eventually show white flashes as it couldn't keep up with the required texture loading at that speed.
For simple calculations, what that speed meant was that every 150ms it would move to another system - so, in effect, it was trying to load (in theory) between 6 and 7 systems per second. For each system, we effectively load their logo and background, and buffer the neighbor logos and backgrounds, so we were loading in the best case scenario 6-7 systems * logo * background = 12-14 images per second, assuming it would re-use the neighbor ones in memory and not have to recycle them in memory. If a system has more than one image (i.e. background and overlay), you can effectively double that.
There's a significant throughput demand in those cases, either from SD card to memory to GPU, or just between memory and GPU, so slowing it down to 200ms makes it cycle (in theory) through 5 systems per second.
I thought it'd be a reasonable compromise, from testing, whereby you still get reasonably fast scrolling, but no longer experience a lot of blank textures from loading (unless the system does slow down for some reason, or maybe your textures take up more memory, or are not as compressed in the SD card).
The buffering helped mitigate some of this - so, if you cycle by 5 systems per second, it makes sense to try to pre-load/buffer the next 4-5 you're expected to load, just in case. And slowing it down to 5 systems per second helped keep this manageable within the memory constraints. They work hand in hand, complementing each other, rather than having been done in order for the other to work. Just to understand, previously we were caching only 1-2 extra systems forward and back at all times, but loading 6-7 per second meant that you couldn't keep up easily. When you were requesting the 3rd system to load, it wouldn't yet have fully loaded, and it would start loading as you were moving to the 4th - it was a losing proposition at all times.
Truth be told, for the masochist in me, I could try to get it to pre-buffer 7 and see if I can revert the speed back to where it was. Just out of curiosity.
Thanks for keeping up with this, all of you.

@pjft riding in the car to my meeting, thanks for the great explanation and detail on what you did. I actually found the slower cycling in slide a positive. It still moves much faster than anyone needs anyways. The whole feel of the movement and how clean each system logo and background loaded was so nice it just felt right! That being said, I need to spend more time with it, but I think the slower speed is very nice and would not recommend making an option or spending to much time on it. Just my opinion.

@TMNTturtlguy thanks. Yeah, I don't like to add options for the sake of adding them, there's an art in picking the right defaults.
That being said, fixing this did in effect bring a slower "fastest" scrolling that nobody had asked for, so even though it's a compromise, I can certainly see it as being a bargain that some didn't even ask for in the first place, and as much as I can rationalize that for myself, it's not something I ultimately like to pursue without validation.
I've also been on the receiving end of "minor UI changes" in apps that I use, that most people perhaps thought weren't relevant but ultimately affected me or my user experience negatively, so I'm open to feedback on that If people do complain. :)

I agree. The speed isn't a big deal. I have 41 entries altogether on the carousel and I'm still able to get from one end to another in a reasonable time. I certainly wouldn't complain about more speed either if it's something you end up experimenting with, but what you have done already is remarkable.

@mediamogul 41 systems! That is amazing, do you have video/meta data for all of that?
Staying on topic, well stated.
-
do you have video/meta data for all of that?
I have metadata and basic images for at least 90 percent of the games. Whatever can't be caught by Selph's scraper or the one built into ES, I don't stress over.
-
@pjft @mediamogul inspired by, but not to one up @mediamogul I loaded up 40 systems with the comic book theme, and it ran like a dream! Now, that being said, 20 of the systems only had 7 games in them, but they were all loaded with video and images! Nice work @pjft truly amazing stuff that you accomplished this week.
-
@TMNTturtlguy I may have a small request for you on the side, not urgent and certainly not in any way important, but perhaps useful for 3-6-9 months down the line for ES. And likely none of these will result in anything.
I'll reach out at a later stage, either via here or via GitHub.

@pjft Sounds Great, just let me know!
-
@pjft I just had 62 systems running when final testing the theme - ran super smooth!
