The PW3 allows user installed fonts and if the file is a suitable AZW3, embedded fonts in the book. At least with the current and previous FW that allows themes.
Iv'e only seen slow page turns on H20 using poorly formatted PDF image files. Regular plain epubs are fine. As an aside, to avoid risk of PDF / Postscript malware, Image Magick now won't process PDFs at all. You can change None to Write (safely) in the security properties. This is for PDFs that are really images/scans and from smaller books/manuals, not Letter or A4 size magazines etc. OPTIONALLY: Open the PDF and print to PDF (easy in Linux, add one in Windows or use a PDF viewer with one included) and resize to A5. Then read a PDF into Gimp as layers setting the larger axis to 1024 pixels resolution scale, then Export as .mng format. then Code:
convert stories-ireland.mng -reverse -type Grayscale -threshold 55% -crop 610x958+34+34 +repage test.pdf Adjust the XY size and X & Y offsets to remove blank margin, watch out for mirrored page formatting, crop must suit even & odd pages. It makes the PDF fit on the page and background white. The PDF then page turns at a reasonable speed. I've never had a problem with epub2, old mobi or azw3/KF8 formatted ebooks that are created or converted by Calibre on any ereader for page turn. I set to refresh every page. But then I'm reading not flicking through. Calibre, nor Adobe, MS or anything else won't convert PDFs that aren't really just text. Last edited by Quoth; 05-13-2019 at 04:23 PM. |

I never meant to imply that the A7 was older than the A9, it's indeed not . (For our purposes, a valid chronology would be A8 -> A9 -> A7).
Unfortunately, if you're concerned about how the CPU stands on its own, comparing the Kobo software to the Kindle SW is like comparing apples to oranges: A Kindle will *always* feel snappier. You can put a Clara against a PW4, the PW4 will also trounce it, despite both running the same SoC. As has been mentioned in this thread, things are better if you stick to KePubs, but, still, if you put both side-by-side, lab126 wins, no matter the SoC . EDIT: That video also specifically tests the Manga reader, which is pathologically slow on Kobo, *much* more so than either of their ePub renderers. EDIT²: For people not running test benches, and actually using their device to read books, the behavior of a Kobo Mk.7 is perfectly fine in day to day usage. Then again, I don't consider reading Manga/Comics on eInk a viable usecase, so, that punts off the worst offender to "don't care" territory for me . Last edited by NiLuJe; 05-22-2019 at 09:10 AM. |

have you tried those Android ereaders? many are using quad core A9 or 8 core A53 cpu, alth the system are far less stable than Kindle or Kobo system. but running the Koreader-apk it's fast, faster than their bulit-in apps
I don't know what's the scale of HW related to performance, but avoid big screen ereaders like the 13" or 10.3" ones, the screens not good looking enough with the now tech, the screens are the bottleneck, small 6" screens are mature, the big ones not |

I haven't had any experience with Android eInk devices, no, but your comment sounds similar to @pazos', who's been fighting tooth and nail to get some of 'em to behave in KOReader .
