Windows 8 doesn't like PTE ?

[denisb]

Hello,
on a specific slideshow, with a kind of time-lapse and zoom, there was a lack of fluidity (jump).

I made a small example (100 jpeg pictures) to estimate roughly the minimum slide duration needed.

With my PC (2009):
Intel Core 2 Quad Q8300 @ 2.50GHz
1024MB GeForce GT 220 (MSI)
Windows 7 64 bits

The minimum slide duration is 0.19 s for jpeg pictures 1920x1080 (374 ko)

For an up to date PC(2015):

INTEL Core i7 4790K Unlocked 4.0Ghz LGA 1150
RAM DDR3 - 32 Go
GeForce GTX980 G1.Gaming SOC 4G
2 x SSD PLEXTOR M6Pro Xtrem Series 256GB PlexTurbo
Windows 8.1 64 Bits

The minimum duration is 0.25 s

You can see (in French) examples : http://www.diapositif.net/forum/viewtopic.php?f=55&t=39300&start=0
It show that the problem is PTE slideshow on Windows 8.1 OS.

The slideshow is attached. Select the time duration and look at the progress bar.

Regards

Denis

On my Windows 8.4 64 bit OS with an i7 4770 CPU (8 CPU's) @ 3.40 GHZ and 32768 MB RAM Direct X 11 and a GeFprce GTx 760 with 2 Gigabytes RAM 192 bit running on a 30" 2650x1600 pixel display, the .30 and .25 are smooth and others all jerky.

On my Win XP Home Edition with a Core 2 DUO 2.33 GHZ with maximum RAM (4 gigabytes installed) and a good GeForce GTX 750 Ti with also 2 gigabytes RAM running Direct X 9.0c. None are completely smooth. .30 hiccups a bit and the others all jerk.

Best regards,

Lin

I don't have Windows 8, but for test purposes, on W7 Professional, the top item was jerky, the rest smooth.

Denis,

Thanks for this question. PicturesToExe is not optimized to show quickly series of large images in the executable format.

0.2 or 0.3 second is not enough interval to load JPEG images (1920x1080) in time. The practical limit may vary from computer to computer. And that problem will occur on any version of Windows.

For time lapse, I recommend to create MP4 video. The file will be very small due to good optimization.

Igor,

I agree that the value itself 0.2 or 0.3 s is good enough and the example is just to évaluate the time needed.

The real slideshow was with larger image (zoom effect) each second.

The surprise was that the time under windows 8.1 is larger than the time needed under windows 7.

I don't know why, but i suppose you know.
