Feature Foxit reader; GPU acceleration

[danwat1234]

Hello, I am currently using version 2.2 of Foxit reader, and obviously it has no form of GPU acceleration. In what version of Foxit reader did it gain the ability to take advantage of a GPU to help smooth scrolling in a large (300+ pages) picture (not necessarily vector) based pdf?

I am running a 3.3GHZ Core 2 duo Penryn CPU and CPU usage spikes to nearly a full core for the Foxit process when I am scrolling at moderate speeds and it is not completely smooth. It really should be, as my CPU isn't a dinosaur by any means. I have an Nvidia 9800m GS video card with Cuda 1.1 support

EDIT: I should note that the pdf is 886 pages and 480MB, so like 0.5MB per page.
EDIT: From the changelogs of foxit reader, version 4.1.0.0726 has the following fix;
-Optimized the reading engine and fixed the issue where the scrolling becomes very slowly when reading large PDFs.

Also Adobe reader 8.x has 2D GPU acceleration for zooming, panning, scrolling.
I'll try foxit 4100726 first.

Our latest version is 5.1.4, would you mind upgrading to it and give it a try?

No go

I tried both Foxit reader 4.100726 and 5.14.0104 but neither had any improvement in scroll speed for this document.

Also, I'm not happy with the bloat. Going from version 2.2 to 5.14, the installed size in program files went from 5.98MiB to 32.7MiB and RAM usage, without any pdf loaded went from 12MB to 45MB, and then disabling the startup screen in 5.14 brought it down to 22MB.


I'll try Adobe Reader 8.0 now.
All right, so I tried Adobe reader now and it ballooned up to using 1GB of RAM in no time when I was scrolling, and scrolling was FAR worse than any foxit version.


EDIT:
On Adobe under 'Page Display' there is a 'Use 2D GPU Acceleration' checkbox. Checking it or unchecking it and restarting the software doesn't help the scrolling. Adobe isn't doing memory garbage collection like it should.

In both Adobe and Foxit, there is the 'Reading' section in preferences, I guess that just applies when I want it to audibly read pages to me.

No, the bottleneck is not related to the speed of my hard drive, as I have it on a SSD and I have a high amount of free RAM.

EDIT:
Anybody want to give this pdf file a go to see if you can run it smoothly? Here it is, on filefactory:

If you decide to download it, you'll need 7zip to uncompress the archive.
Please state what CPU your using and the clockspeed, the PDF reader you are using, and if you can, CPU usage in task manager of your reader process when scrolling at different speeds and from different zoom levels.

Thanks!

Thanks for the update.I failed to access the link, would you mind directly sending it as attachment to [email protected] so we could forward to our QA team for further testing?Thank you.

No, that won't work. The file is a bit over 300MB in size and I doubt your email system will take more than 25MB.
The file seems to still be up on filefactory. You have to click on 'slow download', enter the CAPTCHA, wait 30 seconds and then click the red 'click here to download now' button and the download will begin.
