Firefox 3.7a5-pre ,received an update on the 21 of may, Windows 7 (64),amd x2 550,ati 5770 . This build has Direct2D acceleration enabled,and directwrite enabled.

java bitmap 600:buffer:strategy:647.63 fps
:buffer:image :43.5 fps

i know you might be busy but is it possible to check if this could affect mozilla .if not maybe ask website builder and all to change
from image to strategy or whatever its called in hid code.20 fps i dont bother.but thisits 600 fps more hell everything on the web can be designed with this in mind.ty
keep up the good work!

Also working great here on d×9 x1600 on vista sp2 with platform update. Google maps and especially the photo resizing demo are noticeably faster and smoother (10% cpu usage compared to 50 - 60% with gdi enabled). I would definitely say that its worth it even for lowly wddm 1.0 cards, rendering wasn’t noticeably faster, but scrolling etc. is much, much smoother.

Please, Please also provide opengl acceleration for all the firefox linux users out there !
isn’t there a experimental cairo-gl backend (not the glitz one) in recent cairo versions ?

Awesome! It works decently on a ati x1600 mobility video card. Obviously it doesn’t rull at full accel (some pic/text pages lag) but for 80% of the web sites i view it works pretty well. I have the blurry text problem though. It would be interesting to see how a PGO build handles. Perhaps a nicely tuned PGO build could compensate for older cards.

By the way - if I go into fullscreen mode in your version of Firefox the artefacts do not appear when scrolling up and down. But outside of fullscreen mode they do appear.

Might be helpful in tracking down why this happens :-)

@Stebs: Well, I’m no expert on the subject either, but in theory, 10.1 cards would support some higher shader model versions. It could be that D2D will be able to use that to optimize certain operations a bit more. But generally I’d say there shouldn’t be a significant performance impact.

Got a slightly OT Question about Direct2D (after a fierce discussion in another forum about it):

Is there any performance or feature difference between DX 10.0 and DX 10.1 Hardware for your Direct2D accelerated Firefox?
-Given one uses Windows7, latest DX API and WDDM 1.1 Drivers for both Cards.
Some say that only 10.1 Hardware (ATI Cards and only some recent Nividia Cards) does provide full performance, but I don’t see it that way (10.0 Hardware with WDDM 1.1 Drivers are “enough” for full performance).
Thanks for any clarification!
