Most games provide the ability to set an FPS-limit. This has multiple purposes. For example, it might help keep hardware cool - prevent overheating. Is there some mechanism in FF4 similar to an an fps limiter or limit to monitor’s refresh rate?
Now, right now there are a lot of D2D related performance regressions, which will most likely be fixed (Beta 8?).
That is all fine and dandy, but are there any plans or ideas for future performance improvements for GPU-assisted rendering for FF4.1 and on?
Offtopic: due to things like CUDA, does it make any sense to offload JS to the GPU?
Oh and for encouragement: I noticed is that IE9 is really great at its own tests, but horrible at real world performance. While, Firefox seems to balance the two. :D
]]>While I can force FF to keep my NVidia GPU at maximum clock-rate via the NVidia control panel I cannot enforce FF to use Vertical Sync. This leads to FF rendering up to over 100 fps (FRAPS) even when the screen is running only at 50 or 60 Hz.
According to FRAPS FF keeps rendering at an average of 16 fps even when *nothing* is moved, scrolled, changed, blinking or whatever (not even the mouse being moved).
Trying to run FF with Hardware Acc. in Parallels Desktop 6 leads to crashing FF right after being started. The same happens with IE9 though and the detection mechanism of FF seems to turn acc. off by default.
]]>Currently we’re doing our main window compositing with D3D9. This is so that we can also offer some level of hardware acceleration to our Windows XP users. The interoperation required here to work with D2D is expensive though. We’re working on doing composition with D3D10 when using Direct2D, in order to speed things up.
An additional reason that we have a bit of a disadvantage is that since we’re a cross-platform browser. All our drawing commands arrive at Direct2D through an abstraction layer like Cairo, this makes it a little bit more complicated for us to optimize certain situations. We are most certainly working on it though!
It’s also great to see that IE9 is making such good progress, healthy competition in the browser market is good for all the users!

1779 IE9 x64
1574 FF4 x64
Any insight in whats going on with the first one? Anything on the horizon that will adress this?
]]>However, anyone else encountered a bug where if you load something intensive (e.g. IE fish tank demo with max fish), and then try to resize firefox, the whole window stops responding? Specifically i can’t click on anything on my computer until I alt-tab.
I’m on Windows 7 64 bit, with an ATI Radeon HD 5400 series card.
