Before upgrade I have used latest version of Firefox 3, and performance was good enough. I do not found this issue with other site - only this one slowed down noticeably. Note: above url is for Polish version of the game. There is also Deutsch version and few others. Unfortunately English version is not available yet - http://en.kapihospital.com/ says "coming soon". Reproducible: Always Steps to Reproduce: Register on http://en.kapihospital.com/ and try playing Actual Results: Game works very slow, 100% CPU consumption (or 50% on 2-core CPU) Expected Results: Game should work the same or better as in Firefox 3
Version: unspecified → 2.0 Branch
In safe mode problem also exists.
I searched a bit and looks that this is related to rendering engine in F4. My graphic card is GeForce2 MX/MX 400, so it is quite old. I have upgraded its drivers and DirectX to newest versions, but without luck. I also set layers.acceleration.force-enabled, gfx.direct2d.force-enabled and webgl.force-enabled to true, but this did not help. about:support now provides following information about graphics (I translate from Polish, English names may be a bit different): Graphics Adapter: NVIDIA GeForce2 MX/MX 400 Supplier ID: 10de Device ID: 0110 RAM: Unknown Adapter Driver: nv4_disp Driver version: 6.14.10.9371 Driver date: 10-22-2006 Direct2D enabled: disabled in driver. Recommended upgrade to 257.21 version DirectWrite enabled: false (0.0.0.0, font cache n/a) WebGL renderer: (WebGL unavailable) Windows with hardware acceleration: 0/1 Mentioned page uses many animated images. When I stopped animation by pressing Esc, performance greatly improved. However this is just workaround, not real solution. Any ideas how to solve this issue?
Maybe related to Bug 595671?
Probably yes - there are ~50 animated images on the page.
Is the performance ok if you open "about:config" and change "image.animation_mode" to "none" ? In that case i would mark this as dupe of bug 595671
