Firefox running slow and choppy

I have an nVidia 8600GT card (made by EVGA) on a machine with Windows Vista (AMD Athlon X2 processors) and four gigs of ram. It runs pretty good, but I have had some slow/choppy/stuterring video playback issues whenever watching flash videos on Youtube or other sites. The problem is there with both Firefox and IE flash videos, but is maybe worse with Firefox. I also tried Linux with nVidia's binary drivers and it was about the same. I downloaded EVGA precision which allows me to control stuff like the fan and clock speed. The card's temp (in both Vista and Linux) is usually at 66C when idle (not playing a game or watching anything). It goes up a little when watching a video (maybe 68-72C).Any ideas on how to fix this?UPDATE: The issues are both with full screen and embedded flash videos. I have Flash 10.0.32.18 (always make sure I use most recent for security), and the CPU is an AMD Athlon 64 X2 Dual Core Processor 4000+ at 2.11 GHZ. The current GPU driver installed is the most recent GeForce one from last July.

I think it starts at Flash 9.0.115.0.What type of CPU do you have? It's possible the bottleneck is not with the GPU. answered Aug 17, 2009 at 14:28 GrantGrant2,9651 gold badge19 silver badges14 bronze badges 6 try and run the the flash WITHOUT hardware acceleration(right click on screen go to properties). this will put it in software rendering mode. something to do with NVIDIA's 8 series cards. Should be fixed with adobe flash player 10.1 beta with GPU acceleration. answered Nov 22, 2009 at 8:49 mikemike5802 silver badges6 bronze badges Ok, I've struggled with this for a while. I only have the problem when on a high resolution (that's desktop area.) Also I have the problem anytime I have the graphics card is changing what's on my display. Ie. I could be running factorals and maxing my CPU and it'll play no problem, but if I scroll the audio gets choppy. I found the best way to test it is with Windows media player. When I have the visualization showing it's audio and video are choppy. But if I go to another tab or cover up the visualization (or even choose a simple visualization like "bars") the audio is smooth.I fixed it by doing the following on Windows Vista. I'm not sure if all steps are neccesary but since I can't duplicate the problem anymore I can't narrow down which step fixed it. First I uninstalled and reinstalled my Nvidia graphics drivers. That didn't work. Then I opened the run window and type "msconfig". Disabled all non-microsoft services under the startup tab. Then rebooted. When it came back up I loaded a song in WMP with a crazy visualization running. It got choppy. I opened task
