Flash player lags full screen when having a single core processor

I’m having a HP 530 Intel celeron computer, with firefox on it. When i run a video on fullscreen mode in firefox the video lags…

A solution found on youtube was running firefox in windows xp sp3 compabitility mode but i’m not sure it works.

Other persons thought it was not adobe’s fault and it gived a fake virused executable.

Another one can be found here:




copy the file on desktop: c:\windows\system32\Macromed\Flash\FlashPlayerPlugin_20_0_0_286.exe

imagecfg -a 0x1 “C:\Users\George\Desktop\FlashPlayerPlugin_20_0_0_286.exe”

then copy the file again in the c:\windows\system32\Macromed\Flash folder

after doing this it’s a slight improvement but not really the happiest.
