Just opening up Google Chrome slows my AOCLBF Phoenix 1.5 miner down from 430 MH/s to 383 MH/s ...
Does this happen for anybody else?
It does not do this with IE 9...
Chrome uses your GPU for rendering the website(not only for displaying it). Therefore, Phoenix gets less MH/s
By the way, so do the current versions of FireFox and the latest internet explorer.
If you want to stay CPU only, stick with firefox 3.6 or use FireFox 4/5 and disable GPU accelleration(google it, I dunno how to because I use FF3.6)
AFAIR Google Chrome has an option to disable GPU accelleration too, as I'm on windows xp that option is invisible to me, as XP does only provide limited support for GPU acceleration so it's hardly used by chrome, therefore cannot be disabled.
