Just coming back to say it runs fine on:
Q6600, 2GB Ram, Nvidia 8800 GTS 640 and Windows XP 32bit
Both computers run QLive through Firefox, a few add-ons are different but the big ones are NoScript (Set to allow), ABP, Skype extension, AVG Link Scan, Greasemonkey and Proxy U93 add-on (Which I do not use).
It can't be the laptop's graphic card (9200GS) that isn't powerful enough, because the very same card runs WH40k Soulstorm maxed out, UT2004 on Normal, UT99 maxed out, Audiosurf on low 960x600... Something to do with configuration somewhere, but I don't have any ideas... Maybe disable CPU throttling for a start, but it's Vista and I have no idea where to do that (Desktop with the 8800 GTS is set to "Always On" in the power management which effectively disables CPU throttle afaik).
Anyways, while playing on the desktop I finally managed to get my KDR over 1 for the game I was playing, almost around 2. Usually it's around .7, .8... :/
