Can anyone advise on which version of Nvidia driver works best with Flash 10.1 for GPU acceleration on an Asrock ION330?, I have tried Flash 10,1,53,64 with nividia drivers 185.55, 195.55 and 257.21, All give the same jittery results when playing HD content on BBC I-player, Note :- I can stream the same content over the same broadband connenction to a Dell desktop with no jitter at all.
