NzBeagle:jarledb: Wow, that is a big difference. Wonder why that is, would expect the screens to get faster not slower.
Worrying trend too
The VT60 is not afflicted with the same problem. Its actually less laggy than last year's models (the GT60 too, but we aren't getting those).
The reason for the lag is probably due to the lesser processor (SoC) on the ST60 and the way the smart functions are handled this year.
As is the case this year, the ST50 models didn't share the same dual-core processor that was in the GT and VT.
When using the smart features (internet services like youtube etc), all models had to load the service up before they had access to the various functions. This brief loading took longer on the ST50. When the smart features are not used, they aren't a burden on the processor's resources.
This year, Panasonic seems to have made the smart functionality (My Smart Home) as an always on tap service so that when you decide to hit the Home button, you'll get access immediately without loading.
The 'Hexacore' processor on the VT is likely coping with this burden and the ST's MediaTek SoC is not.
The other thing to support this theory is that the S60 model has the same (or lesser) processor as the ST60 but it doesn't feature My Smart Home. It doesn't suffer the same lag problems...
So if you like your gaming more than you care about having Facebook or Youtube on your TV, then the ST60 is a bit of a letdown.
