Personally I have been using LWP for 2 days and I notice no unnatural lag at all. I am running at 550 mhz and it seems to run so smooth. When I was using the sholesmod ROM I thought it was quite laggy, even if I overclocked (which I preferred not to, to preserve battery). Today was my first day of work w LWP enabled and I think my battery has fared the same, if not better, than the usual. I am using BB 0.6 and using the Neural Network LWP. Does anyone know the kind of load Neural puts on the CPU or how much battery it uses (a lot, little?)? I might just stick to static wallpapers, because battery life is kind of a priority to me.
Also, are there any figures for the improvement of ESE53 over ERE25? Like the increase in battery life, performance, call quality, etc, etc?
