Yes, speed actually seems ok, might have been a fluke while I was on 8.0.1.0. Autofocus doesn't work during video recording in the default app though, so that might be a bug. Used to work fine in 8.0.1.0. Will try another cache wipe to make sure.
LE. Autofocus works after wiping cache, also some odd cpu and gpu behavior reported by cpuz seems to be solved(1big core was always stopped and gpu@490ghz).
However, now the 2 big cores are reported as always active(384mhz in idle)
LLE. after Antutu, the funny cpuz reports are back. One core always stopped, adreno@450mhz. Maybe cpuz bug or thermal throttling...Score is 63K vs 57k before wipe.
LLE. seems to be thermal throttling, cpuz readings are again normal after letting it rest for about 2 minutes.
