MoI3D : Same story, its a little but more cpu intensive, but not that much. The gui has to be scaled up (high dpi option in Houdini prefs) Cpu stay moslty on idle all the time, I could probably run Houdini for 10 hours. Houdini : I will not generate fluid simulation with the Pocket, but for modeling / prototyping it works very well. I`m really surprised how well this softwares are running.
I have no idea how to monitor the clock speed on Ubuntu, but by judging the fan noise, I really doubt the cpu runs at 480Mhz. Ubuntu resource monitor report that the cpu usage of the video player (totem) is about 8%, but compiz (?) is also using an other 7%.
My guess is that Ubuntu doesn't support (by default) hardware decoding ? But maybe there is something to do about it (better driver ?, using an other video player ?). Using one of those players, HWMonitor shows that cpu is constantly locked at 480Mhz, with an average of 10% cpu usage. (VLC 2.6 gives more less the same draining rate than ubuntu) This is only true of I use win10 default video player, or VLC 3.0. One hour of video cost almost 20-25% of the battery life, while the same file on windows 10 will drain maybe 10% of the battery. However something that really bugs me, it`s how fast I drain the battery when reading H.264/MPEG-4 AAC videos (720p).
I really love to use Ubuntu on my pocket, especially because I find it more readable than Win10 on this little screen size.
