I bought a Surface Pro 1 on Ebay. I am using it for ROS but I am going overseas and needed something to do so I installed Civ V. I know that the surface can handle the game on the lowest setting since my roommate played it on his surface pro 1 for about 6 hours. when I first ran the game, the surface quickly got hot in about ten minutes. I checked the CPU usage and it was near 95%. My initial thoughts was that it had something to do with windows hardware not running windows OS. It is not dual booted since the surface came with a Chinese version of Windows 8 (there was no way to change the language settings). It only has Ubuntu 16.04.
The next day, I watched about 20 min. of a movie before it started to get uncomfortably hot. To get the temperature i used:
sensors
I ran Civ V in the background again after setting ti the use "Processor microcode firmware for intel CPUs from intel-microcode (proprietary)" under the additional drivers setting.
Some specs:
Surface Pro 1 i5 3317u
4 GB RAM
128GB SSD
Ubuntu 16.04.2 LTS
I've been looking around for solutions to the heating issue. I have not found much. the little I did was tried above. I'm wanting to know if it is a hardware and/or software issue so that I can return it if need be.
