[Trisquel-users] Re : Screen tearing and high CPU

Not with free software. Because Dogers does not have an Intel integrated  
chipset, he swapped the card for a two-year older GeForce GT 630 and got much  
better performance (from 5 fps on Flightgear to 30):

But you have an Intel integrated chipset and they work great with Linux-libre  
(hence Trisquel). See, e.g.,  
https://www.phoronix.com/scan.php?page=article&item=intel-iris-6200 (but  
understand that the Fedora 22 uses proprietary firmware to drive the AMD and  
nVidia competitors).
