Now Windows can’t run on bad HDDs this has been my exerience in the past as well.. but Ubuntu will be able to boot up fine.. so i was able to check that all my data on the windows partitions were fine.. and then i called a computer guy. He heard the symptoms and agreed with my assessment. So off i went to replace the HDD. while doing that I realised i might as well do other upgrades. Since this is a notebook.. there arnt really that many upgrade options. So basically i got a new HDD and upped my RAM from 6 to 16gigs! yay!
After getting back home i proceeded to install windows(since most of my work programmes run on it) but instead of going back to the wndows 8(8.1) that i’d been using for the last year.. i decided to just go with the windows 7 that the machine shipped with. The primary reason being that in the last year the graphics drivers for windows 8 have been terrible.. it had affected both my gaming and 3d work performance.
Now with a spanking new windows+Ubuntu dual boot installation, I’ve been able to run Arkham Origins properly..
Of course the performance could be a result of the 16gigs of ram..The Nvidia and Intel graphics chips can now use 2-3gigs of it and i still have plenty left over for the rest..
but the stability is definitely a result of good drivers on windows 7. On windows 8 and 8.1 i frequently had graphics card crashes while modelling or gaming. Those arn’t happenning anymore.
Moral of the story, if your Dell XPS 15 L502X shipped with Windows 7 .. stick with it.
Note: I liked Windows 8, I’m one of the few people who didnt miss the start button, or had any issues with the metro ui start screen.. which is why i stuck with it for a year. But after a year of terrible gaming and graphics problems.. i’done with it. atleast on this machine anyway… well my next one might be one of those Ubuntu or SteamOS Alienware offerings.
