Back around 2014 a friend of mine was interested in playing Skyrim on a laptop with a 4th gen Core i5-4200u CPU and Intel HD 4400 with a 1080p screen and 8GB of RAM. I have a pretty similar laptop, but it also had a Radeon HD 8850m dedicated GPU. I already had Skyrim installed on that laptop so I disabled the Radeon HD 8850m to force Skyrim to use the Intel HD 4400. I backed up the SkyrimPref.ini file before I stated to make a lot of edits.
The SkyrimPref.ini file has a lot of graphic settings that you cannot be changed in the game's graphics options. For example, the only way to disable shadows is to do it in the SkyrimPref.ini file. Disabling shadows can really improve performance, but I made a lot more edits than simply disabling...
