I use Raptr (AMD Gaming Evolved) to set optimal video settings which is pretty higher than every game's recommended values. Unfortunately, all installed high end games are not listed in the software and hence I have to put forth my own values in video settings of all non-listed. When I use recommended, the settings go either normal or low -> (especially the Saints Row IV). I can change it high but I don't know exactly what are all should be changed so that the game play will have neither lag nor stuttering. I use MSI R9 270X OC. Should I use any other third party software or go trial by manual troubleshooting?
