I have a Toshiba Satellite L855-12G with 8GB RAM. I am running Directx 11 and have checked the system requirements of games such as 'War Thunder' and 'Outlast'. I should be more than capable of running these games at optimal quality. Despite this, in 'Outlast' for example, I am struggling to even get 5 frames per second and that's just in the main menu. In 'War Thunder' I get between 12 and 18 frames per second on low quality. According to www.systemrequirementslab.com I should be able to run the game on at least high quality. I have checked that drivers are up to date and they are. Should I consider replacing my graphics card? Or is there anything else I can do? Any help would be greatly appreciated.
