I usually check these while buying games but lately one or two titles said I couldn't run them well and yet they are actually running well for me. ME Andromeda runs smooth and fast and according to "Can you run it" I couldn't but I am. Graphic settings on high. Agents Of Mayhem, below spec slightly on my CPU but the game is running fine on medium settings. So are specs a definitive guideline? How can you tell if a game definitely won't run unless you try it? Pity devs don't do more in the way of actual demos you can try. Even Dishonored 1 and 2 run fine on my hardware. I think both are set to high. I have very modest budget hardware. I'm looking at Mafia III and told it won't work well so downloading the demo to see for myself.
