There's a lot of raycasts under the hood to make sure the AI works and I wonder if that might have something to do with this. In that case "strong enough to make games" requires a clarification as to what kind of games. Most 2d games that don't rely on physics are not going to tax any system at all, but with enough calculations I can see how less powerful systems might struggle. 

I have a pretty powerful desktop setup so it's always difficult for me to judge how it affects performance without having people test it. Sorry it doesn't run well for you :(
