Even with these outdated specs , I can still create and run my games. I get a decent variation from 25 FPS to 40 FPS when running the latest build of zeroXgen. It is by far, not the best gaming rig , and is also outperformed in many areas of performance when compared to entry level rigs from 2013, which is when I bought it. But hey , it gets the little jobs done and still outputs a decent FPS , when I build an optimized 3d level.
It also helps that I use every trick I know , when optimizing my 3d games.
