only version 1.4.0 doesnt run right version 1.3.0 and earlier work flawlessly on medium quality with slight to no lag at all 1.4.0 runs on medium to low quality with slight to no lag but only crashes when entering bar on day 2 or later ive played slighty more intensive games with out any issues
Epic's website (the company that makes Unreal Engine) states that, the bare minimum specs to use just the editor by itself are,
Quad-core CPU @ 2.5GHz
8 GB of RAM
DirectX 11 capable GPU
You have a 2.5GHz CPU and a card that supports DirectX 11, so...
I'm going to assume you're running out of memory.
Also FYI; saying you've played more intensive games really doesn't mean anything... Performance optimizations have to be implemented by the developer, so they're not guaranteed at all.
That's why some games have worse performance than others even though they use the same engine.
