Define awful. If you mean the occasional blurriness, that's the game but not really, rather it's the fact that there's just no way to scale up a 612*384 (plus UI) texture to 1366*768 so that it looks good. Upscaling works better when you have a texture that was sampled from an analogue source or from something that mimics one (i.e. pictures), but even then it's not perfect. In this case though you *expect* to see particles being rendered as individual pixels and that makes all the difference. This does not necessarily apply if you're upscaling to a high enough resolution but in this case you're upscaling 612*384 to 1366*768, the latter of which is just not large enough compared to the former.
