Crashes:
I have had three crashes so far. The first was when I was breaching a very small UFO probe, with a soldier equipped with a shield. The shield got shot, and the game crashed. I had also blown up a wall of the UFO. The next crash occurred right after, as I launched the game for the second time. The third crash happened after a successful mission, on the return to base.
Performance:
Frame rate has consistently been above 300 FPS, topping at about 800 FPS in the HQ (running "Fantastic" graphic settings)
Some models have some jagged edges on them, namely the human combatants.
No stuttering.
