So I experimented a little and I compared the game settings with GPU-Z readings: On Low setting, GPU-Z shows 950MB dedicated, ~50 dynamic RAM, and the game is lag-free On High, it's 550/550 dedicated/dynamic RAM it stutters On All, it's 300/750 dedicated/dynamic RAM it also stutters So from my limit...

FPS and UPS are stable at 60FPS, then it lags, and they go down to ~52 for a bit. I can't take a picture without lags, because the fr...
