Gotten back into the game since 1.0, and spent an hour or so just playing around on my first planet.
But I do find that my game is quite laggy at times, at least as far as mining is concerned.
It'll often just stop mining while I'm holding down my mouse button, or it will take forever. And it gets worse the lower I go.
The game has a habit of reading all my clicks on menus as being double/triple clicks too, which isn't an issue outside the game, so I didn't think it's my mouse.
Bit annoying really. Haven't read through the topic recently, so I don't know if these are common issues.
