Been playing a little more, and there's some big problems with graphics settings.
I've been playing the game at 1920x1200 on 'fantastic', and getting 60ish fps. The game plays fine. Then decided to try it on the 'fastest' setting, at the same resolution. 500+ fps, but big problems. Firstly, the cursor was glitching. It was flashing/vibrating as if the refresh rate was wrong. The controls suddenly became way too sensitive, I could only place the balls at the extremes of the pitch.
The comments about extra turn with spinners are true, but I didn't expect it to be this drastic. On fantastic, I was getting not a huge amount of turn. Probably the width of the stumps at best, ie. googly pitching on off would go to hit leg, maybe just clip it. On fastest, it became ludicrous. I went around the wicket, bowled a legbreak as far wide on the leg side as possible, as short as possible (held down right+down keys) and the ball pitched, way way off the square, and spun so far that it missed off stump. Not even close, it was a fair way wide of off stump. Same thing happened with the googly. The topspinner, a length ball became a vicious bouncer, and the flipper, a long hop would bounce 3 times, a half-tracker would just roll.
The pacer was also getting ridiculous movement, a ball which would be wide on the off side, short, was moved in so much that it missed the batsman and went down the leg side.
These are things I don't think have been fully detailed, so I thought I'd make a point of it.
