60fps, lags heavily anyway

If your GPU is too slow, you shouldn't see 60 vps usually, but I guess it depends on the video card driver and its settings. At least for me, I have plenty of games that undertax my CPU, but my GPU can't handle more than 600 or 1200 vps (I use a "green edition" underclocked GeForce 9800 GT, but have a nice powerful Ivy Bridge i7.)

I would suggest you try a recent git build instead of 0.7.6. They're a bit lower down on the downloads page. They're less stable, but right now they're a lot improved over 0.7.6.

The latest git builds also have control customization under Settings -> Controls. Not sure if that will help your prolem with Digimon.
