With Crossover Games 9.1 I had two crashes with Far Cry bad enough for me to delete the bottle rather than risk using it again. The first happened after I tried to increase some graphics settings - the game advises it needs to be relaunched but on doing so it just bounced in the dock and couldn't be force quit. I tried quitting then force quitting all the other apps I had open to try and restart but they wouldn't close either - even the window manager wouldn't quit via activity monitor so a forced logout failed. A hard shutdown was eventually necessary. When the computer rebooted I tried launching Far Cry again and got a hard freeze immediately - the mouse cursor locked. Twice was enough for me hence my deleting the bottle. I'm not sure what low level stuff was being accessed that could cause that - crashing apps I can live with but hard freezes and kernel panics are awful.
