- OK perhaps I'm biassed because my Amiga is in a network and I get
- annoyed when my Amiga stops because -someone else- on the network
- starts playing an OS-killing game. On the other hand, even in a
- non-network environment, I've seen plenty of disk lockups, clocks
- showing the wrong times, failed zmodem downloads and even the
- occasional corrupted hard disks caused by Disable() for too long, not
- to mention the number of OS-killing games/demos that simply can't read
- my A3000 keyboard or handle my non-zero VBR.

- Once an input handler is installed, the difference is less than 1%.
- That is insignificant compared with differences between different
- Amiga models and configurations, different algorithms, probably even
- the time taken to render different frames in the same game.

- Did you try an input-handler?
