- So, those games I was playing on this 486DX2-66 (hardly overpowered by today's
- standards) in XFree86 under Linux were entirely my imagination were they?
- Admittedly they weren't graphically stunning, but there was no noticeable
- flicker even at full-screen (1024x768, 256 colours). (My favourite is xbill,
- which runs in a fairly small window but allows one to shoot the multiple
- copies of Bill Gates which swarm around a group of non-Windows computers in
- the middle attempting to install them with Windows.)
