Quake already uses fixed point in some of the major bottlenecks (done by the pocketquake team, not me). There are still lots of other areas that use floating point but using the latest gcc speeds those up. Converting all of Quake to fixed point would be a massive job and I'm not sure how much of an impact it would have. The best thing to do would be to slowly convert other bottlenecks to fixed, but I don't know enough about optimising to know which areas are worth looking at (if any - it's possible the pocketquake team stopped optimising in that way because there wasn't much more that could be done). The bottom line is don't expect Quake to get much faster than it is now. Any speed improvements I'm looking at involve reducing quality and removing elements and increases will only be a fraction of a fps per improvement, not the 20fps increase you're hoping for.Octavious posted on Feb 9 2005 at 03:33 AM said:what sort of speeds do you think we could get from Quake/Quake 2 with fixed point?
