- Fixed precision int math
- 64-bit int division
- wasn't supported in the supervisor context, drop into a worker thread for each individual division, do double division
- 64-bit int division
- Avoid recursive algorithms, e.g. make a non-recursive Binary Space Partitioning algorithm
- Split column rendering over 32 tiles
- Memory
- Save 50-60k of lookup tabes for transcendentals by using float functions
- Store textures on other tiles, JIT-fetch as needed (by live patching exchange programs to select a tile)
- Can call exchanges from deep in the call stack, don't need to exit the vertex
- Texture tiles also do colour mapping to create shadow effects (light dropoff)
- Render tiles issue dummy requests after finishing to allow unfinished tiles to keep syncing
- Transcendental lookups -> live calc
openings(used for masked objects) is 40K, surely can be smaller on striped render tiles- cut down on width of
visplane.top/bottom,columnofs, etc due to samller screen widths - remove cachedheight, cacheddistance, cachedxstep, cachedystep?
- gamemodes other than shareware
- multiplayer
- cheating
