• i'm really quite certain that there was some ps2.0 only raytracing intro (64k or 4k, don't remember) a few years back, but i don't remember the name - can anyone help?
  
  that said, i know there's a snooker game that calculates exact intersection points+normals in the pixel shader to get nicer shading - again don't know the name, but it does get mentioned regularly on the directxdev ml when someone tries out perpixel lighting with spheres and wonders why they don't look perfectly round :)

• "first rayracer on gfx card prod so thumbs up"
  er, certainly not. i've seen some gpu-based raytracer in an intro (64k i think) back when ps2.0 was new, and half of the "high-tech" shaders people are doing nowadays involve some sort of raytracing. and there's also stuff like this, for example.

• kinda interesting to see firsthand how much brute force number crunching power is available in current graphics cards :)
  
  anyway, this is *really* short, so piggy i guess ;)

• 256b MS-Dos Demoplex by Digimind
• p01, it does need dosbox when you're sitting on a 64bit machine running a 64bit os :)

• demo MS-Dos Wild 8088 Corruption by Hornet [web]
• oswald, cycle counting on 8088 ain't that simple - normal cycle tables don't include instruction fetch time. on a 8086 this usually works out, but a 8088 only has a 8-bit data bus; it can basically execute most instructions a lot faster than it can fetch them from memory, and each opcode byte not in the prefetch queue means 4 cycles extra (and these penalties tend to accumulate).
  
  OTOH, i doubt it does make any difference for this demo, which (if i understand it correctly) basically sets up a few autoinit DMA transfers while the CPU sits around trying to get bytes from the HD as fast as possible :)

• demotool Windows kkrunchy by Farbrausch [web]
• deathy, i guess the .exe dropping played a big part in that; for kkrieger at least, after we noticed it is was mainly a matter of writing a few mails. no bitching no nothing, and it got removed on the next update in all cases :)
  
  crusader: well, that can ofcourse happen, but it's unlikely :)

• demotool Windows kkrunchy by Farbrausch [web]
• variant A (i.e. 0.23alpha) uses a pretty basic LZ+arithmetic algorithm (no, not LZMA; worse pack ratio, but smaller depacker). it's slow to compress but decompresses a lot faster (very roughly 2MB/sec on my P4 2.4GHz for typical data).
  
  A2 (0.23alpha2) is a context mixing based algorithm, akin to PAQ and crinkler (in fact I use the neural network mixer from PAQ7 with some simpler custom models). it's usually faster to pack than variant A, but takes just as long to depack (the algorithm is symmetric). i've spent quite some time (and sacrificed size too) to make average depack time reasonable for 64ks, but it's quite useless for anything much larger.
  
  main reason for the version number strangeness is that both started out as experimental branches that i later deemed good enough to release :) - 0.23final (should I get around to make it) will probably support both variants in the same executable. and expose some other nifty features too.
