Is not the same the original BlitzQuake (that didn't work for 95% Amigas) to my developments of it over the years using almost the same minigl (with small corrections at the time). Old warp 3D programs out there have issues but people tend to test their cpu performance with those ( as Gears3D demo ) as references. On top of that, a simple shitty cable used for hd connection or whatever hardware situation, makes a warp3d program unstable by default when it run good on other machines. |

I think we talked way back about this, and one theory was that the Mediator->Amiga Motherboard bandwidth was just being eaten up by all of the other traffic. Even though we used a more CPU intensive soundtrack like MP3 or OGG, performance actually increased. That is-unless you used an actual CD Drive and the audio output was just handled by the hardware mixer. |

I (think) I experimented a little with removing XA/CDDA playing but the result was that not all background music was removed or some of the effects were disabled aswell. Probably was game dependent and the fact is every game has different behave while emulated: Some have distorted sounds if they render cpu intensive scenes and others have desynchronized backing track for some seconds but with clean playing and no distortion/stuttering. Also some games have irq signals that aren't emulated properly because every one of them does it differently and the procedure here is hardcore disassembly in realtime and see what they do. Now multiply the work for every PSX game around (and being a fulltime psx hacker going to the rabbit hole). |

New mini-upgrade (beta3b) that seems to increase a little the framerate for G2 ppc cards.

Will there be a 68k version as well?
I noticed someone on Discord reported running psx on the pistorm. I think it was the Amidog version, it was playable with overclocked pi to 2.2ghz. Perhaps an improved version could run well with less overclock. |
