Slowdown problem in PPC Warp3D software

[Mugo]

     Hello guys,

   Let's see if i manage to explain the problem, in english . . .

   Everytime i run some software that uses Warp3D on my PPC, i have slowdowns every second (aproximately).
   
   Take as an example the GLQuake WOS. The game runs fine, and the demo starts. But the movie goes jumpy. It runs fine and then slows down, then goes fine again, and aproximately one second after that, it slows down again, and that goes on and on.

   This happens when i'm playing the game as well, and so for every PPC Warp3D stuff i tried: Wipeout, Sopoblock, d3GNOP, Alybox, and even the Warp3d Gears demo.

   Do someone have the same problem here ?

   Do you guys know what can cause such problem ?

   I appreciate any help. Really !

   Thank you guys.

   Edit:

   Forgot to give some configuration details:

   A4000D (in a tower), Cyberstorm PPC (Stock, not overclocked) with 128MB FastRam, CVision PPC, Mediator 4000D, Voodoo 3 3000, Realtek Ethernet, Video Toaster 4000, SCSI HD in Cyberstorm's SCSI interface, IDE CD-Rom in the Motherboard IDE interface.

   As for the software side, i have two OS3.9 installs. One that i've used all my life, with lots of patches and everything, and the Amikit, that i've managed to adapt to run on my system. In the Amikit install i have the original installation, except for the Mediator drivers, and Warp3D for Mediator, as well as the Picasso drivers for the Voodoo on Mediator. Everything else is what came with Amikit.

   In both systems, the behaviour is the same.

   Thanks !

        Hey Quenthal,

There is quite a lot of patches in AmiKit, that could cause your problems.

1) Remember, that when copying stuff directly from AmiKit, that there are some versions of software compiled for 68060, while versions in AmiKit are usually for 68020 etc. You can ofcourse get much more performance out of your machine when using correct libraries and utilities

      I had to make some (a lot of) tweaking to make the Amikit work on my real Amiga.
      I did it most for experiment purposes.
      I hadn't time yet to replace the programs that I'll use, for the right versions, but that was my first intension.
      In the process of making Amikit work in my A4000, i've left behind some programs and utilities, as for example the taskbar (forgot the name).
      All in all, the system is a bit slower than my previous install, but is quite useable.

2) Check that if there is some program doing something that requires switching between 68k/PPC - if it is every second, maybe you have some sort of screensaver polling, clock or taskmanager etc. Especially that MemTrailer -patch that is used in AmiKit might make your Amiga slower.

      Yeah . . . you've got it.
      The problem is now solved.
      It was the GLMatrix, that i've replaced for the WOS version, that was "competing" with my games and Warp3D stuff.
      Now everything is smooth again.
      I need to find the problem in my former install tough, as the same occurs there.
      But now i know where to look for.
      The problem sounded very obvious after you mentioned it ;-)
      Thank you very much, and all the people that gave their input as well.
