Zeewolf – speed cap?
I tried out one of my favourite games — Zeewolf 2 — on my A600 with Furia. Unfortunately the game played sluggishly, a bit too sluggish considering it was made for a basline A500/A1200 and the Furia is quite a bit faster.
Is there some kind of speed cap on Zeewolf? |

According to the WHDLoad readme caches and CPU features are enabled (and only disabled for 040/60 systems).

Indeed it does, and it's very fast RAM too.
Does this mean that the Blitter is the bottleneck in Zeewolf's performance? |

That's a possibility, or it could be hard-coded to a specific framerate like F1GP. But might it also be a WHDLoad patch (maybe a blitter wait or something) that doesn't quite suit the Furia? Are you running it from floppy or hard drive?

What's the chip RAM writing speed like for the Furia? Perhaps you have a version of Zeewolf 2 that's just not picking up the Fast RAM for some reason? (On the Minimig I use one of the crack ADFs - I'll try and remember to find out which one when I get home.) |

On A1200 040/40 Zeewolf 2 WHDLoad Slave 5.00 (15.08.05) it is sluggishly too.
I`m not sure about the readme if caches on 040/060 are disabled or not because: 2.01 ??/97 - disable instruction and data cache for 040/060 machines. [...] 3.01 07/99 - added patch for blitter wait function - added patch for self modifying code (caused crashes on 040/060) - enable caches and CPU features for maximum speed |

I suppose the caches are enabled as I was bugtesting for Girv with my A500/Blizzard 2060.

Hard drive with WHDload. Perhaps I should try out a plain floppy version.
