Due to lack of A530 hardware, I can't do anything here and hence unassign this ticket, so someone else can take over. |

Yeah, the Floppy release is quiet slow. A faster Cpu wont help here. The Blitterspeed/Routine is the Bottleneck/Cap. There is a interview with Andrew Morris where he gets asked about the slowdowns/ low framerate. https://www.youtube.com/watch?v=SM5yXZarVYM&t=306s The "CD32/AGA" version is faster. (its still OCS tho) Sadly the CD32 Version is not supported yet by a WHDLoad Slave. (you would loose the music, because those are CDDA Tracks on the Cd32 version) There is however a hacked CD32 version of Lotus 3 out there that tried to improve that speed even further and hacked all the Music from the Floppy back into the Cd32 release. (can´t remember who did it .. maybe i find it later then i´ll post a link) The JST version of Lotus 3 also runs better then the WHDload version. (slightly) One thing you can try is to only play with the SFX. No Music !! It WILL run smoother. (that was the reason Lotus 2 had no music during gameplay) (Lotus 1 had cut the screen in half to give you both) One again, the Chip Speed is the bottleneck. (check your Chip speed in Sysinfo) But currently, only Chip Speed makes the game smoother. (and becomes REALLY smooth with more and more of that) Thats easy to do on FPGA or WinUAE. I dont know the A530, but by the sound of it, i think it only boosts the Dhrystones. I play on FPGA, but if you want to have the smoothest Lotus3 possible right now on your setup, hunt down the hacked Cd32 version or get at least the JST installed one. Turn OFF the Music for now ... (i know that sucks , but you get better framerate, trust me) Maybe one day support for that CD32 or the hacked CD32 version drops, maybe with patched routines for Fast-Ram. But that would be a huge undertaking. Dont know if that will ever happen, but one can hope ;) PS: Sorry for the long Text Wall, but its a thing with Lotus 3 ... you know ;) greetz, Torti |

Found it !!! The hacked Cd32 version is called. LotusFix 1.0 by Thomas!/SP (17.04.94) (sadly, the turran site gives me a 404 on that) BUT the same is contained in a generic WHDload install by Aladin. https://ftp2.grandis.nu/turran/FTP/Non%20TOSEC%20Games/WHDLoad/Aladin%20WHDLG/LotusTrilogyCD32-WHDL.lha Run it native (without the generic WHDload slave) Its the smoothest version of Lotus 3 so far. (maybe you need to assign CD0: "" .. cant remember. I use the JST version because it can quit, is a bit faster then the WHDLoad option and on FPGA Chip Speed is not a problem. Hope that helps. Have a nice day. Torti |

Well the game is super slow on A530 it is much slower than normal version. It is one of the problems with A530 where CHIPRAM access is super slow. Half the speed of normal Amiga. There was a suggestion to rewrite slave so it will use only fastmem or something along those lines. That might help with a530. |

Hmmmmm,i see ... (T_T) Well, to rewrite the slave would not only benefit A530 owners. Support for the CD32/hacked version would be also really nice ;) |

For sure. I would love to see the better version of this slave. And probably not only me. |

After discussion on the EAB forum, it seems this is due to A530 slowing down (to less than half speed) access to chip memory compared to stock A500, which makes this not a WHDLoad problem. I'm therefore closing this. |
