Btw. I used the Sysinfo in order to see how much difference is between a real A1200 values in comparison to quickstart A1200, and for this case I used/watched only the "Dhrystone" value, other values was not much important. And what I found is that the cases 2 and 3 are pretty close to a real A1200 and quickstart is pretty far. I hoped that this could helped to improve the quickstart (read slow down) but I was maybe wrong. Anyway, I am going to use this instead of quickstart as the testing shows that works fine. (long story short) Trying to make 020/030 to work cycle-exact is close to impossible task IMHO! (it is just not possible without knowing what happens inside) What is possible now is to observe whats happening "outside" and then according to findings adapt the emulated cpu to run the most possible programs. (in this case some still problematic demos left) I was tired to wait when it will happen, so I decided to try something by playing with the winuae and (by chance) found cases 2 and 3. (and I am pretty satisfied with these already) You can still have two types configurations for A1200: one that strive for cycle-exact accuracy and one that is adapted to max demos work fine ! Quote:

@amilo3438
however, some anomalies you notice, is because cpu at default is too fast i notice this inconvenient also in real Amiga with fast processor like 68040. Some demos made only for A1200 run very fast and so distorted. maybe it is not only a problem of cpu.. |

i'd like to know if in WinUAE could be implemented a code like this (relative to cpu timing):

Excuse me if I ask a question without reading the whole of this great thread..
Read a few pages back the thread seems stuck on getting demo's working on faster settings than perhaps the target machine was meant to be, is it not better to make sure the demo works as planned on the target machine using as near to the exact same running conditions ie CPU speed etc as would the real machine be and then if it works on higher spec its a bonus. I appreciate there are some very high spec machines out there with demo's written for them but Toni has always been clear about the support of higher end machines and the issues around them being worked out slowly. Amilo and Toni have done some amazing testing and fixing on all the standard Amiga models but I think I'm seeing an over clocking trend? Should it still not be 'as per the real hardware first and then the exotic'? Apologies if I've entered the thread and missed a point...Keep up the wonderful work people...And thanks |

Trust me, I love the idea of seeing stuff running smoother, when I had my real 1200 and Viper(?) 68030 card the first thing I put on was FA 18 Interceptor and Frontier to see the speed and smoothness of the graphics but I feel there needs to be at some point a default list of machines and additional cards pre set up to match spec in the wild so bug reporting is narrowed down a load. Obviously Toni could / would have clear flags to should it was an altered machine. I would imagine that this is the plan anyway and its simply down to the nailing down the snaggy aspects.. |

A1200 Quickstart (Basic), "Freezers-Lech" demo problem!
If "Filter Settings" = "none" and "Line mode" = "Double" -> drastic slowdown just after "buildings" part" is finished! But if "Filter Settings" = "Null filter" and "Line mode" = "Double" -> seems fine Or, if "Filter Settings" = "none" and "Line mode" = "Scanlines" -> seems fine Fine in WinUAE 2.8.0 but problematic from WinUAE 2.8.1 (tested with attached config)!

Why are you using such an ancient version of WinUAE?
Surely you should be testing with v3.5.0 to see if the issue is still present... |

Filter=none is direct write to VRAM surface/texture. Do not use unless you have some really old DirectDraw-only display card.

Now, I am not sure is it happens because of my old PC laptop old drivers or is it something else, but CPU usage goes till 1000% after "Building" part finish. Quote:
Strange that it works fine in 2.8.0. and problematic in 2.8.1! (in DirectDraw or D3D) EDIT: As mentioned in post #128; no problem when "Filter Settings" = "none" if "Line mode" = "Scanlines", but only problem if "Line mode" = "Double"! (just tested: fine also if Line modes = "Single", "Double, fields" or "Double, fields+"!) Last edited by amilo3438; 14 August 2017 at 12:19. |

...surely it's time to get a new computer and then start testing with the latest version of WinUAE. It probably isn't helpful if you are providing bug reports using old ancient versions and with 10+ year old hardware... |

To get a new laptop just for testing latest version of WinUAE ? (joke, right?) (Unless someone ready to donate one specially for this purpose.) Last edited by amilo3438; 14 August 2017 at 12:42. |

I would say clearly not!

Imagine going to the MAME Devs with bug reports; I guarantee you they would say "get a more modern laptop!". Toni's just too polite to say this to you and drop support for Windows XP. |

Well, unless you know how to adjust (read optimize) to make them work acceptable on old hardware.
(Usually default settings, even on WinUAE, is not adjusted for old hardware requirements.) PS. I think you agree that this discussion does not belong to this topic, so please delete or move it somewhere else. (Thx) Btw. While it still work on WinXP I guess its supported.

Last thing I'll say on the matter...
You are completely missing the point here and are probably providing bogus bug reports by: a) Using an old, very slow laptop that's not up to the specs required for intensive Amiga demos and stuff. b) Using an ancient version of WinUAE. c) Using Windows XP; which is no longer supported by Microsoft, therefore nobody bothers writing new drivers / stuff. You would probably find that these bugs would not exist if you were to use: a) A modern computer / laptop with enough grunt (and we are not talking top of the range here). b) The latest WinUAE. How difficult is the above to understand? I have an old ThinkPad T42 laptop with Windows XP installed sitting in my cupboard. There's no way I'd be using this to test / provide bug reports for anything... Last edited by DamienD; 14 August 2017 at 14:27. |

We already have similar discussion but on other topic!
Hope you didnt forget Mission Elevator sound problem -> http://eab.abime.net/showthread.php?t=85023&page=4 Note: That problem was noticed/find on my old hardware too! |

<sigh>
Mission Elevator; what's that got to do with it?!? ...running old 1987, OCS games on crappy hardware is no comparison to running intensive AGA demos really... it is well known that AGA needs more grunt and especially for a lot of the demos that pushed the hardware back in the day. I bet you are the only person on EAB that still uses Windows XP as their main machine. Maybe I should try contacting the Call of Duty authors to let them know that it doesn't run on my laptop and ask them to magically fix instead of upgrading? Anyway, nothing more to say on the matter and again you're completely missing the point. Last edited by DamienD; 14 August 2017 at 15:40. |

XP is "supported": it runs, with basic options. Everything else is undefined, any new feature may not work.
(And Mission Elevator problem had absolutely nothing to do with PC hardware) |

One question!
In WinUAE 3.6.0 beta series topic, does this graphics problem happen to other users too or its because of my old hardware? (when tested on WinUAE 3.6.0b1) http://eab.abime.net/showpost.php?p=1178014&postcount=5 (Or maybe it's time to stop report similar problems as my hardware is too old now.)
