DamienD's WinUAE Collection - Page 106

Maybe I am wrong, but I think anything other than a 68020 will decrease performance. Emulated CPUs are different from real CPUs. I remember this was a tip from Toni himself.

I have never looked but do you use JIT or is it just the standard settings?

Pretty much standard settings... so no, I never use JIT...

Out of 2760 games there are only two configurations that I found JIT to be necessary:

Code:

  C:\WinUAE\Configurations\Day of the Tentacle [AGA]   [ScummVM].uae (1 hit)
  C:\WinUAE\Configurations\TFX [AGA].uae (1 hit)

Interesting, I know it can screw up on some games which is why I guess you don't but it helps to speed up a lot of games.

I just checked Quake and well your using it there too

Ooops... yes you are correct; Quake also

All three games run like a dog without JIT enabled; no matter what CPU / with "Fastest possible" selected.

I know, ran TFX on an A1200 with a Blizzard 030 back in the day and it ran like crap, in the end had to get it on PC lol.

I think would be nice if Toni shed some light to the subject...

Toni Wilen · 06 July 2019, 17:14

Answer is as usual: it depends. Basic modes modes have identical speed (68020 to 68060) but more compatible etc.. options can make it slower. This is simply side-effect of more complex emulation. For example 68030 instruction cache is not identical to 68020 instruction cache. Both have same size but internal layout is different.

Leandro Jardim · 06 July 2019, 21:39

The three configurations above have the "more compatible" option enabled, so they will lose performance with it.

Damien, excuse me, but are you really sure it makes a difference for better to enable a 68030 in your computer?

Would not it be better to change the setting back to a 68020, since it would not matter as the only difference between them is the "more compatible" option and if you untick it, it will have the same speed as an 68020 as Toni explained? (just to make sure it will not get any worse)

Sorry if I am annoying you Damien, I am not wanting to "take control" of you, and my intention as an user of your game collection is that more and more users download and install your creation.

Sincerely,

Leandro

I don't think selecting a 68020 instead of a 68030 CPU or unticking "More compatible" makes much difference; at least not on my laptop; which is an old Acer Aspire 5951G purchased at the end of 2011...

Anyway, you can always test yourself from your computer and see

DamienD · 07 July 2019, 16:00

Ok, I just played around with the configuration file for Payback.

I tried:

Leaving as is currently i.e. a 68030 CPU selected, "More compatible" ticked and running.
Leaving a 68030 CPU selected, just unticking "More compatible" and running.
Changing from a 68030 CPU --> 68020 CPU, leaving "More compatible" ticked and running.
Changing from a 68030 CPU --> 68020 CPU, unticking "More compatible" and then running.

To be honest, I didn't notice any difference; and importantly, with "More compatible" unticked.

Just as an FYI, I only really set a 68030 CPU for hardcore / intensive games and usually follow the notes on HOL, when specified, about requirements.

Boulder · 08 July 2019, 21:25

Regarding Sim City, I suggest that you change the game into the 512K version. It plays much smoother on an A500 and the only difference is that the 1 meg version has slightly better graphics. The 1 meg version gets very, very slow after you grow a big city and it takes forever to finish a single year (I noticed this back in the day when I played it on my old A500). In fact, I was just trying to play it and it seems much slower already from the start than what it was on a real machine. Don't know if it matters whether I use full screen or windowed mode.

DamienD · 09 July 2019, 12:00

Hi Boulder,

Interesting, to be honest I've never really played the game for more than 5 minutes as it's not really my type of game.

I guess I could change the configuration to an A1200 one which should improve performance; tested and this seems to work fine.

If you don't mind, as you're an experienced player, try doing this yourself and let me know if all is good.

enigma776 · 09 July 2019, 17:07

Changed the config to A1200 myself and it does work alot better with Sim City. Maybe a recommended update on the next update pack.

You are right, there is not any difference. I really had not noticed that you have done that before with many games in the collection.

Sorry for the doubt. Thanks.

No problem Leandro

When I create configurations for high-end games; trust me, I try various different options to get the best performance but adhere to the specified requirements as much as possible.

Thank you Toni for stopping what you were doing to give your opinion. A thousand apologies for the inconvenience!

Yes, I agree with this suggestion. The game seems much smoother with the A1200 config.

Ok, as long as you guys don't think that this will cause any issues.

...as an FYI, if I loaded the game, selected the scenario "Tokyo", the monster seemed to attack almost immediately when using an AGA config which never happened with an OCS / ECS config.

I just hope that events / other things aren't too sped up by this change

Anyway, here's the update for now; which I can always reverse... Bounder, please test thoroughly / compare gameplay wise with the original config if you don't mind?

Just extract the attached into "C:\WinUAE".

Boulder · 10 July 2019, 20:10

I played it shortly and at least no weird graphical effects or anything like that appeared.

However, a weird thing I noticed, and I think this also happened with the old config. At least if I pause the game at the beginning of the game to add the power plant and some zones, the game seems to process only when I open the Maps and Graphs screen. If I don't open that screen, I can leave the game in Fastest speed but time doesn't pass at all. Anyone else have the same behaviour?
