Re: Demul v0.7 alpha released. (Dreamcast Emulator)

The amount of layers impacts performance quite a lot. Be aware though that some transparencies like smoke or dust will look glitchy if you set it too low. I think the smoke from the pots outside Man Mo Temple only look 100% right with 32 layers.

Re: Demul v0.7 alpha released. (Dreamcast Emulator)

Works great, I lowered the layers from 32 to 16 and it removed minor freezing in the opening. I assume lowering this value has some disadvantage though?

I've been using V-Sync since the last ver. (it smoothed out the game), but I use Nvidia's adaptive V-Sync as the emulator's V-Sync warped the audio for me.
From my tests 16 layers is all you need for Shenmue.

64 layers no difference at all except gives you lag if you raise internal resolution over x2 and it may crash your emulator.

I see notice no difference at all between 32 layers and 16 layers.Except as above explanation.

8 layers does makes a negative difference. I only saw it while practicing moves. If layers at 8 you will see Ryo white shirt through Ryo Jacket. Changing it to 16 layers and that does not happens.

I have not played the whole game to see if there any difference between 32 and 16 layers. But from my test I saw no differences.


Also Having 2x FXAA makes no difference at all. Just 1x FXAA is enough.
Its better to set x FXAA and another filter like Cartoon.
Cartoon makes the game more bright and makes plants more colorful and better looking.
But makes Ryo face looks a little weird.

Re: Demul v0.7 alpha released. (Dreamcast Emulator)

Here I did some testing with filters.

Trees look better with FFXAA on but other than trees I have not seen difference. If someone saw improvement in other areas please post screenshots.

Here the number 7 does not looks blurred.It looks better in my opinion.

Cartoon in my opinion can make a better job than FXAA it can make the game more colorful and bright and affects everything.It makes trees look more colorful and lively.

With Cartoon on coca cola machine looks very nice and bright and tomato signs too. It looks better with more internet resolution.

In my opinion 32 max layers is a most to have perfect emulation without graphical glitches during smoke or dust.
Filters FXAA does not make a huge difference. In my opinion is better to turn it off if it causes slowdowns.Its better to leave the anti-aliasing work to your graphics video card.

Cartoon is a better filter in my opinion. Turned both cartoon and FXAA makes no difference because you will only see Cartoon filter on.

Internal resolution x2 + 32 max layers is all you really need is very beautiful and is going to give you the HD feel.
It really depends on the size of your screen to take advantage of a higher internal resolution.

1x: 640x480.
2x: 1280x960.
3x: 1920x1440.
4x: 2560x1920.
5x: 3200x2400.
6x: 3840x2880.
