Try these settings.
Machine settings -> Model settings -> SID settings
Disable Emulate filters.
Strangely it was already disabled
Machine settings -> Model settings -> SID settings -> SID Model
Change it to 6581 (FastSID).
This is the thing that speeded emulation the most!
FastSID. I can hear sometimes glitches but they are really rare. This should be in A320 set up
Sound settings -> Buffer size 45 msec
It's possible that it still needs a little longer. Default is 100 msec but that's too long and I noticed that if it's too long it slowsdown the sound emulation.
I forgot to say in the previous post that I lowered it to 40msec from 100. At 45msc sound starts to glitch...
Fragment size -> Medium
That seems to be the best size for the Dingoo A-380 with Synchronization method Exact.
In A320 it has to be on very large. On medium it is catastrophic, on large it glitches sometimes, but on very large it even gains some more fps and sound is not distorted.
So, after few days this is the fastest set up that I made so I would have the most fps in Laser Squad intro but without music distortion:
A320 SETUP for highest fpsSID chip
6581 (FastSID)Buffer size
40Fragment size
Very largeFrequency
22050HzSynchronization method
FlexibleSpeed settings ->Refresh rate ->
AutomaticThat gives the 46 - 50 fps in the intro.
Now, It is possible to make a setup that has less fps, but the sound would be much better. You don't see many dropped frames with this setup, but fps number is lower. You should have in mind that many games for C64 would still work at 50fps with it (I tried Bounces, Lazy Jones, Lasersquad in game, Boulder dash, Antiriad... etc and they worked at 50fps)
A320 SETUP for most games with quality soundSID chip
6581 (FastSID) or
6581(ReSID) (slower than FastSID but better sound)
Buffer size
40Fragment size
Very largeFrequency
44100HzSynchronization method
ExactSpeed settings ->Refresh rate ->
AutomaticI hope that this will be helpful to anyone using it in OD.
The main difference is that A380 is faster than A320 and so A320 has to have different settings.
By the way, this should be posted in Dingux-releases part of the forum too. It is a releas for OD too, isn't it?
