HYPNO: Slow frame rate, navigation issue and frequent sound pops
|Reported by:||antoniou79||Owned by:||neuromancer|
|Version:||Keywords:||audio, pops, frame rate|
Description (last modified by )
This from testing today with Steam version, on Windows 10, and ScummVM 2.7.0git from HEAD master, built with enable-release.
My observations in comparison to the game running on DosBox (which the Steam version uses):
- There are frequent "pops" in the audio, very noticeable during gameplay. Non-gameplay videos seem to not have this issue.
- The framerate in the gameplay feels significantly slower than when playing in DosBox, which feels faster and smoother.
- When playing in DosBox, moving the mouse towards the edges of the screen causes a bit of a navigation movement (like the view moves up or down or left or right). In the ScummVM version this does not seem to work.
Edit: The 1st issue with the audio pops does not seem to occur in current 2.6.0 stable daily, or it's very unnoticeable.

About the navigation issue; I've also noticed that this does work somewhat if you move the mouse to the edge of the screen -- it seems that it triggers just for a short movement when the mouse crosses a threshold to the right or left, but I have to retrigger it to make it move further.
For some reason this works like this in the full screen mode. In windowed mode, it's either harder to trigger, or does not work at all.
Thanks for the report!
This is a regression in 2.7git, which should be fixed here: https://github.com/scummvm/scummvm/commit/a31e1b63156141d2574fc29dbc1b92fc000dc1fd
This is an interesting issue. I don't have access to the original hardware which was supposed to run this game so I don't know how it played originally. The dosbox version is emulated, and depends on the your CPU speed (number of cycles, which I believe are not fixed). Some levels later in the game (e.g. the one with the motorcycle) seems to be much more difficult than expected, because the speed of the missiles (https://www.mobygames.com/game/wetlands/hints/hintId,915/). I can still tweak it to make it a little faster, but it will need some experimentation.
I was able to move this left or right moving the pointer near the edge, however it is not as smooth as expected. I think the code expects input events so moving a little the mouse should trigger the screen movement.
It is nice to know that the stable daily is a little more stable than 2.7. :)
