Stuttering, Small freezes and framerate Issues

[nebej]

spidernetlabs you can continue on your old save, but the stuttering will only dissapear when you reach the next level. It requires a map to load fully for the stuttering to dissapear, which it doesnt do when loading a save file

I've done some more testing of different variations (all with the original *.snd and *.ogg files of course):

1. Original aamfp.exe, original main_settings.cfg, patched SDL2.dll, new profile, new game: Stutters.
   
2. Second aamfp_stutter.exe, original main_settings.cfg, original SDL2.dll, new profile, new game: Slightly better! Some freezes vanished. Don't know why I didn't notice on first test. Still stutteres when walking through doors.
   
3. Latest aamfp_stutter.exe, original main_settings.cfg, original SDL2.dll, new profile, loaded game: Same as 2.
   
4. Latest aamfp_stutter.exe, original main_settings.cfg, patched SDL2.dll, new profile, new game: Same as 2.
   
5. Latest aamfp_stutter.exe, lowered main_settings.cfg (32, 4, 131072), original SDL2.dll, new profile, new game: Much better! No more reproducable stutters!
   
6. Latest aamfp_stutter.exe, lowered main_settings.cfg, original SDL2.dll, new profile, loaded game: Same as 5.
   
7. Latest aamfp_stutter.exe, lowered main_settings.cfg, original SDL2.dll, old profile (created by original aamfp.exe), loaded game: Stutteres!
   

So as they saied, you definitly have to create a new profile and start a new game using the latest aamfp_stutter.exe, or it won't work! Seems I can finally start playing this awesome game. But not before tonight, with lights of and headphones on.

Nice finds! Im gonna see if we should reduce the number of streams to 4 too see if that fixes the problem for more people

Ok, thanks.

I also lowered MaxChannels and StreamBufferSize and it helped. I'm looking forward to test the new patch.

Much better for me with the second stutter patch!

(Core i7 965, gtx 670 Sli, 12GB, Windows 7 64 bits).

Still some very little stutters, but finally playable

But one question, you need the Sd2.DLL to use this exe, no? Whitout it you can't launch the game, am I wrong?

Maybe you could put all the necessary files in the same .rar for future users.

The unpatched game already includes a version of the SDL2.dll. The new version from the sdl2_test_patch.zip is apparently not necessary for fixing the stuttering. (At least not for me)

If I can bother you to test a bit more. What happens with:

MaxChannels="64" StreamBuffers="4" StreamBufferSize="262144"

MaxChannels="64" StreamBuffers="8" StreamBufferSize="131072"

Just to check if we really need to lower all three. For reference the original Amnesia uses:
MaxChannels="32" StreamBuffers="4" StreamBufferSize="262144"

1. MaxChannels="32" StreamBuffers="4" StreamBufferSize="131072": No reproducable stutters.
   
2. MaxChannels="64" StreamBuffers="4" StreamBufferSize="262144": Noticable stutters e.g. when walking through doors or at the piano-shock.
   
3. MaxChannels="64" StreamBuffers="8" StreamBufferSize="131072": Same as 2.
   
4. MaxChannels="32" StreamBuffers="4" StreamBufferSize="262144": Same as 2.
   

In all above mentioned scenarios some stutteres disappeared (compared to the unpatched aamfp.exe), eg. when the thunder sets in near the attic window.

Someone else should also test this and confirm or refute my findings!

Strange, maybe with the steam version. For my GOG version I had to download a version of the SDL2.dll...

Alright, thanks! Yes, would be nice if someone else also can test.

I'll go over and also change some sounds that currently streams to be loaded to memory instead, because else I think there will be quite often situations where not all sounds get to play. Basically music, voices and base ambient sound is streaming, so will change so that only music and voices stream. Then 4 stream buffers should be enough.

So messing with the audio in cfg file works only if i start a new game with a new profile ?

Ok it works for me too, 0 stuttering so happy now, i need to start the game from the beginning now...but at least i dont have stuttering.

Now i need to open the game from the aampf_stutter.exe everytme ?

[Stangi]

Why are some sounds streamed at all? I mean, wouldn't it be better to preload all of it? I don't imagine it would affect the loading times drastically...?
