MT32 emulation now slows down most games (on Windows 7)
When I play Sierra and Lucasarts games with MT-32 emulation selected, the games now play at a usually unbearably slow speed with stuttered sound. I'm using the latest daily snapshot on a Windows 7 machine. Is anyone else having this problem? The last time I played games in ScummVM regularly was back in December, and there was no such slow-down. Also, I've tried playing several of the games on my MUNT-equipped version of DOSBox, and all the games run at acceptable speeds.

I'm using the Win-32bit version of ScummVM as well, but my Windows 7 is 64-bit. I don't rightly understand why it's causing problems now. Whenever I start a game (in full screen mode) the screen turns white, and the Windows 'wait' cursor appears for a bit, and then the game proceeds, but a white border is left on the right and bottom.

That's a good idea. I tried using 1.5.0 again, and I'm having the same problem. I don't know where to get an older build. I believe 1.4.x worked just fine.
But I've been told that MUNT was updated at some point recently, and that it may be more processor-intensive, so I wonder if that might be what's going on. I have noticed that the music DOES sound a lot more like a real MT-32.

Old versions - including some really old ones - are archived in the files section of the ScummVM SourceForge page.CaptainJei wrote:I don't know where to get an older build.

I suspect that MI is right. I have an old 1.6 GHz Dual Opteron machine with XP and it can barely handle a lot of more modern higher demand stuff like media in comparison with my other, newer machines. The Munt emulation does take some CPU muscle, This is not that noticeable on newer machines, but 1.6 is half of what many modern CPUs are.
The Munt developers are concentrating more of their efforts on accuracy than optimization.

Okay, this is strange... I reinstalled ScummVM 1.4.0, and once again the games ran at full speed (with admittedly less Rolandy music). Then I downloaded the latest snapshot and installed that, and now the games don't play nearly as slow with MT-32 emulation as they did before. There's still a slow-down during certain graphical effects (e.g. fading, pixel-at-a-time screen changes), but it's usually not game crippling anymore.
I'm not going to complain. Thanks for everyone's help!
