For a 0-127, 128-255 split the if should be > 127, not > 128 I would think.

Curious, would the compiler optimize the if statement out of the for loop or would the following optimization be needed to do so? Also, the original >128 if compare makes the split lopsided by 1, 0-128, 129-256, intentional? void Mixer_SetSample16Table(void) { for (Bitu i=0;i<=128;i++) Sample_16_ …

Based on the criteria of oldest computer game you actually like, Beneath Apple Manor 1978 Apple II. It's on a PC, I like it well enough, and it's the oldest fitting the criteria, failing that Smooth Max 1979 Apple II which I like better but Beneath Apple Manor seems to fit. I liked Zork which came …

I'd think old driver source would be more interesting, nvidias particularlly, but w9x source I could imagine some people wanting to go back to scratch old itches, get past the 512mb limit, past 30 day uptime, remove the do not run if not microsoft checks, see how compatible they could make it with …

I remember munt being cpu heavy making it being a separate process a good thing. Has it become efficient enough to live in the same process with little impact or added as a separate thread?

A new toy to play with, threaded cycle handling. doom, 3dbench, diag report better results but quake isn't impressed, worse fps. Also changed the max from 90 to 100% Anyone know the problem games that led to limiting cpu usage to 90%? I haven't run across anything that has issues at 100, most games …

Tidings and salutations, I bring news! Not fixed yet but I've narrowed it down, playing around locking various things to see the impact, lots of no difference but locking ret = (*cpudecoder)(); in Normal_Loop(void) in dosbox.cpp gets dac playback to run error free, albeit slowly. Continue going down …

There hasn't been a what's better EAX vs A3D debate(A3D BTW,) a "they aren't equivalent, I didn't mean that, given the way it was written that's how it was taken" interaction is what transpired. Nothing, except maybe price and availability, is stopping you from getting both (i.e. Creative and …

There's setting "max" cycles and do once more it sets to 105% and then doesn't allow the user to go higher, which I'm looking to undo, would expect it to be a simple change to keep going with 110, 115, etc., I thought that handling wouldn't be so hard to spot, I was wrong. Maybe I've been away from …

Directly, no, but per the English language inferred, "..only an issue if you care about a3d.. that said, most of these games also support eax." At least how I read it more so than a separate statement.

Turn of the century A3D 2.0 games come to mind. Stuff like Deus Ex and Voyager Elite Force. This is only an issue if you care about A3D since Aureal Vortex cards don't work correctly under anything newer than Win9x. That said, most of these games also support EAX which works just fine under WinXP. …

Ah, you threw me, pic stuff, as in irq, not pic stuff, as in audio video capture. I'll run through that , might even be the fix for the dac bug.

What did you test with? Something with fm and dac playback I hope? I also accidentally left a log_msg running, did you comment that out? Another thing to do is cut the "max" headroom by about half.

>You also need locks around all the pic stuff Not from what I see, what CAPTURE_AddWave touches that's referenced outside of it comes down to capture.video.audioused and capture.video.audiobuf, which is what got locked.

Um, different animal, one is threading, the other I just put the guts of mixer_mix into mixer_callback, calling mixer_callback from mixer_mix, which seemingly produced a slight improvement, but doesn't mesh with the threading. Attached is threaded mixer_mix diff using sdl_delay and put back sdl_lock …
