DOSBox is fast, it's you that needs a computer upgrade........ and probably a dosbox upgrade

Still wondering if there's any way to getting a Intel HD Audio driver for MSS\AIL or if a TSR to "emulate" a SB16 is feasible...

okay leileilol explain why in dosbox i never get runtime error 200? i guess that means dosbox is not working at high cpu Hz values, it emulates low machines, while NTVDM uses high cpu Hz values, probably the same as actual(real) cpu.
so why i need super tractor to run tetris? loool, fool.
DosBox is very good for compatibility but not for speed, its slow, because it emulates cpu on os, while NTVDM probably emulates dos and runs direclty on hardware.

So its just guesses, if you are proffesionals here, okay, than just explain me how i can run chasm in windows xp while i can run games released in 2012 year, i dont need upgrade because i hate new games but i can run them too in my PC. so pros explain me this phenomen??????????????

Quake has no vsync and the game timer can exceed 70fps on stock dos quake. You'll have to compensate with huge resolutions, which 1280x1024 is the max, and will still be too fast most likely.

quake runs in dos using athlon 64x2 at 2,6 Ghz in 320x200 resolution without any problems you mention, i guess should work in intel i7 too, i can run at max resolution ant is works great no slowdowns

because you never have cycles=max in your config, or your dosbox is so old it predates the addition of cycles=auto (and possibly the dynamic recompiler).

i have max cycles in my config i even press ctrl+f12 to make 105% my dosbox is 0.74 i dont think newer versions have adventage,
the truth is :
http://www.dosbox.com/wiki/Performance (there is test app http://web.archive.org/web/20060201052402/htt … IL/speedtst.zip )
in dosbox i can get 357 mHz cpu
if i run this app in WinXP it reports me 2601 mHz cpu (so NTVDM win here)

Please recommend me some special dosbox build and/or special cfg where i can get maximum mHz cpu)
P.S. I like you leileilol, you awesome person =)!!!! its 100% truth =)

Every instruction in dosbox is 1 cycle, 357mhz is false. So you need a computer upgrade

(btw speedtst in dosbox reports a "3850mhz" here, if you like to believe in meaningless theoretical clock speed)

Could a TSR provide SB16 emulation?

Yes, with issues. I remember Sound Blaster Live! had a TSR for emulation of older Sound Blasters.
In some games it worked, in some it did not. And of course it took conventional memory, which is always precious.

And before Live, Gravis Ultrasound also had such a TSR called SBOS, which sometimes even worked.

The only program that could use SBLive natively was said Mpxplay (under plain DOS only, not even Win9x)

It's not that modern soundcards cannot be used under DOS (they can, as mpxplay shows), it's just that new cards aren't compatible with old Sound Blasters (they cannot be, you'd need an ISA bus for that)

so what i need to do exactly?

get a better machine or find out what limits the speed of Dosbox on your machine.

i have 546MHz on dosbox, the host CPU is
"
CPU Intel Pentium T4400 / 2.2 GHz
Number of Cores Dual-Core
Cache L2 - 1 MB
64-bit Computing Yes
Data Bus Speed 800 MHz
Chipset Type Mobile Intel GL40 Express
"

not enough?
athlon 64 x2 2,6 gHz not enough?

are you insane here?

what processors you have? but i think problems not in CPU in DOSBOX itself

It shouldn't be that slow on that machine. So I think the problem is rather with your machine than with Dosbox.

it all times slow on either of my 2 PC's no matter what OS i install i tryed it on WinXP And Win7 and several times reinstalled them nothing help =(

Yeah, MPXPLAY... That's what always made me feel adventurous in hacking a literal digital sound driver for Intel HD Audio under MSS\AIL. Though yeah, conventional memory being a problem for TSR usage but I'm primarily only going to be playing stuff that runs in 32-bit Protected Mode... would I still run into issues there?

Speed Test's results are written in XT equivalent. Numbers with MHz is not benchmark itself, it's a try to identify what CPU you are using.
Also Speed Test would not take into account additional sound and SVGA load. Besides some games may to have closer or farther correlation with it. If you have no Runtime 200 issue, then your emulation may to be below P200 for that game. You may compare you CPU emulation speed in my thread in the signature.

P.S. I like you leileilol, you awesome person =)!!!! its 100% truth =)

Yeh, you both are like yin/yan of same nature.

Who knows? Perhaps no one tried that yet... It's doable in principle, though I cannot guarantee that you won't run into an unsolvable showstopper.

And if normal means fail, modern CPUs have hardware-assisted virtualization (Ring -1), so you could emulate all hardware you need from there, putting whole DOS into a virtual machine. But that would be a lot of work.

Speaking of hardware VM's, someone linked me to this really bizarre product, I don't have a link anymore but it was a 16-bit ISA slot to USB. The page I remember being on was rather vague and it seemed like a gimmick to me, could that really drive a SB16 and make it usable? Would a hardware VM beable to directly use that device?

They've been discussed before, I think you're talking about the USB2ISA from ArsTech.

They're not cheap.

Yeah, that's the thing. Anybody have any experience with using legacy audio cards with that?
