Hello,
I have an problem with my dosbox svn daum . I have installed in dosbox windows 98 second edition and dosbox emulate 3dfx voodooo card, but i have problem when i playing games, I have very low fps, for example : need for speed II se - 7 to 10 max fps, colin mcrae rally 2.0 - 4 to 6 max fps . It is because my emulated procesor in dosbox is 70 mhz, but most games colin2, nfs2,3 must be 233 mhz processor. I don't know what i must do.

# Nice = 0 - default
# Produces samples at double the volume, without tricks.
# Higher quality than the real devices
#
# Pure = 1
# Produces samples that exactly match the bits output from the emulated LA32.
# Nicer overdrive characteristics than the DAC hacks (it simply clips samples within range)
# Much less likely to overdrive than any other mode.
# Half the volume of any of the other modes, meaning its volume relative to the reverb
# output when mixed together directly will sound wrong. So, reverb level must be lowered.
# Perfect for developers while debugging 😀
#
# GENERATION1 = 2
# Re-orders the LA32 output bits as in early generation MT-32s (according to Wikipedia).
# Bit order at DAC (where each number represents the original LA32 output bit number, and XX means the bit is always low):

[sblaster]
# sbtype: Type of Soundblaster to emulate. gb is Gameblaster.
# Possible values: sb1, sb2, sbpro1, sbpro2, sb16, sb16vibra, gb, none.
# sbbase: The IO address of the soundblaster.
# Possible values: 220, 240, 260, 280, 2a0, 2c0, 2e0, 300.
# irq: The IRQ number of the soundblaster. Set to -1 to start DOSBox with the IRQ unassigned
# Possible values: 7, 5, 3, 9, 10, 11, 12.
# dma: The DMA number of the soundblaster. Set to -1 to start DOSBox with the IRQ unassigned
# Possible values: 1, 5, 0, 3, 6, 7.
# hdma: The High DMA number of the soundblaster. Set to -1 to start DOSBox with the IRQ unassigned
# Possible values: 1, 5, 0, 3, 6, 7.
# sbmixer: Allow the soundblaster mixer to modify the DOSBox mixer.
# oplmode: Type of OPL emulation. On 'auto' the mode is determined by sblaster type.
# All OPL modes are Adlib-compatible, except for 'cms'. sbtype=none
# together with oplmode=cms will emulate a Gameblaster.
# Possible values: auto, cms, opl2, dualopl2, opl3, none, hardware, hardwaregb.
# adlib force timer overflow on detect: If set, Adlib/OPL emulation will signal 'overflow' on timers after 50 I/O reads.
# This is a temporary hack to work around timing bugs noted in DOSBox-X. Certain
# games (Wolfenstein 3D) poll the Adlib status port a fixed number of times assuming
# that the poll loop takes long enough for the Adlib timer to run out. If the game
# cannot reliably detect Adlib at higher cycles counts, but can reliably detect at
# lower cycles counts, set this option.
# NOTE: Technically this decreases emulation accuracy, however it also reflects the
# fact that DOSBox-X's I/O timing code needs some work to better match the
# slowness of the ISA bus per I/O read in consideration of DOS games. So this
# option is ON by default.
# oplemu: Provider for the OPL emulation. compat might provide better quality (see oplrate as well).
# Possible values: default, compat, fast.
# oplrate: Sample rate of OPL music emulation. Use 49716 for highest quality (set the mixer rate accordingly).
# Possible values: 44100, 49716, 48000, 32000, 22050, 16000, 11025, 8000.
# hardwarebase: base address of the real hardware soundblaster:
# 210,220,230,240,250,260,280
# force dsp auto-init: Treat all single-cycle DSP commands as auto-init to keep playback going.
# This option is a workaround for DOS games or demos that use single-cycle DSP playback commands and
# have problems with missing the Sound Blaster IRQ under load. Do not enable unless you need this workaround.
# Needed for:
# - Extreme "lunatic" demo (1993)
# force goldplay: Always render Sound Blaster output sample-at-a-time. Testing option. You probably don't want to enable this.
# goldplay: Enable goldplay emulation.
# goldplay stereo: Enable workaround for goldplay stereo playback. Many DOS demos using this technique
# don't seem to know they need to double the frequency when programming the DSP time constant for Pro stereo output.
# If stereo playback seems to have artifacts consider enabling this option. For accurate emulation of Sound Blaster
# hardware, disable this option.
# dsp require interrupt acknowledge: If set, the DSP will halt DMA playback until IRQ acknowledgement occurs even in auto-init mode (SB16 behavior).
# If clear, IRQ acknowledgement will have no effect on auto-init playback (SB Pro and earlier & clone behavior)
# If set to 'auto' then behavior is determined by sbtype= setting.
# This is a setting for hardware accuracy in emulation. If audio briefly plays then stops then your DOS game
# and it's not using IRQ (but using DMA), try setting this option to 'false'
# dsp write busy delay: Amount of time in nanoseconds the DSP chip signals 'busy' after writing to the DSP (port 2xCh). Set to -1 to use card-specific defaults.
# WARNING: Setting the value too high (above 20000ns) may have detrimental effects to DOS games that use IRQ 0 and DSP command 0x10 to play audio.
# Setting the value way too high (above 1000000ns) can cause significant lag in DOS games.
# blaster environment variable: Whether or not to set the BLASTER environment variable automatically at startup
# sample rate limits: If set (default), limit DSP sample rate to what real hardware is limited to
# instant direct dac: If set, direct DAC output commands are instantaneous. This option is intended as a quick fix for
# games or demos that play direct DAC music/sound from the IRQ 0 timer who a) write the DSP command
# and data without polling the DSP to ensure it's ready or b) can get locked into the IRQ 0 handler
# waiting for DSP status when instructed to play at or beyond the DSP's maximum direct DAC sample rate.
# This fix allows broken Sound Blaster code to work and should not be enabled unless necessary.
# stereo control with sbpro only: Default on. If set, Sound Blaster Pro stereo is not available when emulating sb16 or sb16vibra.
# If clear, sb16 emulation will honor the sbpro stereo bit. Note that Creative SB16 cards do not
# honor the stereo bit, and this option allows DOSBox emulate that fact. Accuracy setting.
# dsp busy cycle rate: Sound Blaster 16 DSP chips appear to go busy periodically at some high clock rate
# whether the DSP is actually doing anything for the system or not. This is an accuracy
# option for Sound Blaster emulation. If this option is nonzero, it will be interpreted
# as the busy cycle rate in Hz. If zero, busy cycle will not be emulated. If -1, sound
# blaster emulation will automatically choose a setting based on the sbtype= setting
# dsp busy cycle duty: If emulating SB16 busy cycle, this value (0 to 100) controls the duty cycle of the busy cycle.
# If this option is set to -1, Sound Blaster emulation will choose a value automatically according
# to sbtype=. If 0, busy cycle emulation is disabled.
# io port aliasing: If set, Sound Blaster ports alias by not decoding the LSB of the I/O port.
# This option only applies when sbtype is set to sb1 or sb2 (not SBPro or SB16).
# This is a hack for the Electromotive Force 'Internal Damage' demo which apparently
# relies on this behavior for Sound Blaster output and should be enabled for accuracy in emulation.
