For example, darkplaces renders as fast as possible. Sound crackles a lot. When i set cl_maxfps to 125, sound works fine so the actual load on the system is important it seems. Under ioquake3 sound will be good for ca. 10 min. then start crackling/ stuttering and be ok again ca. 1 minute later, reducing resolution from 1100x1050 to 650x600 (I'm on a widescreen TFT here, this "weird" resolutions make the game display look more like 1280x1024/800x600 on a CRT) helped here too. I experienced that crackling in ioquake3 under linux too, so there may be something wrong inside ioquake3 or, more likely, the user. > > > Great work! > > > > Alf > > > > > > Btw., is there a recommended "bestest" audiocard for OpenBSD? > > I have 2 Soundblaster Live here (they work ok): > > emu0 at pci5 dev 0 function 0 "Creative Labs SoundBlaster Live" rev 0x08: > > apic 4 int 20 (irq 3) > > audio0 at emu0 > > emu1 at pci5 dev 1 function 0 "Creative Labs SoundBlaster Live" rev 0x0a: > > apic 4 int 19 (irq 11) > > audio1 at emu1 > > > > depends what you want. sound quality? multichannel? s/pdif? envy(4) > is the only real "pro" soundcard driver. > > emu(4) has good sound quality but doesn't have multichannel or > s/pdif. > > cmpci(4) has decent sound quality and is well supported as far as > multichannel and s/pdif. > > auich(4) and auvia(4) support multichannel and s/pdif with most > hardware that has those capabilities. sound quality varies, > depending largely on the codec. > > even azalia(4) is decent if you understand the mixer controls. > again, quality varies depending on the codec. > > -- > [EMAIL PROTECTED] > SDF Public Access UNIX System - http://sdf.lonestar.org > Thanks for this list, that helps a lot!
