Hi thanks fo reply!!, im in DOS, using for playback, quickview pro

- Picogus is in USB mode
- Video is a Cinepack 12fps, 320x200 video, tried ADPCM 22khz mono audio or PCM 8bit 11khz, interleave every frame. Video is 40min long, 560mb, then 230-250kb sec
- Tried too msvideo 1 256colors, 12fps, same audio options and interleave, 640mb more or less 270kb sec
- Tried iso and cue/bin

Bot videos i burn in CD and test in a 4x IDE drive and play fine, from HDD too

Using Picogus CD give me stops every 2 or 3 seconds because frameskip

Hi! i get consistent 600kb sec transfer rates in speedsys, and i can confirm by copy a file in DOS is correct

The attachment IMG_20260414_092524.jpg is no longer available

In fact my IDE 4x drive is slower, because i think i use CDRW unit and the unit is old, read at 360-420kb sec, but anyways video play smooth from real CD

I dont have a IO recovery period option in bios

thanks!

I wonder if the MKE cdrom has naturally higher CPU overhead and its running out of CPU power to copy from ISA bus and decode at the same time

I tested in a pentium 200 and videos are slow too using picogus

Funny thing is that msvideo1 avi play smoth from HDD in a 286 25mhz

Maybe is ISA bus that saturate?

The only videos i can play smoth using picogus CD is msvideo1 optimized for CDrom playback at 150k

Im testing more cd emulation, and at least in my motherboard?¿ can someone help me to test, i think is very cpu consuming

Im testing game The DIG, this game need a DX/2 66, i have a DLC33, of course MUCH slower than minimum, but anyways, if i play from HDD or IDE CD, the game is a little slow, but playable. Using Picogus CD emulation, in USB or SB mode, is same, the game became unplayable, too slow

Any ideas? or is just picogus cd emulation that consume too high CPU?

thanks!!!!

Are you playing the game in DOS or Win9x? If it's in win9x, use the latest firmware version and swap to the microsoft MKE drivers instead of Creative. The Creative MKE driver blocks the CPU like crazy.

Also because the MKE interface doesn’t use IRQs or DMA it does burn a lot of CPU time polling and transferring data.

The game calls for a 486DX2/66 and 2x speed CD-ROM under DOS, you would think that means it's fairly safe for an MKE drive

thanks, i had similar problem with my 1x mitsumi cdrom until change driver to one using dma

But you say the problem is interface no driver then? no solution with diferent driver or parametes?

thanks a lot
