| Hi, before again bothering the KIEV folks with that question, I'll post it here, as there might be one or the other fellow user who can give me a hint on what to do...: The (relevant parts of) system hardware config is: The trouble is, that (as always) the same system running Win98SE will show great, flawless, full-synced DVD playback. What the heck is the cause of the slow performance in Warp? SCSI? Thanks for any suggestions. |

| I've the same SCSI DVD-ROM model and i experience the same problem. Besides this AND the well known problem of some(?) Pioneer drives that cant play AudioCD on /2, the drive seems to work flawlessly. Maybe this has something to do with the WarpVision itself. Have you tried it with some ATA DVD-ROM drive? If you do pls post ![]() vagy |

| Hi, thanks for the confirmation. Well I might swap the DVD into my wife's PC as she is running Windoze and get myself a IDE DVD drive. Although this is sad, as I actually want to avoid having a mixed setup (SCSI + IDE). I'll let you know if there's anything new... |

| Well, I do have the same DVD-drive (Pioneer DVD-303S), an Athlon 500 and 128 MB RAM. With the present WV-version I can watch DVD-movies, but it is not very pleasant: synchronisaton is kept, but frames are dropped, i.e. I do not see smooth movements but rather discrete ones. Before I attained this state, it was similar to your description. There are several factors influencing WV-performance. 1st of all I recommend to read the following article very carefully: http://www.os2voice.org/VNL/past_issues/VNL0303H/vnewsf4.htm Then, there are a few things to optimize: 1. Adjust the priority to 1 (one). This is the highest priority and not 4 ! Do this in the WVGUI- configuration menu. This has boosted the performance on my system. You can also try to set the priority of all other processes to 4. Watchcat together with the "nice"-dll (from Hobbes) can adjust the priority for any process. 2. Use Scitech Display Doctor as your video driver. You can use the OEM version released to IBM and available from the eCS website for registered eCS users. 3. Obtain and register Warpoverlay from the Kiev elephant site. This switches hardware avcceleration on but only if you use the Scitech Display doctor. By the way, your the performance of your video card is crucial. I have a Matrox G450. 4. It may also help if you choose as your horizontal frequency a multiple of the frame rate of the DVD. A PAL-compatible DVD has approx. 25Hz framerate, hence 75Hz for your video mode would be advisable. 5. You should have the most recent version of the UDF-filesystem drivers. Presently version 2.01 from July 2002. Loas udf.ifs befor cdfs.ifs!!! 6. There is a utility on Hobbes to activate the framebuffer on your videocard (p6k7mtrr_v008a.zip). You can also give this a try, parallel to using SDD and Warpoverlay. 7. Disable any postprocessing in the configuration menu of WV. Postprocessing consumes only processor power and thus decelerates your processor. 8. Did I forget anything ? Well, may be, use the most recent version of WVGUI resp. WVCLI. The most recent version of WVGUI worked better for me than WVCLI. Your processor is a bit more powerful than mine, finally, you should get a slightly better result than me. |

Thanks a lot for the suggestions. At least, it kept me thinking of the problem. In the meanwhile I wrote to the KIEV guys and as it seems by their response, they might suspect the DVD disc to be dusty/scratched.... which is not the fact, as it's a brand new one. Unfortunately it's the only DVD I got. Again, Thanks! |

| If you have a recent kernel, the last year or so then in the config.sys put CLOCKSCALE=4 notice no set in front of it just the line. Andy |

| Again "oops" ! Without the "SET" in front, I get an error message at bootup stating that this line will be skipped... seems like the "SET" is somehow necessary. Strange thing... does it work on your system that way? What Warp version are you running then? Cheers |

| You seem to have done everything correctly. Your guess that it depends on the DVD may be correct, I do not know. I have tested it extensively, with good results, with "Lord of the Rings 1". Another difference is your video card, it is a Matrox G200, which is a bit slower and older than mine (G400). |

| You should also try to select the least ressources consuming audio track, i.e. 5+1 surround sound requires more processing power than plain stereo. |

Oh come on! I'm an OS/2 user!! One never knows with multimedia stuff on OS/2: You turn on an option that looks harmless at first sight and - whooom! - something is burning, melting or dissolving inside your machine. Thanks anyway! |

This means that you are using an older kernel. Some time ago (late 2001 I think) this was added to the kernel. And there was a new CLOCK01.SYS to go with it. Both are needed for it to work, but, the newer kernels are needed to recognise the CLOCKSCALE statement in the CONFIG.SYS. The kernels came out on IBM's testcase ftp site. OS2Site has the latest ones at http://www.os2site.com/sw/upgrades/kernal/index.html. Unfotunately, these don't include CLOCK01.SYS anymore as I believe this was added to an MCP build or a fixpacks. Also, on the matter of the frame buffers/write-combining mentioned earlier, this was added to the Scitech drivers some time ago. I think it was in the later beta versions of SDD, but, it is definitely in SNAP. To see if it is being turned on, look in the GRAPHICS.LOG. David |

Hmm... I'm using Warp MCP from off the eCS 1.0 CDs... so I might need to check for updated kernels, right? And for a newer CLOCK01.SYS somwehere... maybe some good soul has it available somewhere too. At least, I'll check at the ftp site of IBM... Thanks for your support! |

| Get the eCSMT tool from www.ecomstation.com. It will pull up the updates for that are available for eCS. If you install fixpak 3 you will be updated enough with it. or there are kernals available there too. Andy |
