I've installed Warp on a 486DX2 66Mhz; 16MB RAM; Two 325 Hard Drives and a Cirrus Logic 5428 2Mb. I've download the Os2 settings and config.sys files, and worked the 3D and Warp definitions. On my background session I've choose the VGA driver for the main window and the NULL driver for the render window. But, despite all this modifications on Definitions and in config.sys I still can't get 3D Studio to render on the background. Every time I change to OS, rendering stops, meaning that 3D Studio only render in foreground. Any suggestions? Thanks in advance Alvaro Nobrega

Try modifying this line in your Config.sys to look like below: DEVICE=C:\OS2\MDOS\VSVGA.SYS /BGEXEC In other words, add the /BGEXEC parameter. — James — Choreo Motion —

James, I had already that parameter on my config.sys. I've also change the Swap path and size to 16MB. Rem the IFS=(…) line, and did some other changes. I haven't yet change the DISCACHE parameter, because I'm waiting to see the correct cache size for my system. Any more suggestions? Thanks in advance, Alvaro Nobrega

Alvaro, Make sure your 3DS display settings are less than or equal to your Desktop rez/depth, otherwise it probably won't run in the background. Unfortunately, I have heard of some systems that won't run 3DS in the background no matter _what_ the settings are. Sometimes the combination of OS, drivers, and hardware just don't add up. Before you give up hope, check everything over once more. Sometimes a subtle mistake can be hidden among the many settings. — James — Choreo Motion —

James, >>Unfortunately, I have heard of some systems that won't run 3DS in the background no matter _what_ the settings are. Sometimes the combination of OS, drivers, and hardware just don't add up.<< I've checked and everything. No mistakes and the settings are correct. I guess I have one of those systems you mentioned. 🙁 I bought Warp because of 3DS. I'll keep Warp because I like it. Thanks, Alvaro

Whether a program running in graphics mode can execute in the background for some reason depends on how well the video driver was written. You may want to look around for an updated os/2 video driver. (What card and chipset are you using?) Alternatively, you can run the background session using the vibrant null driver. That way the background session never goes into graphics mode, which means it oughta run in the background! By the way, what are your IDLE_Sensitivity settings? If your foreground session is set too high, the background session never gets any CPU cycles. I'm running my background session at 100, and my foreground session at about 30. Try running pulse and just the foreground session. Use F10 to bounce out of 3ds and look to see what cpu utilization you get when 3ds is just sitting there waiting for you to do something. If it is pegged at 100%, reduce idle_sensitivity until it drops off. LAM

Larry, >>You may want to look around for an updated os/2 video driver. (What card and chipset are you using?)<< I'm using a Cirrus 5428 VLB 2MB on a 486DX2 66MHz with 16MB. Next week I'll be upgrading for a 486DX4 100MB and buy another 16MB RAM. I've just find out that there are new drivers available in my local IBM BBS. I could not download this drivers yet because my download limit is too small. I've let a message and I hope that on Monday I will have the required access to download this drivers. This might be the problem after all. Someone told me that there where some problems with Cirrus Drives, but didn't specify which. As for the idle_sensitivity settings: Background ->100 foreground ->10 I've checked the foreground as well as the background sessions with the Pulse program and, as expect, the sessions showed no sign of activity while waiting in the background. Thanks, Alvaro

Does your "background" copy of 3DS run in a window? If so, you've got it properly configured for background execution (about the only thing that can stop you from there is "DOS_BACKGROUND_EXECUTION" set to OFF). My 3DS system blew up a couple days ago, so I can't check these things, but I set mine for 16-color VIBRANT on the MAIN display to get it to work in the background. — Doug Azzarito

Doug, I've tried both 16 VGA, and VIBRANT Drivers. Unfortunately I can't get the "background" session to run in a window. I just get a warning message saying that I can't run this video mode in a Window. I expected that with 16MB RAM and a 5428 CIRRUS VLB MB would be enough to run 3DS in background. It looks like it won't run after all. I'll be upgrading my computer next week to a 486 DX2 100Mhz with 32MB. This ought to be good enough for every program, but I suspect 3DS will not run in background in my system whatever I do. I'll give up background rendering, but I'll keep OS/2. Thanks, Alvaro

That may be why you can't run in the background. I can ask some of the video gurus around here for some suggestions, but first tell me how you have OS/2's desktop configured (go to the System Setup folder and open the SYSTEM object to check your resolution setting). — Doug Azzarito

Doug, I'm running OS/2 with a resolution of 640×480 256 colours. As for 3DS, I have the vibrant 640X480, 256 driver for the foreground session and 16 colours for the background session. I understand, that there are new cirrus drivers on OS2SUPORT FORUM, but I can't download it from CompuServe because Lisbon access is still 2400 baud (it would take hours). I've just checked with and local IBM BBS as those new drivers. Unfortunately as I've visited this BBS for the first time, I don't have enough download limit for downloading this drivers. I left a message, and I expect to be granted more access next week. Thanks, Alvaro
