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
