Entry Name: Visions Entry Number: 36 Description: 3D demo running at high frame-rates Written by: Andrew Nicolle The demo features 5 scenes demonstrating various capabilities of the 3Dfx chipset. All effects have been optimised to provide maximum frame-rates on standard 4Mb Voodoo cards. In addition, the 800x600 mode is supported on Voodoo 2 cards to take advantage of their greatly increased speed. Requirements: ------------ Pentium processor (Pentium 166 or higher recommended) 24Mb RAM (Possibly less!) 1Mb of harddisk space 4Mb Voodoo Graphics card (3Dfx) with Glide 2.43 or higher Windows 95 or Windows NT Operating System Command-line switches: --------------------- The following command-line switches can be used to alter the behaviour of the demo. These can be used either by DOS batch files or by creating short-cuts to the demo and altering the parameters. -fps Display frame rates at end of demo -loop Loops the demo continuously -800 Set 800x600 display mode (Voodoo 2 only) -novsync Turn off vertical retrace syncing (improves performance) For example, the following will display a frame rate summary and turn-off vertical retrace syncing: visions -fps -novsync The demo can be stopped at any time by pressing ESC. Frame-rate statistics will be displayed if these have been enabled. Performance summary ------------------- The following frame rates were obtained for a Pentium 200 with 64Mb RAM and a Monster 3D card using the -novsync option (the number of Vertices and Faces displayed is listed also): Motion Blur: 73.4 fps (Verts: 916 Faces: 3608) Visions: 95.7 fps (Verts: 376 Faces: 728) Water: 80.2 fps (Verts: 1048 Faces: 1990) Rotozoomer: 84.3 fps (Verts: 390 Faces: 730) Earth Zoom: 173.5 fps (Verts: 546 Faces: 1080) Compatibility ------------- The demo has been tested under Windows 95 and Windows NT with no known problems. This demo supports Voodoo, Voodoo Rush, and Voodoo 2 based 3D cards. Random lock-ups were reported on Voodoo Rush cards with an early beta of this demo, and there may still be problems in this version. The demo will run in 800x600 mode on cards with 4Mb of frame buffer memory (ie Voodoo 2) through the use of the -800 command line switch. This has not been tested on a Voodoo 2 card, but there shouldn't be any problems. Let me know how it runs if you have a Voodoo 2!
