VSPEED 1.30 changes since version 1.23
---------------------------------------
- Resolved bug (missing points) in truecolor rainbow screen test.
One point consists of 3 byte but this was split away by the 64k
segment boundary! Finally I had to switch bank within my putpixel routine.
- Vspeed now does not test modes if onboard memory is not enough for it.
- Overflow bug in the bank switch time measuring.
- Speed values on fast Pentiums showed weird values; now it works well.
- File output.
- Support for 32 bit truecolor modes.
Some remarks
------------
Biggest screen refresh may cause significant decrease in video speed.
Data fragments of my SPEED-64 (ArkLogic 2000PV proc., 2M RAM) Card:
(Pentium 120MHz, Intel Triton 512 Burst cache).
register->video memory fill:
55 MBytes/sec at 320x200/256
60 MBytes/sec at 1024x768/65536 (60Hz NI)
71 MBytes/sec at 640x480/TrueColor
320x200 normal zoomrotation: 135.7 frame/sec
1024x768 tiled zoomrotation: 38.1 frame/sec
Use the generic UNIVBE TSR program (Universal VESA BIOS Extension) for
VESA BIOS v2.0. (Supporting protected mode linear access to full video RAM!).
Version 5.2 is under beta testing (1996. May). Try ftp.scitechsoft.com.
VBE 2.0 compliant SVGA library kit is also available there.
That's all, folks...
