WINBENCH
PC Labs Windows Graphics Benchmark
Version 2.0 - 20 Oct 91
1. Contents of the final release:
WINBENCH.EXE WINBENCH executable
WINBENCH.HLP Help file
WINBENCH.DOC This file in ASCII text format
*.XLS Sample reports used by the Compare Results menu
2. Installation and use:
The Windows Graphics Benchmark program is located in the WINBENCH
subdirectory on the benchmark installation disk. The file WINBEN2.EXE
is a self-extracting archive. To install WINBENCH on your machine
copy the WINBEN2.EXE file to the desired directory on your hard drive
and type WINBEN2. Run WINBENCH like any Windows application. For
example, the DOS command "win winbench" will launch WINBENCH from the
current directory.
WINBENCH writes the files containing test results to the directory from
which it was launched. Generally, you should launch WINBENCH from the
same directory every time. This avoids having test results scattered
about your hard disk.
For other information about WINBENCH, see the help dialogue box.
3. A summary of the differences in WINBENCH 2.0 from WINBENCH 1.1:
- System Information adds the processor type and clock speed,
presence of math coprocessor, Windows version number and operating mode,
video driver file name and description, video driver file date, video
driver version, X-Width Aspect Ratio, Y-Width Aspect Ratio, height of
the system font, and average character width of the system font. All
system information is written to the report file.
- All tests now run for a minimum of five seconds, and report
throughput, rather than elapsed time. There is no method to convert
results from WINBENCH 1.1 into the format for the results used by
WINBENCH 2.0. Many of the tests are upgraded to be consistent with
Windows 3.0.
- All tests display text centered in the benchmark window to identify
the current test being run in a series of tests. Identifying the test
when it is running improves human factors and helps to debug WINBENCH
and Windows should WINBENCH terminate with an UAE.
- Many tests change the color being displayed to give a better visual
indication that something is actually being done while the test runs.
- Where possible, throughput is either calculated or estimated as
"pixels/sec". Results of text handling benchmarks are reported in
"characters/sec". Results for some other tests are reported in
"operations/sec".
- The Ellipse (Curves) test renames the WINBENCH 1.1 Full Arcs test,
which drew ellipses on the screen then filled the ellipse with the
current brush. The Ellipse test also draws ellipses on the screen, but
it varies the brush color used to fill the ellipse.
- The Patterns (Rectangles) test now runs ten tests, using a black
fill pattern, seven grey patterns, a white pattern, and a set of hatched
patterns.
- The Scroll Text (Text) tests are new. They display and scroll a
full screen of text using the same five fonts as displayed by the Image
Text (Text) tests.
- The Mixed Fonts (Text) test uses Courier fonts rather than System
fonts. With Windows 3.0, it is not possible to display a system font
with a bold attribute.
- The Help dialogue box provides a complete description of all tests.
- The Modify Options menu writes to the WINBENCH.INI file in a
section called [Version.2.0] when you choose to save selected
parameters. WINBENCH 1.1 used the [Bench] section of WIN.INI for the
same purpose.
- The ASCII text report file now lines up data in vertical columns.
The "1-2-3" format for a report file produces comma-separated data, and
non-numeric literals are bounded by double quotes, e.g. "sample text".
The Excel format produces tab-separated data.
- Because all tests run for at least five seconds, there is no need
to use radio buttons to select the number of test iterations. These
radio buttons are removed from WINBENCH 2.0.
- If you run all tests or run in demo mode, WINBENCH displays an
appropriate message on screen when it is done.
- If WINBENCH is run in real mode and there is enough memory to load
it, it displays the initial dialog box, then a message box saying that
it does not run in real mode, and terminates. If there is not enough
memory to load it, then Windows displays a message box with an
application error.
- The Compare Results menu choice presents a pair of dialog boxes.
The first one displays a list of existing .XLS files, from which one is
selected to compare with the results of testing the current video card
and driver. The second dialog box displays test results for the current
card and the selected card inside a list box. The results of each test
written to the report file now all have unique names so that the Compare
Results dialog box can operate properly.
- WINBENCH 2.0 was compiled with Microsoft C6.0a, the Windows 3.0
SDK, and Borland's Workshop resource editor. Borland C++ 2.0 was used
during the development of WINBENCH, because it is superior to C6.0a for
rapid program development, debugging, and testing.
5. If you have problems:
- Please note and report any test results that seem to be incorrect,
including zero and negative results. These indicate that the test being
run uses an incorrect throughput calculation, either roundoff or
overflow.
- Please provide hard copy or electronic copy of test results with
any problems, and describe the video graphics adapter being used if both
the Benchmark Results title and the System Information are not self-
descriptive.
Thank you.
