I know I must be misreading the chart in some way...but I can't figure
out how. The times on Deskstation's chart look to be based on benchmarks
calculated from rendering the following:
= "SpaceFighters" Frame #130, Antialiasing [High], Trace Reflections,
Refractions, Shadows [On], Depth of Field [On], and
- "TextureExample" Frame #1, Antialiasing [High], Trace Reflections,
Refractions, Shadows [On], Depth of Field [On]
Here's what the chart says:
Raptor 3 (Alpha |==========================================61
21164/300) |-------------------------39
+
Raptor 3 (Alpha |==================================53
21164/266) |----------------------34

Raptor IIA (Alpha |====================30
21064A/275) |-----------19
+
Raptor 3 (R4600/133) |==========18
|--------14

Raptor II (R4600/133) |=========15
|-------12

Pentium 90 |======10
|-----9
