Performance hit G400 bumpmapping

Jeremy van AGN 3D heeft nog paar benchmarks gedraaid met de Expendable timedemo en z'n Matrox G400Max, met het doel om de performance hit bij gebruik van bumpmapping te meten:

Armed with a copy of Expendable and the ability to turn on and off Bump-Mapping, I used the timedemo to see what the results were. Now I am not doing a large roundup, just 1024x768x16 with both bump-mapping enabled and disabled. The results are as follows:

1024x768x16 - 36.40
Environmental bump-mapping enabled

1024x768x16 - 46.39
Environmental bump-mapping disabled

This means there is a 16.89% cut in performance to use the environmental bump mapping of the G400. Expendable has a limited use of bump-mapping, including water, vehicles and some walls. Under circumstances with widespread bump-mapping use, I am sure that there will be even up to a 50% hit in performance for using environmental bump-mapping.
