Quake 3 "Four" Time Demo |
|
Aging OpenGL Testing |
|
In terms of
simple raw fill rate metrics, Quake 3 Arena time demos are
still a good measure of performance. We ran the cards
in our test through only the highest resolutions and then
enabled AA and Aniso Filtering. Here are the results
and they may surprise you.
At 1280X1024
resolution Quake 3 is hardly working either card all that
rigorously, until you enable AA and Aniso Filtering.
Then something surprising happens. The AIW R9800 Pro
pulls ahead of the GeForce FX 5900 Ultra by over 12 frames
per second, with 4X AA and 8X Anisotropic Filtering enabled.
Again, NVIDIA's Aniso engine certainly isn't as efficient as
ATi's. However, when fill rate becomes the limiting
factor at 1600X1200 resolution, the GeForce FX 5900 UItra
takes the lead again.

Getting Serious With Sam |

OpenGL Gaming - Serious Sam, The Second Encounter |
|
Continuing in
the OpenGL vein, we have Serious Sam "Little Trouble" time
demos for you. We utilized
Beyond 3D's
Max Quality scripts to level the playing field for image
quality but disabling Anisotropic Filtering in this test.
Oddly enough, we
see the inverse of our Quake 3 results, here with Serious
Sam. At a lower resolution of 1024X768, the GeForce FX
5900 Ultra drops in a 10 - 15 fps advantage over the AIW
Radeon 9800 Pro. However, at 1600X1200 the cards are
in a virtual dead heat without AA and the race is much
closer even with AA enabled. These aging game engines
are rather one dimensional however, there's fill rate and oh
yes, fill rate to consider. Let's look at some
benchmarks with a little more pixel shader action going on.
