Comanche
4
|
To
give you sim fans a small taste of what these cards can
do, we
used Novalogic's combat helicopter simulator Comanche 4
for our next batch of DirectX tests. Comanche 4 uses DX8
class pixel and vertex shaders to produce some of the
realistic visuals used throughout the game. Unlike some
of the previous tests though, this benchmark is heavily
influenced by CPU and system memory performance,
especially at lower resolutions. However, when the
resolution is raised and anti-aliasing and anisotropic
filtering are enabled, the current crop of 3D
accelerators
tend to slow down quite a bit. |
Like the Unreal Tournament 2004
demo, the GeForce 6800 Ultra was CPU bound when the
resolution was set to 1024x768 in the Comanche 4 benchmark.
However, the Radeon 9800 XT's and the GeForce FX 5950
Ultra's performance dropped by about 10% at 1024x768 when AA
and aniso were enabled. With the resolution cranked up
to 1600x1200, performance begun to scale accordingly and the
GeForce 6800 Ultra proceeded to thump the competition yet
again by
margins ranging from about 5% to 60%.

Wolfenstein: ET
|
We also ran
through a batch of timedemos with the OpenGL game
Wolfenstein: Enemy Territory. Wolfenstein: ET is a free,
standalone multiplayer game that is based on the
excellent Return to Castle Wolfenstein, that was
released a few years back. It uses a heavily modified
version of the Quake 3 engine, which makes it a very easy
to use benchmarking tool. We created our own custom demo and
used the built-in timedemo feature to check each card's
frame-rate. The tests below were run at 1024x768 and
again at 1600x1200, without anti-aliasing, with 4X AA,
with 4X AA and 8X aniso and lastly with 4X AA and 16X
anisotropic filtering enabled
concurrently. |
The GeForce 6800 Ultra pummeled
the competition, when we tested it with Wolfenstein: Enemy
Territory and our custom timedemo. Without any
anti-aliasing or anisotropic filtering enabled, the 6800
Ultra was between 3% and 35% faster than the GeForce FX 5950
Ultra at 1024x768, and about 9% - 29% faster then the Radeon
9800 XT. With AA and Aniso enabled however, the GeForce
6800 Ultra's lead increases to over 40% in some test
configurations. Notably, ATi seems to have fixed the
performance issues they had in this game with their latest
drivers, but no amount of driver tweaking would have helped
them catch the 6800 Ultra here.
