Performances Comparisons With Novalogic's Comanche 4
Combat Helicopter Sim

Comanche 4

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.

The lead changed hands quite a few times in the Comanche 4 benchmark.  Focusing on the scores at 1024x768, we see that the GeForce FX 5950 Ultra led the pack in the default test and also in the 4X AA + 8X anisotropic filtering test, only to fall behind both Radeons again in the 4X AA and 6X AA tests.  The straight 4X AA and 6X AA tests, however, belonged to the Radeons here.  If we shift our focus down to the 1600x1200 graph, we see that the performance landscape didn't change all that much, but the GeForce FX did fall just slightly behind the Abit 9800 XT in the default configuration.

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 original 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 and again with 4X AA and 8X anisotropic filtering enable concurrently.

In some past reviews, we've pointed out that with the latest versions of their Catalyst driver suite, ATi has introduced a bug that drastically affects performance in the Wolfenstein: ET benchmark.  As you can see, the GeForce FX 5950 Ultra simply crushed the ATi powered cards in this test, regardless of what resolution or what level of anti-aliasing or anisotropic filtering were enabled.  The driver release notes for the Catalyst 4.1 drivers report that ATi is aware of this issue and they say it will be fixed in a future driver release.
