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 benchmarks. 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, 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 video cards tend to slow down quite a bit.

With the resolution set to 1024x768 in the Comanche 4 benchmark, all of the cards performed similarly.  With 4X AA enabled at the same resolution, the 9800 XTs and 5950 Ultra held the same pace, but the 5700 Ultra's performance dropped off quite a bit.  When we enabled 6X AA, however, the Radeon 9800 XTs walk away with a decisive win, but they lost some ground when 8X anisotropic filtering was enabled along with 4X AA.  The graph representing the performance levels at 1600x1200 somewhat mirrors what we saw at 1024x768, but at the higher resolution, the GeForce was able to nudge ahead of the 9800 XTs by a few frames per second when 4X AA and 8X aniso were enabled simultaneously.

Benchmarks / Comparison With Wolfenstein: Enemy Territory

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, which 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 a 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.

Both of the Radeon 9800 XTs performed well in our custom Wolfenstein Enemy Territory benchmark, with the Sapphire card pulling slightly ahead of the Asus card, but the GeForce FX 5950 Ultra dominated here.  At both resolution, regardless of what level of anti-aliasing or anisotropic filtering was used, the GeForce FX 5950 Ultra held onto a sizable lead.  The GeForce FX 5700 Ultra also performed well, almost catching the Radeon 9800 XTs at 1024x768.
