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.

Wow, there is a lot to talk about with regard to the Comanche 4 benchmarks.  Without any anti-aliasing, all of the cards performed similarly, save for a few frames per second here and there.  With 4X AA enabled, the 5950 and 9800 XT again performed at similar levels, but the 5700 Ultra had a clear advantage over the 9600 XT.  When we then switched on anisotropic filtering as well, the performance deltas were even more pronounced.  With 6X anti-aliasing enabled, the Radeons were superior at 1024x768, and the 9800 XT came out on top again at 1600x1200, but at the higher resolution the 5700 Ultra with its huge memory bandwidth advantage skunked the 9600 XT (14.4GB/s vs. 9.6GB/s).

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 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 1600x1200, with out anti-aliasing, with 4X AA and again with 4X AA and 8X anisotropic filtering.

I know the crew and I here at HotHardware.Com are glad that we've finally eliminated Quake 3 from our video card test suite in favor of the much newer Wolfenstein: Enemy Territory benchmark, but the folks at ATi (and Asus) are probably none too pleased!  The GeForce FX 5950 Ultra and 5700 Ultra smoked the Asus Radeon 9800 XT and 9600 XT at both resolutions, regardless of what level of anti-aliasing was enabled.  It seems like ATi may have a bit of work to do with their OpenGL ICD.
