Battlefield: Vietnam (DirectX)
Battlefield: Vietnam picks up on Battlefield 1942’s success and uses a similar, but slightly modified engine to add more detail to the terrain and characters.
For this game we used a manual run through of the game, in particular a run through the “Reclaiming Hue” level. I simply turned on a trainer that allowed me god mode, and ran from one corner of the map, through a designated path, to the other corner. This captured the fighting of the enemy characters in my face and everything, so it should be a pretty close approximation to real gameplay. At the end of the framerate graphs, you’ll notice a big plunge in frame rate; this is caused by me zooming in a set of trees at the end of my run and looking past them — something I found taxed the video system pretty heavily on these cards. And since you’ll probably be zooming while playing, it just makes sense!
These three cards perform pretty closely to one another at this level of detail but it is interesting to see the overclocked 6800 take the avg FPS win away from the X800 Pro on the latter test.
AT 4xAA and 8xAF, these cards are reaching their playability limit as the min FPS point comes down to around 20 frames per second. The AA6800 does a good job here over the stock 6800 with a better average FPS and maximum FPS. The extra power of the X800 Pro card is starting to sink here too.
You’ll no doubt notice how miserably the ATI X800 Pro fell behind in the 16×12 0x0x test; we found a bug in the 4.9 Catalyst drivers I think. In BF:V, the ATI card refused to play at 1600×1200 resolution without having AA and AF enabled. We tried reinstalling the driver, adjusting and readjusting the driver settings, but nothing seemed to work. Obviously we can’t compare how the ATI card did against the NVIDIA on that test, but we still can on the 4xAA and 8xAF test.
Again the extra speed of the AA6800 was able to put it ahead of the X800 Pro where as the standard 6800 fell behind. On the 0xAA and 0xAF tests, the Chaintech 6800 card seemed much more playable with a higher minimum and average framerate.
