Two AA Methods in Vegas2 Comparison
We know that by the end of 06 Ubisoft Ubisoft's "Tom Clancy's Rainbow Six: Vegas," the first use of Epic's Unreal 3 engine, but subject to Unreal 3 engine birth defects, the "Tom Clancy's Rainbow Six: Vegas" is not in the game Video options which provide antialiasing options.
Today, we tested PCZILLA first time, "Tom Clancy's Rainbow Six: Vegas 2" PC version. We found that Ubisoft Ubisoft finally in the game menu option which provides antialiasing (Figure 1), a total of four anti-aliased level, None (off antialiasing), Quality Level1 (Quality 1), Quality Level2 (Quality 2), Quality Level3 (Quality 3).
We PCZILLA "Tom Clancy's Rainbow Six: Vegas 2" clearance to begin the first scene for quality evaluation contrast, the scenes including transmission towers, power lines, walls and so on the edge of the urgent need to deal with anti-aliased objects. Comparative quality evaluation using Radeon HD 3870 512MB graphics cards, with the official version of XP Catalyst 8.3 drivers, to carry out resolution 1680 x1050. We PCZILLA found antialiasing menu to select None, that is, closed antialiasing circumstances, transmission towers, power lines, the serrated edge of the wall is very clear that churn at 88 fps, the menu of options in the Antialiasing Quality Level1 (Quality 1) circumstances, transmission towers, serrated edge of the walls to improve the situation, but the jagged Line remains a serious situation, the same scene churn dropped to 59 fps, and efficiency loss of 49.15 percent in the Antialiasing menu of choices Quality Level2 (Quality 2) of the , transmission towers, serrated edge of the wall continues to be improved transmission lines zigzag situation has also improved, the same scene churn dropped to 58 fps, compared closure antialiasing circumstances, loss of efficiency 51.72%, compared Quality Level1 antialiasing performance 1.72% loss in the Antialiasing menu of choices Quality Level3 (Quality 3), the transmission tower, walls, the serrated edge of transmission lines basically eliminated, the same scene churn dropped to 54 fps, compared closure antialiasing circumstances, performance loss of 62.96 percent, compared Quality Level2 antialiasing, and efficiency loss of 7.41%.

"Tom Clancy's Rainbow Six: Vegas 2" built-in antialiasing function, in order to obtain perfect anti-aliased screen must be a loss of more than 50 per cent of the performance.
Catalyst 8.3 driver from the beginning, ATI catalyst for the driver of any built-in games Unreal 3 engine antialiasing functions. To this end, we specifically closed, "Tom Clancy's Rainbow Six: Vegas 2" built-in antialiasing function, a formal version of Catalyst 8.3 XP Unreal 3 engine built-in antialiasing function, which in the control panel settings catalyst xAA 4, use and quality compared to the first clearance above the same scene started. We PCZILLA found, and "Tom Clancy's Rainbow Six: Vegas 2" built-in Quality Level: 3 antialiasing mode compared catalyst in dealing with the built-in antialiasing functions transmission tower, the effect on the jagged walls slightly backward, and need to be carefully identify differences can be seen. At the same time, the same scene churn more serious losses, four built-in games than xAA antialiasing Quality Level3 antialiasing loss of about 22.72% effectiveness.
It is worth noting that, we found PCZILLA accident, simply use the built-in catalyst 8.3 Unreal 3 engine antialiasing function, a screen will light enhancement, closed or open the game built-in antialiasing functions can be enhanced with such illumination . Currently still can not determine which screen for screen rendering normal game. Ubisoft Ubisoft hope that the official or ATI Catalyst this team can give a reasonable explanation. (PCZILLA)
