开了抗锯齿之后,效果明显吗
还在TEST~~
这是别人的A卡 TEST
Here are three comparisons of the game I made, using ATi Catalyst to force different AA settings:
1) No AA, Default

2) Morphological AA Enabled

3) Forced 8x AA

4) Forced 2x AA, Super Sampled

5) Forced 2x AA, Multi Sampled

Clearly forcing AA through Catalyst works. However, here's the bad: it severely impacts performance. I run the game across three monitors at 60fps, never dropping below that, at 0x AA, but when I bumped it up to 8x I was running at around 30fps, and there were times where the game literally dropped to 1 or 2 frames per second, seemingly whenever traffic passed by.
2x AA is playable, with my frames rarely dropping below 40fps, and that "freeze" effect was gone, but I'd rather have the constant 60fps than the marginal increase in image quality at this point. On a single monitor, though, I have no doubt I could enable 4x or even 8x AA again and stay at a solid 60fps.
Morphological AA is only available on Radeon 6k series cards, and it really hits performance hard (dropping my 60fps down to around 35fps) for what I feel is an imperceptible difference. I know it can help on some games, but it appeared to only negatively affect the frame rate in Hot Pursuit. Also, it really distorts the text and menus of the game (because it's a post-processing "edge blurring" effect), which I don't like at all. Still, it is an option.
I'll play around a bit more, but at least it seems that forcing it on does indeed work.
