Electronic Arts talks about differences in graphics on Tiger Woods for each console and why Wii is different.
In a recent interview about their golfing title Tiger Woods, EA had this to say:
"So the horsepower of the Wii is not quite up to the par of the 360. It's a little bit better than what we saw on the Xbox and PS2. So the graphics fall somewhere in between, you know, the PS2/Xbox and the 360."
"We do support 480p widescreen, we updated a lot of textures; the sky domes and the courses were all retouched, so they are updated as far as better than PS2 and Xbox. But they're not as up to par as Xbox 360 and PS3, which is understandable because that's what Nintendo is kind of going for. They're just trying to revolutionize the gameplay, instead of revolutionize graphics."
