I've been to the Ubuntu forums and I'd say 90% of the people posting with ATI cards are saying they see tearing even if they try OpenGL output.
This is what I've said here but the ATI fanatics just criticize it but I guess they don't realize the point. There's NO consistency. There's even been some people state that maybe they are not seeing the tearing. I don't understand how the same card would have tearing yet other cards of the same model won't. If you use the same video output, same driver ver. and same or similar x-server???
What the other guy saying that this 'amateurish' and the Nvidia driver doesn't do this is making the point that driver STAYS CONSISTENT. You can get the same result. How come no one can understand this?!?
Yeah, I keep asking because there's no answer that comes up the same each time. You have to have settings A, B, NOT C and then D for crying out loud!!! Some other ATI owners of HD 4xxx cards are asserting there's tearing and yet there's some people that say, there's none. Indeed, the only thing would be to BUY a card myself but if I get tearing, that's at least $100 investment. I'm trying to be a Linux user, here. If I used Windows exclusively, I'd have already bought a card by now. If I didn't care about open source, I would have bought Nvidia long ago.
