2011 15" MBP 6750m, Steam + Half Life 2 = Choppy?

[Ceebee1980]

So I installed Steam and Half Life 2 Demo on my 2011 15" MBP with 6750m.
I tested it out, and I seem to get great FPS at any resolution settings.
The problem is that when I "look" around the room or environment, I get this weird horizontal choppy effect where buildings and objects aren't lined up perfectly right. Basically it's as if the image is getting cut, and the bottom or top half is lagging behind by a few frames.
Is anyone else having this prob? Could it be an OpenGL and/or 6750m issue?

Enable VSYNC that should fix it. It's a well known fact that the MacOS video drivers are crap and have ridiculous amounts of tearing

Open Half Life 2 > Go to Options > Video > Advanced > Wait for vertical sync > Select Enabled > Click apply

Thanks brohams. Let me try this out and see if it works.
So you guys think that it's definitely a driver/tearing issue and not a hardware issue? I don't seem to have any temperature issues.

Yes, it sounds like a textbook case of tearing:

Yeah, I'm not sure it's just a Mac OSX problem. Windows is the same.

You'd think that software writers would know to put up a new frame when it's ready, not when it's still being drawn (even if it's 2ms slow). Personally, I think that's a pretty obvious oversight.

Thanks! Seems like VSYNC fixed it. It's weird, because I feel like I had VSYNC on the first time already =/
Wonder if it was related to integrated/discrete issues. Hmm....
It seems like too many new technologies were introduced for Apple to keep up with on these MBPs. Wish 10.6.8 would come along lol
