Like I said it is an utterly **** test, you can't compare 2 monitors with completely different sync ranges, 35-90 VS 30-144, of course the gsync will feel better in that case, their reasoning was stupid as well, because they wanted the gamers to experience IPS, this test isn't about the panel type etc. it is about the sync tech, so they should have compared the swift and the benq.
And yes I actually remember Gibbo saying that about the 100hz and acer screen, although still, some people can't get over the 75hz without frame skipping and iirc everyone who uses the 100hz mode has a buzzing/coil whine noise......
It is only a matter of time till someone does a driver but the problem is, none of the nvidia cards have the hardware to use adaptive sync.
