I do indeedy. Diddly squat if developers don't put it to use. Are publishers going to pay for the extra dev time if it wont bring in extra profit?
How many times have PC gamers complained about lazy ports? You think this will be any different? First time for everything I guess? The bets we are likely to see is the same performance on both systems being seen as "good enough" by publishers.
The faster gpu either allows you to run the same game at faster fps, or with settings turned up at the same fps.
Devs have been making scalable engines for the massively variable pc market for years and years, and with the two boxes being so architecturally similar it will be nothing to apply the same here.
