You won't last long here.Sony fan boys like to get their feathers ruffled, anything other than 1080 60fps has to be the Xbox fault even when first party titles are not all managing that perfectly, and frame rate issues are still being reported from eurogamer, cillax its unlikely that any dev would make a change if the difference was that slight especially if it was expected to be resolved by a driver update.
Its interesting to note however report seems to suggest the issue is that of drivers not of power...... If the Xbox had good drivers it would be as powerful (delivering the same) as the ps4, so where is the 50% pixel advantage if this is a software story?
if it is a temp driver issue and now updates are free why bother altering one to please the other when you know a fix is coming soon and a silent patch can be rolled out, only DF is going to see the difference between 900 and 1080 prior patch anyhow. Plus leaving it needing the patch helps to emphasise the issue to Microsoft so they pull their finger out.
