I have no idea what's going on, on twitter so don't know what you mean.
Basically the Xbox fanboys were taking the piss out of the PS fanboys because Forza does RT during gameplay and GT7 doesn't
Then it came to light that it was actually PC footage of the game with RT.
Then the Sony fan boys started taking the piss of the Xbox fan boys because it was PC footage.
Alex from DF then took some guestimates regarding frame rate, resolution and RT in Forza (Basically said that native 4k at 60fps wasn't happening with RT and questioned PC version being held back)
PS fan boys used this to further take the piss out of the Xbox fanboys.
Forza devs then confirm that only RT reflections are available during gameplay and RT GI is only available in replays and other area's.
Cue XB fan boys taking the piss out of PS fan boys again because it has RT reflections during gameplay, followed by PS fan boys taking the piss back by saying if the reflections in the PC footage look that bad then how bad is the XB version going to look.
It's been quite comical.
