Moving to a more modern graphics engine and ditching DX9 has to be a sensible step forward to future proof the sim though. The current engine is great but it’s not viable in the long term. That said, I’m more concerned about what it means for the physics. So far Kunos have made a mess of moving to UE - the feel of ACC is much less involving than AC and miles behind R3E. Not sure why that’s the case, but you have to worry about the effect on R3Es physics (which are great) if they move to UE.
