What makes things interesting is that they've confirmed another GT3 in the near future... current limitations are at 5 cars max per session. So with the Aston, Blancpain series will be maxed. So they'd either have to drop a car or, much more likely, there will be even more game engine improvements... basically means this game engine improvement, possibly/probably linked to DX11, needs to come before the following GT3.
Speculating is fun! Speaking of DX11... when is the release for DX12? Is iRacing forever destined to be a full version behind?
