I believe I have literally just come to terms that quality modding for the game may be over. Visuals play a massive part on an artist's interest when choosing a platform to display his creation, as often it serves as a portfolio, and just a Dx11 port isn't sufficient to address rF2's visuals. SlowMotion and SimHQ may offer free scratch-built material, but that may just be the only remaining sources with a lot of weight falling on S397 releasing their DLC packages (not meaning the quality would be above that of the better modders).
I'd love to see the classic and historic content with tracks to go along, in the works. For mods too.
