Difference between TGE 1.5 and TGEA??

#1 TGE is the core Torque platform which supports a wide variety of older hardware and has no out of the box shader support, paged terrains, etc.

TGEA is the next-generation of Torque technology, which targets current/next-gen hardware and shader support. It has terrain paging built-in and a number of tech enhancements. It is currently in early-adopter mode.

#2 EXCELLENT!
THANKS
