This engine is the code behind "The game Creator's" FPS Creator development tool, A powerful, yet rough FPS engine.
When I first saw FPSC X9 when there were only ver1 -15 there were so many issues regarding graphics , performance and stability and features but I still like it even it cannot pretty much be like source and other game engines But now that 16 - 19 version was released also that they are now supporting specular maps , rag dolls and etc I can now say that this engine still has hoped of competing with other game engines, nice work TGC hope you continue to make more performance , graphic and feature updates also bug fix for this engine I can't wait to see the future of FPSC.
