Jass NewGen Pack Questions

[Flux]

How come when I use the Test Map of the New Gen, my Warcraft 3 has better Texturel and runs faster (60 FPS) while running Warcraft 3 suddenly drop the FPS to 30 and the Texture Quality is not good (since it is in MED settings in TFT originally)?

When running Test Map again (with Texture Quality = MED in TFT ) from JNGP, the Texture suddenly becomes good. Its like running warcraft 3 through JNGP is better than running TFT.

Note: I checked the start war3 with -opengl
