TGEA 1.8 Slow on MacBook

Hi, I tried TGEA 1.8 in my MacBook with intel X3100 and it was really slow (below 4 FPS in stronghold)
it's only my MacBook, or someone else have the same problem?

This macBook isn't a game machine, but TGE 1.5.2 can run stronghold at ~25 FPS, this isn't a great performance, but is playable.

I'll try to optimize things later, if someone have any idea, please, let me know.

Thanks.
