geoMipTerrain general question

I have been using geoMipTerrain in my game since the begining and there is something i cant quite explain thats seems odd. This system is used to generate large terrains so that my computer can handle them but i am currently generating a 1024X1024 terrain and i would like it to be larger but it seems that the code in the manual was not designed to setup inifinite or near infinite terrain.

I say this because even with 1025X1025 heightmap my new computer seems to be somewhat disturbed to run it and if the terrain gets too large it seems to have lots of problems unless I set bruteforce to true then it takes forever to load and runs fine. Maybe I am doing something wrong I have my terrain setup exactly like the manual except I have added a bitmask for collisions and the PandaAI mavmesh system.

If anyone has any insight as to why this could be happening that would be great if you need me to post my code I will tonite as I am not by my code, I was just thinking about this and thought I would post it.

Bitmask for collisions is probably killing you.

It has to traverse a million triangles at once! I recommend working with the terrains get hight functions.

If you need physics/collisions maybe a small plane under your walker object following the couture of terrain might work?
