framerate with random dynamic terrain loading

Does a 6.7 framerate effect a random dynamic terrain loading script in the bge?

Yes, it does.

Lol, no, this reverses cause and effect.

Your script (most-likely) runs within a single frame. It blocks the engine until it finished. Unless it is super-fast, it will cause a one frame lag … but for that one frame only. Getting the newly added objects will increase the load on the processing (render, logic animation …). So it might result in lower frame rate than before.

The frame rate is the effect, rather than the cause.

This is different when you load asynchronously. This method will expand the duration of the load process over several frames. This increases the workload during that period. Due to the already low frame rate (the system already overheated) it will be lower during loading.

In general: 6.7 fps are way too slow even without loading more stuff.

So the lod system would solve the problem?

Maybe, I can’t tell.
