I am not the designer of the map compiler so I cannot say for sure. But you dont place your portals manually in GS. So the map compiler has to find portals on his own and finds much more than you would place manually. Probably it creates a huge amount of data to traverse.
All this happens on CPU. This also explains why exchanging a graphics card did not speed up rendering BSP levels made with GS, only exchanging CPU could help there.

the a7 map compiler primarily calculates the static shadow maps. i think most users don't use the old BSP mode anymore which also takes a lot of time for visibility calculations.

According to a question asked by a user of Unity and according to the answer by one of the developers, Unity does not have LOD (except for terrain) and will not in v2.5. Here is the link to the page:

Hello Dan,
Some Game Engine users (from many Forum threads) expect so much from "Unity".All of the sudden many users decided "Unity" is the solution to everything "Indie Game development".Well;it's not and will never be;regardless of the Windows platform. Oh yeah!,Unity is hot but so is many other Engines out there.These Engines all have their own places of importance;for example: 3DGS A7 vs Unity:

3DGS Price tag Unity Price tag
///// ///////// /////// /////////
1)Excellent < $1000 Excellent > $1000

2)3DGS?;User friendly Unity?;Some learning curves

3)3DGS?;Graphical fedility
a)UnityGraphical fedility?;run blazing fast basically high end tool set up.
a)3DGS;Runs fast but not blazing
fast


The lists of simple tools available and not available in both Engines goes On and on.....it doesn't really matter much in terms of the best "Indie Engine",There was a time when "Torque" was the top of the list and 3DGS was not "so-called" good enough......,that came to pass;now it's "Unity"...OK!...we shall see!.3DGS will always win because of the expectations people look for that's just a wet dreams....it's always come to pass and users run back to 3DGS (Silently)...hoping no one notice!....0__0

I suppose you 've been through all these pages and everything they have listed there:

been there(your first post)
thnx(your second post)

You welcome

I see more and more Gamestudio users on Unity's beta list.

The Unity manual contains some information about how to set up occlusion culling for indoor levels. I haven´t looked into it in detail but i think you can have optimized indoor levels in Unity too.

This is interesting. I have to check that out. Thanks for the info.
