so the ultimate question:
were is the colortrans memory pool?
I want to increase it. i hope this will stop lagging in my maps

That's one of the memory pools updated dynamically by the engine. There's no need to increase it, since the game does that on it's own. Anything involving the RedMemoryPool is dealt with in this way, from what I've read. It's in the BFront2.log errors explained thread, along with explanations for a lot of the other errors found in the log.

ok thanks

Not everything, but any of the different ParticleTransformer memory pools can be ignored. All of the others you should update. They won't affect SP if you don't, but will cause online problems without a big enough pool.
