Hi, everybody!

I'm having some serious issues with my level. I've been working on optimizing, reducing textures' resolution, polygon count, number of entities, etc. to solve some slowdown problems. As a result, it turned out to run faster, but once the slowdown problem was resolved, the level started getting quick freezes on some spots! Every time I change something on the level, the freezings move to seemingly unrelated places, and I can't identify a pattern which it can be occurring.

It's also safe to say I've been checking LOD values, clip_near/far values, mipmap sizes and all. I've been using ent_preload too, which really helped eliminating several slow places.

Can it be some programming problem? Or am I doing something wrong? Any help would be greatly appreciated.
