Straight to the point.

When I run my map the Dynamic Light Rendering bar on '+showbudget' is contsantly on max. I have 30 normal 'light' entities in a very large room. Now, is this too many lights or is it just my poor system?

A clearer example, here is a pic of my map with all the lights... cs_alcatraz

Normal lights don't affect performance because their effects are precalculated during VRAD. Dynamic lights do though. A lot. Even one dynamic light in a complex scene can drop your framerate to half or less, even if you can't see it from where you're standing. Things that can produce dynamic light include point_spotlights, light_dynamics (obviously), env_fires, and probably some others too. So, find any of those and either set them to not produce dynamic light or delete them.

And, as a style issue, you should probably halve the brightness of the lights you have (or more). It looks almost fullbright the way it is now.

It seems to me that any kind of model lighting is also included as dynamic lighting, but I could be wrong :/

I think so as well... seriously I am not an idiot and trust me, the only lights that I have in my map are normal 'light' entities.

I will probly change the birghtness on the lights, i used to have it not as bright before but then you couldn't see in every other cell which would make everyone camp in cells

I am just going to continue my map how i'm doing it and at the end of it, if there is too much of an impact on FPS, I will work on the light problem. If there is barely an impact, i'll leave it.
