Dynamic light spike

I'm in the final phase of my maps construction and I seem to be having an issue. When I do my +showbudget, i'm getting a dynamic lighting spike at regular intervals. Approximately one per second. The bar goes from a steady 1/3 to max length. Kinda like a heart beat monitor or something. It's steady, then it spikes about once per second or so. This only happens when i'm in my outdoor area where I have 4 spotlights. It also still happens when I turn off my dynamic lighting on my light_spot's. Very strange. It's making my fps go from a steady 40 fps to about 5 for a split second during each spike. I'm just afraid that it will make for some anoying multiplayer if it isn't corrected. Anyone have any suggestions on how to fix this one?

btw, I have other dynamic spotlights indoors, but it's properly hidden with hint brushes, seen with mat_wireframe. I'd post a screenshot but i'm at work right now. Thanks.

When you talk about dynamic spotlights, do you mean a light_dynamic and a light_spot syncronized? I assume you do.

Dynamic lights are realy expensive, valve have chosen to use light_spot
and normal light entitys below most of their moving lamps. I'd
recommend that you remove some dynamic lightning, one or two of them
per map should be enough.

Great! I'll give that a try for sure. Thanks!

Just in case someone else runs accross the same problem that I had. The spiking was caused by some slowly strobing lights that I had set very bright just above some models. The abrupt lighting on those models is what was causing my dynamic lighting to spike during +showbudget. I just deleted those lights and the problem went away. I hope this helps someone later down the road.
