Lighting Optimisation

I’m having problems with lighting in the game, after I have 3 or so buildings the fps starts to drop to around 5-10 when looking at the buildings. I turned off shadows and it shot back up so I presume there is something wrong with shadows.

Here are my pc specs:
OS: Windows 7 64 bit
CPU: AMD FX 6300
Motherboard Gigabyte 970A-DS3
Ram: 16gb
Graphics card: AMD Radeon HD 787- 2GB

If you need any more spec info just ask, hope this helps!

Hey there @GeneralBread, welcome to the Discourse! That does sound (to me) like something is off with the shadow renderer. Going to page @not_owen_wilson (our renderer expert) to see if he has any ideas/questions. While we wait, can you confirm that your graphics drivers are up to date?

Yes it is up to date

If I was one of the developers I would really like a screen shot or two of the view when the fps drops. Just to know for sure what sort of a scene we’re talking about and maybe rule some theories out directly.

BTW: System Performance: Memory, Lights, and Lists
In this topic @not_owen_wilson explains the current renderer and why it is currently not advisable to build many lights.
I’m afraid there hasn’t been that much progress, as I’m experiencing similar problems…
I’m really hoping the light renderer is on the list for Alpha15…
