Shadows bring PC to a halt in HF2.
My PC though old and underpowered graphically (ATI Radeon mobility 5400 1gb) still manages to work with 3d models in an ok fashion, Not great but ok.that is until I add shadow casting. Then it goes out to 45 seconds plus a frame. Are there techniques to minimise the hit of turning on shadow casting that I should perhaps be using? I'm using point lights which I guess might not help but otherwise I'm following the compositing 3d models tutorial from @SimonKJones using a shadow catcher plane and separate shadow light with zero intensity. I'm using HF2 for this project though will switch to HF3 from now on. I doubt that will be much faster though. So any tips greatly appreciated.
