Hey. Thanks for the reply. I just checked, everything is blue. Not very much going on at all, this is really perplexing me. Because there isn’t much going on in this scene at all. There are 364 actors all of them static. 8 dynamic lights only 4 of them casting shadows. Light complexity shows this isn’t a (massive) issue. I also removed all the lights for testing, Which did fire the fps back up to 120 but this is surely to be expected with dynamic lights and doesn’t explain the discrepency between versions.
