So, i have made my test runs on editor, 200-300fps, all works fine. But after i build .exe version and test it on same pc i have very bad fps drop, game dosent lag but all moving is like slowmotion, mouse has huge delay and moving. but my sun time cycle works. What could cause this?
the stat dialog from game window (inside Unity) is not actually the real fps counting… (i don´t why is it)…
you can pick up a script to print your real fps on screen…
take a look at this script:
stat is great to look other infos like drawcalls, memory usage, animation counts… and so… 
Currently with fps script i have 40-50 fps at highest settings 1680x1050 resolution. I noticed that after i added image effects. And profiler shows that those uses 10-15% of GPU power. Currently there is 80% power cycle at rendering, how to reduce that? could i use occulsion culling at small scenes to reduce draw calls? Any ideas are welcome
