Gryzor Posted January 8, 2022 Posted January 8, 2022 (edited) I posted this many times. It seems to me there is a bug related with "enlargegment" of flat shadows specially at 5 minutes interval, during dusk and dawns, that cause ENORMOUS / HUGE fps / frametime GPU reduction. Specially its quite noticeable over forest or big cities (I posted this bug many times in other threads, since many years ag). I post 3 tracks at different times. 4:28 AM, 4:35 AM and 4:45 AM. As you can see, exactly in 4:28 AM track, just before the sun rise, there is a HUGE fps reduction, everytime flat shadows are enabled. After five minutes, FPS becomes normal. With flat shadows off, there is no penalty reduction. Please ED, look at this because I think I posted about this bug many times, or at least, make us possible to disable flat shadowing WITHOUT disableing terrain and mountain shadows, just before shaders encryptation in 2.7.8 we can disable by modding a shader file. I attach other thread I started that refers other issues caused by flatshadowing. @ED: COULD YOU MAKE US POSSIBLE PLEASE TO DISABLE ONY FLAT RENDERED SHADOWS, WHILE MAINTAIN OTHER TERRAIN SHADOWS ENEABLED?? or at least fix this huge performance drawback that occurs at very exact moment.
