there is something that needs to be fixed.
Inoticed yesterday during really heavy rain; that if Iwere to ‘freeze frame’ the screen, that Iwould have the missle command type rain that Ihad seen months ago in these forums (as shown on consoles after extreme slowdown).
I couldn’t help but notice my framerate was 20% down. something was hitting the render engine harder in extreme rain. So Ilooked a little deeper.
It looks like a pass is being done to flatten the rain (putting several ‘rains’ together) when the super heavy rain is happening. This pass/process has a slight glitch.
Whilst I couldnt get the game below 50 frames per second (couldn’t recreate the slowness)- Icould see that if Idid have a ‘freeze frame’ at this point; the rain would have a ‘low res’ missle command look.
It is actually several rain drops from differing directions being passed together. If the background layers of rain were not also happening, or due to a render issue, the framerate got really low, I can see how that ‘missile command’ graphic could be going around.
at sixty frames per second that same ‘missile command’ graphic actually looks really convincing. it is rain from mulitple directions.
In the heaviest rain pattern the engine did hiccup a bit… if that same hiccup happened on a system on the borderline of running… it could lead to a slide show (Id imagine).
Something in passing the rain layers together in the thickest rain causes a render hit.
